The urine collection method in which the initial urine is discarded and the midstream is collected is known as

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

Answer: (C)

The key idea is reducing contamination to get a representative sample of bladder urine. By discarding the initial urine, you flush out bacteria and cells from the urethra and surrounding skin, so the portion collected in the middle better reflects what’s in the bladder. This specific approach is known as a midstream catch. It’s often described in practice as a clean-catch because you clean the area first, but the action described—collecting the urine that comes after the initial flow—is exactly the midstream portion. The other options either focus on the first part (which is more likely to be contaminated) or describe a non-timed or broad sampling method, so they don’t fit the scenario as precisely.
