The urine collection method that minimizes contamination by collecting during midstream is called

• A. First-void collection
• B. Clean-catch
• C. Random sample
• D. Midstream catch

Answer: (D)

Midstream catch focuses on obtaining urine from the middle portion of the flow. By starting to void, letting the initial urine wash out any bacteria from the distal urethra or surrounding skin, and then collecting the sample, you minimize contamination. This yields a sample that more accurately reflects the urine from the bladder for culture and analysis. First-void collection captures the beginning of the stream and is more prone to contamination; a random sample has no control for contamination; clean-catch involves cleaning the area and often collecting midstream urine, but the method that specifically describes collecting during midstream is midstream catch.
