Why This Test Is Done

Your healthcare provider may order this test if they suspect kidney issues, metabolic disorders, or conditions affecting phenylglycine metabolism. It can also be part of a broader evaluation for inherited metabolic diseases or monitoring long-term kidney health.

What to Expect Before the Test

You’ll typically collect all urine for 24 hours, starting and ending with your first morning urine. Store the sample at room temperature or refrigerate if needed. Follow your provider’s instructions carefully to ensure accurate results.

What the Test Involves

After collecting your urine sample, it will be sent to a lab for analysis. The test measures the rate of phenylglycine metabolites in your urine, often using a specialized biochemical method.

What the Results Mean

Results may indicate normal metabolism, kidney function, or potential abnormalities in phenylglycine processing. Your provider will interpret the results in the context of your overall health and medical history.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Clinical significance: Elevated or abnormal levels may suggest kidney dysfunction, metabolic disorders, or conditions like phenylketonuria (PKU) or other inherited metabolic diseases. Low levels might indicate improper excretion or metabolic issues.
