What is the proper technique for a clean catch specimen?

• A. Wipe from front to back
• B. Wipe from back to front
• C. Wipe in circles outward
• D. Do not wipe

Answer: (A)

Cleansing the genital area before a clean catch aims to minimize bacteria that could contaminate the urine sample. The best technique is to wipe from front to back, moving from the urethral opening toward the anus. This direction reduces the chance of pushing rectal bacteria toward the urethra and into the sample. Wiping from back to front could drag bacteria toward the urethral opening, increasing contamination. Wiping in circles outward doesn’t reliably reduce contamination, and not wiping at all leaves skin bacteria and debris that can ruin the specimen. Following the front-to-back method helps ensure the sample reflects urinary tract content rather than surrounding skin bacteria.
