The main concept is preventing contamination in a clean-catch midstream urine sample through proper hygiene, preparation, and collection technique. The correct approach starts with thorough hand hygiene and cleansing of the urethral area from front to back to reduce introducing bacteria from skin or surrounding areas. Open the sterile container without touching its inner surface so the inside remains uncontaminated. Begin urinating into the toilet and then, without stopping the flow, collect the midstream portion directly into the container, which minimizes initial and trailing contaminants from the urethra or genital area. Finally, seal the container tightly to keep the sample closed and preserve its cleanliness.

Rinsing the container with water or starting collection before touching the container can introduce microbes or contaminate the sample, and waiting to collect after holding urine for several seconds does not ensure midstream collection.
