A 25-year-old woman has been instructed to provide a midstream clean catch urine sample for a urinalysis. When explaining the procedure, which of the following is the essential step the medical assistant should emphasize to ensure the sample is not contaminated?
Clean the sample container with soap and water before use
Urinate a small amount into the toilet before catching the midstream urine in the container
Fill the container to the top to ensure there is enough urine for testing
Hold the container at least six inches away from the body to avoid splashback
The correct answer is to begin urination into the toilet before catching the midstream urine in the container. This step ensures that the initial stream, which might contain contaminants from the external urethral orifice, is voided before the rest of the urine is collected midstream, which is typically less contaminated and more suitable for accurate urinalysis.
