Test Preparation For Optimal Results:
A clean catch is recommended when completing a urine collection. Before producing the urine sample, drink plenty of fluids prior to the test. When giving the sample, allow 1-2 seconds of urine to flow before catching it in the sample container given to you at the lab. If possible, have the lab collected early in the morning or shortly after waking. For comparison purposes, have subsequent labs collected close to the same time.
Disclaimer: A health care provider should evaluate a deviation from normal ranges.
