How should samples be transported to the laboratory?

• A. Air-dried in unlabeled bags and mailed to the lab.
• B. Sealed, tamper-evident containers with chain-of-custody forms; maintain sample integrity and avoid cross-contamination.
• C. Containers that are opaque but not sealed, with no chain-of-custody.
• D. Refrigerated containers without labeling.

Answer: (B)

Keeping the transport process secure and traceable is essential. Samples must be shipped in sealed, tamper-evident containers to prevent leakage, contamination, or tampering during transit. Pairing this with chain-of-custody forms creates a documented trail of every person who handles the sample, ensuring accountability and regulatory defensibility. This approach helps preserve the sample’s original condition and minimizes the risk of cross-contamination or misidentification. Temperature control may be necessary for some analyses, but without proper sealing and a clear chain of custody, the integrity and credibility of the results can be compromised. The other options fail because they lack proper sealing, labeling, or traceability, which are crucial for preserving sample integrity and ensuring accurate lab results.
