What is this test?

This is a qualitative urine test, meaning it reports whether a particular substance was detected rather than providing a measured amount. The abbreviated code does not clearly identify the substance being tested.

Why might I need this test?

A urine test may be ordered to help evaluate urinary symptoms, screen for a substance, or investigate a laboratory or kidney-related concern. The reason depends on the specific substance named in the full test order.

How is the test performed?

A urine sample is collected and examined in the laboratory, often with a reagent strip or another laboratory method. The method varies with the substance being tested and may produce a detected, not detected, or similar result.

How do I prepare for the test?

Unless your clinician provides different instructions, a clean-catch midstream urine sample is usually requested. Follow any stated timing, fasting, or container requirements, and avoid urine collected during heavy bleeding or shortly after urination.
