Why Get Tested?

To screen for excess protein in the urine, to help evaluate and monitor kidney function, and to detect kidney damage

When to Get Tested?

As part of a routine physical, as a follow-up to a previous positive urine protein test, or when you have a disorder or disease that affects the kidney

Sample Required?

A single urine sample collected at any time (random) or 24-hour urine sample; occasionally, a split 24-hour sample, with the night collection (11pm to 7am) separated from the day collection (7am to 11pm). Often, a blood sample may also be taken to measure your creatinine and serum protein levels, especially when a 24-hour urine has been ordered.
