How many signatories are required on the laboratory report?

• A. 2
• B. 3
• C. 4
• D. 5

Answer: (B)

The requirement reflects a process of full verification and authorization: an analyst signs to confirm the test was performed correctly, a supervisor signs to attest that the data and interpretation were reviewed and validated, and a certifying official such as the laboratory director signs to authorize the release of the report. This three-signature structure ensures accountability, accuracy, and compliance with regulatory expectations, so the report carries authenticated responsibility from execution through final release. Having only two signs would omit an essential level of verification or certification, while more than three adds unnecessary redundancy and potential confusion about roles.
