Deborah Weatherspoon, PhD, RN, CRNA Answers represent the opinions of our medical experts. Renal glycosuria is a rare inherited condition where your body eliminates sugar in your urine even though your blood levels are normal. She has constant dull left flank pain that becomes sharp with voiding. In healthy persons, the glomerular capillary wall is permeable only to substances with a molecular weight of less than 20,000 Daltons. It can also appear quickly, over some weeks. A complete urinalysis evaluates several different aspects of your urine through physical, chemical, and microscopic examination. Inform the patient that he has a urinary tract infection, obtain a urine culture, and treat with antibiotics. Persons with UTIs often have urine with a pungent odor. Further evaluation of patients with glomerular and nonglomerular hematuria should include determination of renal function and 24-hour urinary protein or spot urinary protein-creatinine ratio. Urinalysis is invaluable in the diagnosis of urologic conditions such as calculi, urinary tract infection (UTI), and malignancy. Its dipped into your urine, and the chemicals on the stick react and change color if levels are above normal. If the acid is abnormal, you could have, Glucose. Computed tomographic urography is the preferred imaging modality for the evaluation of patients with asymptomatic microscopic hematuria. Treat with 14 days of ciprofloxacin, and tailor further antibiotic therapy according to culture results. If ketone levels are high, they may need treatment in the hospital, with: Some low-carb diets can cause the body to break down fat and produce ketones for fuel. Urinalysis can be used to detect certain diseases, such as diabetes, gout, and other metabolic disorders, as well as kidney disease.It can also be used to uncover evidence of drug abuse. It is characterized by an inability to produce enough insulin or use the hormone insulin properly, which causes blood sugar levels to be abnormally high. Quiz, Electrolytes in Urine: Normal Lab Values and Causes of Change Type 1 diabetes usually develops in childhood or teenage years., Type 2 diabetes. Although the urinalysis results are consistent with a urinary tract infection, the clinical history suggests asymptomatic bacteriuria. Urinary tract infection. The strips change color if a substance is present at a level that is above normal. Your support helps families facing kidney, Tests to Measure Kidney Function, Damage and Detect Abnormalities. Quiz, Crystals in Urine: Meaning and Causes All rights reserved. Ketonuria most commonly is associated with uncontrolled diabetes, but it also can occur during pregnancy, carbohydrate-free diets, and starvation. A complete urinalysis includes physical, chemical, and microscopic examinations. A patient is taking a nephrotoxic drug. In lupus treatment, a urinalysis is often used to monitor protein leakage and identify and assess urinary tract infections (UTIs). Refer him to a urologist for evaluation of a complicated urinary tract infection. Finally, although computed tomography would detect a ureteral stent, it is not preferred over radiography because it exposes the patient to unnecessary radiation. The predominant cellular elements determine the type of cast: hyaline, erythrocyte, leukocyte, epithelial, granular, waxy, fatty, or broad (Figure 3). The best results come from using whats known as the clean catch method. He reports that he often has strong-smelling urine, but has no dysuria, urge incontinence, fever, or suprapubic pain. Things the dipstick test can check for include: If urinalysis is the only test youre having, you should be able to eat and drink normally before the procedure. The presence of renal tubule cells indicates significant renal pathology (Figure 2). Further evaluation of persistent proteinuria usually includes determination of 24-hour urinary protein excretion or spot urinary protein-creatinine ratio, microscopic examination of the urinary sediment, urinary protein electrophoresis, and assessment of renal function.32. a "fruity" or acetone smell on the breath frequent urination thirst dry or flushed skin difficulty breathing confusion abdominal pain nausea and vomiting high blood sugar levels In severe cases, a. Bono, M. J., & Reygaert, W. C. (2018). Urologic causes of hematuria include tumors, calculi, and infections. ) A urinalysis reveals that the patient's urine contains glucose, hemoglobin, and white blood cells (pus). Diabetic ketoacidosis can cause urine to have a fruity or sweet odor, and alkaline fermentation can cause an ammoniacal odor after prolonged bladder retention.

Which of the following should be considered first? A urine test can detect various substances, including glucose, ketones, protein, bacteria, and bilirubin. Urinary pH can range from 4.5 to 8 but normally is slightly acidic (i.e., 5.5 to 6.5) because of metabolic activity. Guidelines from the American Urological Association were also reviewed. It is usually given at your healthcare provider's office, but there are also at-home test kits available. Protein in the urine can be a sign of kidney disease. E. Perform urine cytology to evaluate for bladder cancer. An infection may make urine look cloudy. You might also have this test regularly if you have a condition such as a kidney disease that needs to be watched over time. Asymptomatic bacteriuria is the isolation of bacteria in an appropriately collected urine specimen obtained from a person without symptoms of a urinary tract infection.12 The presence of bacteria in the urine after prolonged catheterization has been well described; one study of 605 consecutive weekly urine specimens from 20 chronically catheterized patients found that 98% contained high concentrations of bacteria, and 77% were polymicrobial.13, Similar results have been reported in patients who perform clean intermittent catheterization; another study of 1,413 urine cultures obtained from 407 patients undergoing clean intermittent catheterization found that 50.6% contained bacteria.14 Guidelines from the Infectious Diseases Society of America recommend against treatment of asymptomatic bacteriuria in nonpregnant patients with spinal cord injury who are undergoing clean intermittent catheterization or in those using a chronic indwelling catheter.12. We avoid using tertiary references.

Unconjugated bilirubin is water insoluble and cannot pass through the glomerulus; conjugated bilirubin is water soluble and indicates further evaluation for liver dysfunction and biliary obstruction when it is detected in the urine. Erythrocytes are best visualized under high-power magnification. A person with diabetes who finds ketones in their urine needs to seek medical advice to prevent the problem from getting worse. If a person finds ketones in their urine, they should ask their doctor for advice. Acidity, or pH. Diabetes influences what a person eats and how they live their life. A urinalysis is also called a "urine test." Conditions with problems using or making the hormone insulin, Conditions with the kidney where the tubules are damaged, or other kidney defects, Eating more sugars than the body can process at once, Your baby grows too big, and you need a C section, Risk of heart disease and type 2 diabetes after your pregnancy is over, Anti-glucagon-like peptide-1 receptor antagonists. B. It can help find problems that need treatment, including infections or kidney problems. Liman, M., Jialal, I., Physiology, Glycosuria, StatPearls Publishing, 2021. Without treatment, this can lead to complications, such as a kidney infection. This content is owned by the AAFP. Organisms such as Chlamydia and Ureaplasma urealyticum should be considered in patients with pyuria and negative cultures. Our website is not intended to be a substitute for professional medical advice, diagnosis, or treatment. Casts in the urinary sediment may be used to localize disease to a specific location in the genitourinary tract (Table 6).38 Casts, which are a coagulum of Tamm-Horsfall mucoprotein and the trapped contents of tubule lumen, originate from the distal convoluted tubule or collecting duct during periods of urinary concentration or stasis, or when urinary pH is very low. Although urinalysis is not recommended as a routine screening tool except in women who may be pregnant, physicians should know how to interpret urinalysis results correctly. According to the American Urological Association, the presence of three or more red blood cells (RBCs) per high-powered field (HPF) in two of three urine samples is the generally accepted definition of hematuria.1820 The dipstick test for blood detects the peroxidase activity of erythrocytes. This material may not otherwise be downloaded, copied, printed, stored, transmitted or reproduced in any medium, whether now known or later invented, except as authorized in writing by the AAFP. In the absence of symptoms of a urinary tract infection or nephrolithiasis, there is no need to culture the urine, treat with antibiotics, refer to a urologist, or perform imaging of the abdomen and pelvis. In these assessments you'll be tested on: To learn more about sugar's effects on the body, have a look at the accompanying lesson titled Glucose Levels in Blood and Urine. Uncomplicated urinary tract infections diagnosed by positive leukocyte esterase and nitrite tests can be treated without culture. In this type, your body becomes resistant to insulin and doesnt respond to the hormone, which causes problems using glucose. Gram staining can help guide antibiotic therapy, but it is not indicated in routine outpatient practice. A patient's urinalysis reveals the presence of glucose. An early sign of diabetic nephropathy is protein in the urine. This test is specific but not highly sensitive. In the short-term, uncontrolled high blood sugar levels can lead to symptoms such as thirst, a need to urinate often, and an increased risk of DKA. Chronically high blood sugar levels are toxic to your blood vessels, causing them to narrow and become more clogged over time. It occurs in 0.5 to 1 percent of all DKA cases, 36, 37 and carries a mortality rate of 21 to 24 percent. Other names for it are urine test, urine analysis, and UA. Tubular reabsorption of glucose is via active transport, thus requiring energy, and is done in response to balance the glucose in the body. A doctor may test for protein in the urine to monitor for kidney problems. A urine glucose test is an indirect measure of your blood sugar (glucose) levels. A urinalysis is a simple test that looks at a small sample of your urine. Therefore, detecting glucose in the urine may be both a sign and a reminder to regulate your blood glucose levels more tightly. You will need to do this a specific amount of time after dipping the strip in the urine. This phenomenon occurs because the ureteral stent bypasses the normal nonrefluxing uretero-vesical junction, resulting in transmission of pressure to the renal pelvis with voiding. A urinalysis is also called a urine test.. Type 2 diabetes usually appears later in life and takes years to develop. As your kidneys get less blood, the filtration mechanism that removes waste and reabsorbs vital nutrients becomes damaged. The procedure is slightly different if a person already has a diagnosis of diabetes and is conducting a urine test at home. , Diabetes causes glycosuria because there either isnt enough insulin, or your body cant use what's available. Urinalysis is one way to find certain illnesses in their earlier stages. Do health insurance policies cover urine glucose tests? It's dipped into your urine, and the chemicals on the stick react and change color if levels are above normal. Home tests are similar to these. Everything You Need to Know About Blood Sugar Tests, 6 Blood-Sugar Friendly Foods to Eat During Diabetes Awareness Month. Retained ureteral stents may become encrusted, and resultant stone formation may lead to obstruction.10. Here are the steps: For babies and other people unable to provide a sample this way, a doctor may have to insert a soft, narrow tube called a catheter through the urinary opening and into the bladder. See how one patient learned to manage her weight and diet. . Often, lifestyle measures such as a healthful diet and exercise are key to reducing the risks of further complications. Simple steps to prevent diabetes. This situation initially results in alkaline urine, but as the filtered load of bicarbonate decreases, the urine becomes more acidic. ", University of Utah Eccles Health Sciences Library: "Urinalysis. All Rights Reserved. A 33-year-old woman with a history of nephrolithiasis presents with a four-week history of urinary frequency, urgency, urge incontinence, and dysuria. A more recent article on office-based urinalysis is available. After one week of exposure, one third of strips give false-positive results, and after two weeks, three fourths give false-positive results.36 Non-nitratereducing organisms also may cause false-negative results, and patients who consume a low-nitrate diet may have false-negative results. [ corrected] Under high-powered magnification, gram-negative rods, streptococci, and staphylococci can be distinguished by their characteristic appearance. Under normal circumstances, insulin shuttles glucose from the bloodstream into the cells to be used for energy or stored as fat, but this does not happen in diabetes. A urinalysis can test for high levels of ketones and glucose in your child's urine, both signs of diabetes. It is dipped into the urine. If you are diagnosed with diabetes, take comfort in the fact that it is a very treatable and manageable condition. For example, if your results are only slightly abnormal and you dont have any other symptoms of an illness, your doctor may not do other tests. A. Visual exam. At least 10 million Americans suffer from incontinence, which means that they are not able to control the times when they urinate. However, when a person has diabetes, glucose can pass from the kidneys into the urine. Can diet help improve depression symptoms? These crystals are colorless and have a characteristic coffin lid appearance. Urine must be refrigerated if it cannot be examined promptly; delays of more than two hours between collection and examination often cause unreliable results.2. Flank discomfort and recent history of urinary tract manipulation suggest that this is not an uncomplicated urinary tract infection; therefore, a three-day course of antibiotics is inadequate. The supernatant then is decanted and the sediment resuspended in the remaining liquid.37 A single drop is transferred to a clean glass slide, and a cover slip is applied. Glycosuria occurs when the filtered load of glucose exceeds the ability of the tubule to reabsorb it (i.e., 180 to 200 mg per dL). The next steps depend on why you had the test in the first place. However, it will likely involve a color strip and a reference chart for checking the levels of ketones, proteins, or glucose in the urine. MNT is the registered trade mark of Healthline Media. A midstream clean-catch technique usually is adequate in men and women. Numbness and tingling in the hands or feet, Eating a healthy, low carb diet tailored to your glucose and dietary needs, Taking your medication as prescribed, especially. A urinalysis (also known as a urine test) is a test that examines the visual, chemical and microscopic aspects of your urine (pee). B. Insulin is a hormone that regulates how much glucose is in your blood., Type 1 diabetes. The chronic kidney injury that is sustained is called diabetic kidney disease. Results of her urinalysis with microscopy are shown in Table 4. Before an operation to screen for problems. Urinary specific gravity (USG) correlates with urine osmolality and gives important insight into the patients hydration status. There are three main causes of glycosuria:, Diabetes, called diabetes mellitus, is a condition where your body cant make enough insulin or use insulin properly. The patient is eating too many carbohydrates B. High glucose levels can make your urine cloudy. Treatment of asymptomatic bacteriuria is not recommended in nonpregnant adults, including those with prolonged urinary catheter use. Your body needs a lot of energy as your baby grows, but sometimes it cant keep up with demand and doesn't make enough insulin., Without the insulin, you will have too high sugar levels, and it will show up in your urine.. This content is owned by the AAFP. Because results of repeat urinalysis after 48 to 72 hours should be negative in patients with this condition, extended testing is not warranted. The urine will be looked at for color and clearness. A urinalysis is a test of your urine. ", Urology Care Foundation: "What is a Urinalysis? Specific gravity provides a reliable assessment of the patients hydration status. 2023 Dotdash Media, Inc. All rights reserved, Verywell Health uses only high-quality sources, including peer-reviewed studies, to support the facts within our articles. Blood may make urine look red or the color of tea or cola. A strong odor may be the result of a concentrated specimen rather than a urinary tract infection. Blood tests reveal a serum glucose level of 325 mg/dL and serum creatinine of 0.8 mg/dL. You will receive your score and answers at the end. Harvard School of Public Health. is a paper strip with patches impregnated with chemicals that undergo a color change when certain constituents of the urine are present or in a certain concentration. A urinalysis is just one piece of information about whats going on in your body. A. Once filtered, lowmolecular-weight proteins are reabsorbed and metabolized by the proximal tubule cells. In the long-term, it can lead to widespread damage throughout the body and a wide range of conditions, such as cardiovascular disease. When glucose levels are too high, the kidneys excrete the excess amount in the urine. Normal urinary proteins include albumin, serum globulins, and proteins secreted by the nephron. Other causes of abnormal odors include gastrointestinal-bladder fistulas (associated with a fecal smell), cystine decomposition (associated with a sulfuric smell), and medications and diet (e.g., asparagus). This article will discuss how this test is used, what to do to prepare, and how to assess your results and manage your diagnosis. He reports increased frequency of urination and nocturia, but does not have gross hematuria. Quiz, Measuring Blood Oxygen Levels High blood sugar levels during pregnancy can cause problems for you and your baby: Your doctor might do in-office urine tests at your regular prenatal visits to check for glycosuria. It is unwise to assume that benign prostatic hyperplasia is the explanation for hematuria, particularly because patients with this condition typically have risk factors for malignancy. Be sure to let your doctor know about all the medicines you take, including over-the-counter drugs, vitamins, and supplements. Approximately 80% of patients with a ureteral stent experience stent-related pain that affects their daily activities.11. To ensure reliability, check that the test strips have not expired and follow the directions carefully. Visualization of intact erythrocytes on microscopic examination of the urinary sediment can distinguish hematuria from other conditions. Which metabolic disorder would explain the results, and how does the glucose physically "spill over" into the urine? A person viewing it online may make one printout of the material and may use that printout only for his or her personal, non-commercial reference. Copyright 2023 American Academy of Family Physicians. It is a rare condition that develops when a person's blood sugar levels are normal, but the kidneys are unable to retain glucose.. D. Inform him that his enlarged prostate is causing microscopic hematuria, and that he can follow up as needed. 38 Cerebral edema predominantly. What is the urinary tract? Results of a 24-hour urine analysis are as follows: Total volume = 5L Total glucose = 375 g Total creatinine = 2.4 g Urobilinogen is reabsorbed into the portal circulation, and a small amount eventually is filtered by the glomerulus. In the absence of obvious causes, the evaluation of microscopic hematuria should include renal function testing, urinary tract imaging, and cystoscopy. High ketone levels can be dangerous, and may lead to ketoacidosis. Alkaline urine in a patient with a UTI suggests the presence of a urea-splitting organism, which may be associated with magnesium-ammonium phosphate crystals and can form staghorn calculi. In overflow proteinuria, lowmolecular-weight proteins overwhelm the ability of the tubules to reabsorb filtered proteins. Microscopic hematuria is common and has a broad differential diagnosis, ranging from completely benign causes to potentially invasive malignancy. The test results will identify the levels of glucose, ketones, and protein in the urine. What is an appropriate description to share with family members of the patient? If ketone levels rise too far, they can cause the blood to become too acidic. A microscopic exam checks for things too small to be seen otherwise. The patient's blood will be purified for 24 hours. Some of the things a dipstick examination can check for include: A urinalysis can help to detect many diseases before you feel symptoms. Still, you should take your medications as you normally would unless your healthcare provider advises otherwise. The onset of symptoms in those with type 2 diabetes is more gradual and usually occurs in adulthood. The presence of a ureteral stent causes mucosal irritation and inflammation; thus, findings of leukocyte esterase with white and red blood cells are not diagnostic for urinary tract infection, and a urine culture is required. If your urine glucose tests come back indicating elevated glucose levels, it's natural to be alarmed, but the mere presence of glucose in the urine does not mean you have diabetes. As a result, the body starts to break down fat to use for energy instead. Although flank pain and urinalysis suggest possible pyelonephritis, this patient should not be treated for simple pyelonephritis in the absence of radiography to identify a stent. A metabolic stone workup may be useful for prevention of future kidney stones, but it is not indicated in the acute setting. A person with diabetes should speak to their doctor if they notice the following symptoms: People with kidney disease often do not notice any symptoms until the later stages, when the kidneys no longer work effectively. Cloudy urine often is a result of precipitated phosphate crystals in alkaline urine, but pyuria also can be the cause. It can also help find serious diseases in the early stages, like kidney disease, diabetes, or liver disease. If the pH of the urine is high, this can indicate the presence of certain bacteria. Learn more here about diabetic kidney disease. Yes. Quiz, Amylase and Pancreatic Lipase: Causes & Associated Conditions Although urine cytology is typically part of the urologic workup, it should be performed at the time of cystoscopy; the AUA does not recommend urine cytology as the initial test.5, After ureteroscopy with lithotripsy, a ureteral stent is often placed to maintain adequate urinary drainage.10 The stent has one coil that lies in the bladder and another that lies in the renal pelvis. This can reveal the type of bacteria present and gives an idea of which treatment to prescribe. Although prior cleansing of the external genitalia often is recommended in women, it has no proven benefit. A diagnosis of prediabetes will enable a person to make lifestyle changes that can slow or reverse the progress of the condition. glucosuria) is. In a person with diabetes, this can lead to diabetic ketoacidosis (DKA), a potentially fatal condition that needs emergency treatment. Urinalysis and Kidney Disease: What You Need to Know. Results of repeat urinalysis after 48 to 72 hours should be negative in patients with this condition.30. Too much glucose can damage your organs and nerves, but your body does need enough sugar for energy.. It may also show presence of protein, ketones, bacteria, and/or casts. The noncontrast-enhanced phase is optimal for detecting stones in the urinary tract; the nephrographic phase is useful for detecting renal masses, such as renal cell carcinoma; and the delayed phase outlines the collecting system of the urinary tract and can help detect urothelial malignancies of the upper urinary tract.9 Although the delayed phase can detect some bladder masses, it should not replace cystoscopy in the evaluation for bladder malignancy.9 After a negative microscopic hematuria workup, the patient should continue to be followed with yearly urinalysis until at least two consecutive normal results are obtained.5, In patients with microscopic hematuria, repeating urinalysis in six months or treating empirically with antibiotics could delay treatment of potentially curable diseases. In most cases, it is necessary to compare the color of the strip against a color chart. All rights reserved. If a doctor finds high levels of glucose, ketones, or protein in a persons urine, they may order further tests. WebMD does not provide medical advice, diagnosis or treatment. Exercise-induced hematuria is a relatively common, self-limited, and benign condition. A dipstick is a thin, plastic stick with strips of chemicals on it. If ketone levels are high, seek medical help at once to prevent further problems developing. Dipstick urinalysis is convenient, but false-positive and false-negative results can occur. The presence of transitional epithelial cells is normal. In a patient with a ureteral stent, urinalysis alone cannot establish the diagnosis of urinary tract infection. Those who use insulin or other medications may need to monitor for low blood sugar. A urine glucose test detects and measures this excess sugar, a condition called glycosuria. Marsden, J., & Pickering, D. (2015). Results of his urinalysis with microscopy are shown in Table 5. How reliable are home testing kits? Many gram-negative and some gram-positive organisms are capable of this conversion, and a positive dipstick nitrite test indicates that these organisms are present in significant numbers (i.e., more than 10,000 per mL). Urinalysis results yield routine clinical information necessary for everyday diagnoses localized to the renal and urologic systems; findings such as pyuria indicative of cystitis or hematuria related to renal calculi are some commonplace examples. The excess of glucose produced by the insulinoma impairs the exit of glucose out of the cell leading to decreased levels of glucose in the blood. It is important to note that urine tests will not indicate whether blood glucose levels are too low. Hemolysis and hepatocellular disease can elevate urobilinogen levels, and antibiotic use and bile duct obstruction can decrease urobilinogen levels. If a urine test identifies glucose, a doctor will usually carry out an or A1C, or glycated hemoglobin (HbA1c) blood test to determine if a person has diabetes.
