Descrizione
How much protein in urine is normal ?
• The protein urine dipstick test measures the presence of proteins, such as albumin, in a urine sample.
• Albumin and protein can also be measured using a blood test.
• After you provide a urine sample, it is tested.
• The health care provider uses a dipstick made with a color-sensitive pad.
• The color change on the dipstick tells the provider the level of protein in your urine.
• If needed, your provider may ask you to collect your urine at home over 24 hours.
• Your provider will tell you how to do this.
• Follow instructions exactly so that the results are accurate.
• Different medicines can change the result of this test.
• Before the test, tell your provider which medicines you are taking.
• DO NOT stop taking any medicine before talking to your provider.
• The following may also interfere with test results:
• Dehydration: Dye (contrast media) if you have a radiology scan within 3 days before the urine test. Strenuous exercise, Urinary tract infection, Urine contaminated with fluids from the vagina, How the Test Will Feel
• The test only involves normal urination. There is no discomfort.
• This test is most often done when your provider suspects you have kidney disease. It may be used as a screening test.
• Although small amounts of protein are normally in urine, a routine dipstick test may not detect them.
• A urine microalbumin test can be performed to detect small amounts of albumin in the urine that may not be detected on dipstick testing.
• If the kidney is diseased, proteins may be detected on a dipstick test, even if blood protein levels are normal.
• For a random urine sample, normal values are 0 to 20 mg/dL.
• For a 24-hour urine collection, the normal value is less than 80 mg per 24 hours.
• The examples above are common measurements for results of these tests.
• Normal value ranges may vary slightly among different laboratories.
• Some labs use different measurements or test different samples.
• Talk to your provider about the meaning of your specific test results.
