What is the term for the maximum time blood can be held before testing?

The term that refers to the maximum time blood can be held before testing is "Sample holding time." This term specifically addresses the duration that a specimen can be maintained in a stable state prior to analysis, ensuring that the integrity of the sample remains intact for accurate testing results. Sample holding time is critical in laboratory procedures, as it encompasses various factors like temperature and preservation methods that can affect the viability of the sample.

For clarity on the other terms: "Storage time" typically refers to the duration a sample can be stored under controlled conditions, which may not necessarily align with the maximal holding period for pre-testing stability. "Turnaround time" usually defines the interval between sample collection and the reporting of results but does not indicate how long the sample can be held before testing. "Expiration time" is often used related to the end date for the usability of a sample, but it does not precisely capture the concept of maximum pre-testing duration as effectively as sample holding time does.
