It&#8217;s used to detect and manage a wide range of disorders, such as urinary tract infections, kidney disease and diabetes.<\/p>\n<p>A urinalysis involves checking the appearance, concentration and content of urine. For example, a urinary tract infection can make urine look cloudy instead of clear. Increased levels of protein in urine can be a sign of kidney disease.<\/p>\n<p>Unusual urinalysis results often require more testing to find the source of the problem.<\/p>\n<p>A urinalysis is a common test that&#8217;s done for several reasons:<\/p>\n<ul>\n<li><strong>To check your overall health.<\/strong> A urinalysis might be part of a routine medical exam, pregnancy checkup or pre-surgery preparation. Or it might be used to screen for a variety of disorders, such as diabetes, kidney disease or liver disease, when you&#8217;re admitted to a hospital.<\/li>\n<li><strong>To diagnose a medical condition.<\/strong> A urinalysis might be requested if you have abdominal pain, back pain, frequent or painful urination, blood in your urine, or other urinary problems. A urinalysis can help diagnose the cause of these signs and symptoms.<\/li>\n<li><strong>To monitor a medical condition.<\/strong> If you&#8217;ve been diagnosed with a medical condition, such as kidney disease or a urinary tract infection, your doctor might recommend testing your urine regularly to monitor your condition and treatment.<\/li>\n<\/ul>\n<p>Other tests, such as pregnancy testing and drug screenings, might rely on a urine sample, but these tests look for substances that aren&#8217;t included in a typical urinalysis.<\/p>\n<p>If you&#8217;re having only a urinalysis, you can eat and drink before the test. If you&#8217;re having other tests, you might need to fast before the test. Your health care provider will give you specific instructions.<\/p>\n<p>Many drugs, including nonprescription medications and supplements, can affect the results of a urinalysis. Before a urinalysis, tell your doctor about medications, vitamins or other supplements you take.<\/p>\n<p>You might collect a urine sample at home or at your health care provider&#8217;s office. Providers typically give out containers for urine samples. You might be asked to collect the sample at home first thing in the morning, when your urine is more concentrated.<\/p>\n<p>You might be instructed to collect the sample midstream, using a clean-catch method. This method involves the following steps:<\/p>\n<ul>\n<li>Cleanse the urinary opening. Women should spread the labia and clean from front to back. Men should wipe the tip of the penis.<\/li>\n<li>Begin to urinate into the toilet.<\/li>\n<li>Pass the collection container into your urine stream.<\/li>\n<li>Urinate at least 1 to 2 ounces (30 to 60 milliliters) into the collection container.<\/li>\n<li>Finish urinating into the toilet.<\/li>\n<li>Deliver the sample as directed by your health care provider.<\/li>\n<li>If you can&#8217;t deliver the sample to the designated area within 60 minutes of collection, refrigerate the sample, unless your provider has told you otherwise.<\/li>\n<\/ul>\n<p>In some cases, if needed, your provider can insert a thin, flexible tube (catheter) through the urinary tract opening and into the bladder to collect the urine sample.<\/p>\n<p>The urine sample is sent to a lab for analysis. You can return to your usual activities immediately.<\/p>\n<p>For a urinalysis, your urine sample is evaluated in three ways: visual exam, dipstick test and microscopic exam.<\/p>\n<h3>Visual exam<\/h3>\n<p>A lab technician examines the urine&#8217;s appearance. Urine is typically clear. Cloudiness or an unusual odor can indicate a problem, such as an infection. Protein in urine can make it appear foamy.<\/p>\n<p>Blood in the urine can make it look red or brown. Urine color can be influenced by what you&#8217;ve just eaten or by certain drugs you&#8217;re taking. For example, beets or rhubarb might tint your urine red.<\/p>\n<h3>Dipstick test<\/h3>\n<p>A dipstick &mdash; a thin, plastic stick with strips of chemicals on it &mdash; is placed in the urine. The chemical strips change color if certain substances are present or if their levels are above typical levels. A dipstick test checks for:<\/p>\n<ul>\n<li><strong>Acidity (pH).<\/strong> Der <abbr title=\"acidity\">pH<\/abbr> level indicates the amount of acid in urine. The <abbr title=\"acidity\">pH<\/abbr> level might indicate a kidney or urinary tract disorder.<\/li>\n<li><strong>Concentration.<\/strong> A measure of concentration shows how concentrated the particles are in your urine. A higher than normal concentration often is a result of not drinking enough fluids.<\/li>\n<li><strong>Protein.<\/strong> Low levels of protein in urine are typical. Small increases in protein in urine usually aren&#8217;t a cause for concern, but larger amounts might indicate a kidney problem.<\/li>\n<li><strong>Sugar.<\/strong> The amount of sugar (glucose) in urine is typically too low to be detected. Any detection of sugar on this test usually calls for follow-up testing for diabetes.<\/li>\n<li><strong>Ketones.<\/strong> As with sugar, any amount of ketones detected in your urine could be a sign of diabetes and requires follow-up testing.<\/li>\n<li><strong>Bilirubin.<\/strong> Bilirubin is a product of red blood cell breakdown. Usually, bilirubin is carried in the blood and passes into your liver, where it&#8217;s removed and becomes part of bile. Bilirubin in your urine might indicate liver damage or disease.<\/li>\n<li><strong>Evidence of infection.<\/strong> Either nitrites or leukocyte esterase &mdash; a product of white blood cells &mdash; in your urine might indicate a urinary tract infection.<\/li>\n<li><strong>Blood.<\/strong> Blood in your urine requires additional testing. It may be a sign of kidney damage, infection, kidney or bladder stones, kidney or bladder cancer, or blood disorders.<\/li>\n<\/ul>\n<h3>Microscopic exam<\/h3>\n<p>Sometimes performed as part of a urinalysis, this test involves viewing drops of concentrated urine &mdash; urine that&#8217;s been spun in a machine &mdash; under a microscope. If any of the following levels are above average, you might need more tests:<\/p>\n<ul>\n<li><strong>White blood cells<\/strong> (leukocytes) might be a sign of an infection.<\/li>\n<li><strong>Red blood cells<\/strong> (erythrocytes) might be a sign of kidney disease, a blood disorder or another underlying medical condition, such as bladder cancer.<\/li>\n<li><strong>Bacteria, yeast or parasites<\/strong> can indicate an infection.<\/li>\n<li><strong>Casts<\/strong> &mdash; tube-shaped proteins &mdash; can be a result of kidney disorders.<\/li>\n<li><strong>Crystals<\/strong> that form from chemicals in urine might be a sign of kidney stones.<\/li>\n<\/ul>\n<p>A urinalysis alone usually doesn&#8217;t provide a definite diagnosis. Depending on the reason your provider recommended this test, you might need follow-up for unusual results. Evaluation of the urinalysis results with other tests can help your provider determine next steps.<\/p>\n<p>Getting standard test results from a urinalysis doesn&#8217;t guarantee that you&#8217;re not ill. It might be too early to detect disease or your urine could be too diluted. Tell your provider if you still have signs and symptoms.<\/p>\n<p>For specifics about what your urinalysis results mean, talk with your health care provider.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>This common lab test checks urine for signs of disease and for clues about overall health.<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","template":"","tags":[1686,1687,1682],"class_list":["post-52908","mayo","type-mayo","status-publish","hentry","tag-anatomical-structure","tag-medical-procedure","tag-person-group-concept","content_type-tests-procedures"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.6 -
