Specimen Requirements

Preparation of Patient: 

Laboratory recommends a midstream "clean-catch" random urine collection.  See patient instructions female/male.  Follow physician's instructions if they differ from laboratory recommendation.

1. Patient should cleanse urethral area with wipes provided then pass a small amount of urine into the toilet and then stop.

2. At that point, then pass urine into a cup; half full is preferred.
