Stool collection procedure requires which of the following?

Stool collection procedure requires which of the following?

• A. Collect in the morning only
• B. Avoid urine contamination and collect according to provider instructions
• C. Collect using a sterile needle from the vein
• D. Collect only during the day

Answer: (B)

A stool collection must be free of urine contamination and follow provider instructions to ensure the specimen is accurate and usable. Urine can introduce substances that alter test results or interfere with analysis, leading to unreliable findings. Following the provider’s instructions covers how much stool to collect, which container to use, whether any preservative or refrigeration is needed, and how to label and transport the sample, all of which help maintain specimen integrity. The other options aren’t correct because stool is collected from a bowel movement, not by a needle from the vein, and there’s no universal requirement to collect only in the morning or only during the day.
