How do you assess specimen integrity beyond temperature checks?

• A. Check only the label.
• B. Inspect volume, appearance, container integrity, seal status, and look for unusual color, turbidity, or odor that could indicate tampering.
• C. Rely on staff assumption.
• D. Only rely on electronic chain-of-custody.

Answer: (D)

Beyond temperature checks, you verify specimen integrity by a thorough physical and visual check of both the sample and its container. This means confirming the volume is appropriate, examining the sample’s appearance for any unusual color, turbidity, or odor, and inspecting the container for cracks, leaks, or seal failures. Look closely at the seal status to ensure tamper-evident features are intact. These steps help detect tampering, contamination, or dilution that temperature alone cannot reveal. Electronic chain-of-custody is important for showing who handled the specimen, but it cannot by itself prove that the sample hasn’t been compromised. It should accompany these physical checks, not replace them. Why the other approaches fall short: checking only the label misses any tampering or quality issues; relying on staff assumption ignores objective indicators; and relying solely on electronic records ignores the tangible signs of integrity issues that physical inspection can reveal.
