Which sequence correctly explains a midstream urine collection to a patient?

• A. Practice includes cleansing the genital area with soap and water, then collect after starting urination, and deliver within 4 hours.
• B. Wash hands, remove lid, cleanse genital area and begin urination, during urination collect sample, finish, and deliver to lab within 2 hours or refrigerate until delivery.
• C. Don gloves, collect midstream sample after voiding completely, deliver to lab within 24 hours at room temperature.
• D. Collect sample after prior alcohol intake; store in freezer.

Answer: (B)

Collecting a midstream clean-catch urine sample requires a sequence that minimizes contamination from skin and the urethra and keeps the specimen usable for testing. Start with good hand hygiene and preparing the collection container, then cleanse the genital area to reduce surface contaminants. Begin urinating, and collect the urine that comes midstream—this avoids the initial flow that carries bacteria from the urethral opening—then finish urinating and securely cap the container. Transport the sample to the lab promptly, ideally within 2 hours, or refrigerate if delivery will be delayed. This timing and sequence help preserve sample quality and accuracy of test results. Collecting after voiding completely, using inappropriate storage like freezing, or delaying transport beyond recommended windows would increase contamination or alter the specimen, making it less reliable.
