What should be included in the "Remarks" section to avoid a fatal flaw when a specimen is cold or blue?

When addressing the "Remarks" section in a situation where a specimen is cold or blue, it's essential to include detailed information that provides context for any issues related to the specimen's integrity. Including a reference to a second specimen helps validate the testing process and confirms that the collector followed appropriate protocols. This is particularly important because the condition of a specimen can raise questions about its validity and testing reliability.

By documenting the existence of a second specimen, the collector ensures that there is a backup for verification, which mitigates concerns stemming from the primary specimen's condition. This inclusion serves as a safeguard against potential disputes or uncertainties in the testing results. It creates a more comprehensive record that supports the overall quality and credibility of the testing process.

In contrast, while temperature entry and specimen type are also important details to document, they do not provide the same level of context in mitigating the implications of the cold or blue condition. The collector's signature is crucial for authentication but does not specifically address the issues related to the specimen's state. Thus, the inclusion of the second specimen reference is the most effective way to avoid a fatal flaw in this scenario.
