The box at right indicates a … ( 6 ) Dipstick Test Chemical testing usually involves inserting a thin strip of plastic known as a dipstick into the urine sample. Normal Urine Protein Levels. The NTx test can measure N-telopeptide levels in the urine or blood. A patient's urine test values should be interpreted based on the reference value of the laboratory in which the test was done; the laboratory typically provides these values with the test result. The acidity of urine varies greatly depending on a person’s diet and any medical conditions they may have. Persistent protein in the urine is an early sign of chronic kidney disease. A positive nitrite test is a surrogate marker of bacteruria. Normal Urinalysis Results and Interpretation of Abnormal Results … Some nonspecific crystals may be seen in urine as a result of the urine sample not being freshly analyzed (within 1-2 hours), being kept at a cold temperature, or from acidic (low pH) urine. A urine albumin result of 30 milligrams per gram (mg/g) or less is normal. Normal Laboratory Values: Urine Reference values vary based on several factors, including the specific laboratory that supplies them. The normal range of protein for a random urine sample: 0 to 8 mg/dL; The normal value of protein for a 24-hour urine collection: Less than 150 mg per 24 hours. So what is considered normal for a urine test? Over-the-counter urine dipsticks typically have between two and 10 chemical test squares, which may include pH, specific gravity, leukocytes, nitrites, protein, glucose, ketones, urobilinogen, bilirubin and blood. Normal Concentration results: specific gravity: 1.025 to 1.032 Osmolality: >800 mOsm/kg. Microalbuminuria: This is a sensitive test that can detect a small amount of protein in the urine. If you do not receive a normal result, it usually means that you have an underlying illness or disease. Albumin is a protein found in the blood. Anything higher than this may be a sign of kidney disease. Small amounts of crystals in the urine may be normal in healthy people. The test involves checking the concentration, appearance, and content of urine. Clinical urine tests are examinations of the physical and chemical properties of urine and its microscopic appearance to aid in medical diagnosis. While a certain amount of bone breakdown is perfectly normal, a high rate of bone breakdown suggests that there may be long-term bone loss and, in time, a greater risk for fracture. A damaged kidney lets some albumin pass into the urine. What is urine albumin? Normal urine should range in color from clear to dark yellow. Normal Dilution Test results: specific gravity: 1.0003 Osmolality: 100 mOsm/kg. Positive test strongly suggests infection but negative test does not exclude it (PPV 95% and NPV 25 – 70 %). A simple test can be done to detect protein in your urine. Nitrates in the urine are converted to nitrites in the presence of Gram‐negative bacteria such as E.coli and Klebsiella. A doctor can help you interpret the results properly. A urine albumin result above 30 may mean kidney disease. A healthy kidney does not let albumin pass into the urine. A urine albumin result below 30 is normal. The normal protein levels in urine may vary slightly from lab to lab. Sometimes crystals can be seen in the urine under the microscope. The less albumin in your urine… The results of each test are interpreted as normal or possibly abnormal.
