What is a clean-catch urine specimen?
A clean-catch urine specimen is a small amount of urine that has been caught in a cup. First, the urethral opening (where the urine comes out) is carefully cleaned to make sure the urine does not pick up any bacteria that may be around the opening as the infection leaves the body. Learn how to collect a clean-catch specimen. Important: Follow the “clean-catch” instructions carefully. The urine specimen you provide must not contain skin debris, soap, or other material that may be near your urethra (the opening for urine outflow).
