What is the third step in the drug testing process?

• A. Review PSV-35 with the client
• B. Preparation - For swab, instruct client to have no food or drink within 10 minutes of testing
• C. Sign out of UA/Swab container and label with client's name and SID
• D. Preparation - For UA cup-collection, client must be properly instructed to wash hands, roll up sleeves and place primary and secondary clothing to the floor

Answer: (C)

This item tests the proper sequencing and chain-of-custody steps in a drug testing workflow. After the specimen is collected, the next essential action is to sign out of the UA/Swab container and label it with the client's name and SID. Signing out creates a formal record that the specific container belongs to that client and links it to their unique identifier, making it ready to move to the lab or storage only after verification. This labeling prevents mix-ups, ensures accountability, and preserves the sample’s integrity during transport and testing.

The other actions occur earlier in the process: reviewing PSV-35 with the client is typically done to orient or inform before or during collection, not after; and preparation steps for swab or urine cup collection are instructions given before collection to ensure the client is ready, not after. Hence, signing out and labeling is the correct third step because it directly follows collection and establishes traceability and accountability before the sample proceeds.
