How do you interpret kidney function test results?


Quick Answer

Doctors use standardized ranges to interpret the glomerular filtration rate and the urine albumin test results that indicate kidney health, according to the National Kidney Disease Education Program. A normal glomerular filtration rate is 60 mls/min/1.73m2 or higher. Patients with kidney disease have a glomerular filtration rate lower than 60 mls/min/1.73m2, while a result lower than 15 mls/min/1.73m2 indicates possible kidney failure. A score of 30 or more on a urine albumin test also indicates possible kidney disease.

The glomerular filtration rate test is a blood test that measures how quickly the blood passes through the glomeruli, explains MedlinePlus. The glomeruli act as filters for the body's blood and remove waste from the bloodstream.

A glomerular filtration rate of over 90 mls/min/1.73m2 is normal unless a doctor detects another symptom of chronic kidney disease, notes The Renal Association. A glomerular filtration rate of 60 to 90 mls/min/1.73m2 indicates possible chronic kidney disease, but a doctor must find other symptoms of chronic kidney disease to make that diagnosis. Below 60 mls/min/1.73m2 indicates a definite problem with kidney function.

A urine albumin test measures the amount of a specific blood protein that the kidneys allow into the body's urine, according to the National Kidney Disease Education Program. A healthy kidney prevents most of this protein transfer. Sometimes a doctor takes a patient's blood pressure as part of a kidney function test, notes the National Kidney Disease Education Program. Maintaining healthy blood pressure helps protect good kidney function.
