What is the approved method for washing hands during collection?

• A. Soap and water
• B. Water only
• C. Alcohol-based sanitizer
• D. No washing

Answer: (B)

Hand hygiene during collection aims to remove dirt without introducing substances that could affect the specimen or its analysis. Washing with water only cleans effectively while avoiding residues from soap or alcohol-based cleaners that might contaminate the sample or interfere with testing. If hands are visibly dirty or the protocol calls for it, a soap-and-water wash may be used, but in this context the goal is a minimal-residue clean, which water alone provides. Alcohol-based sanitizer can leave residues or interact with sampling materials, so it isn’t the approved method here. Not washing at all would increase contamination risk, so water-only washing strikes the right balance for this procedure.
