Why is expiration monitoring of reagents critical in automated systems, and how is it enforced?

Expiration monitoring is essential because reagents can degrade or lose potency over time, leading to changes in assay performance and potentially inaccurate patient results. In automated systems, this is enforced through integrated inventory control that records each reagent’s lot number and expiration date, software-driven alerts as a reagent approaches its expiry, and lockout or disablement features that prevent the system from using any expired lot. This combination keeps testing reliable, reduces the risk of erroneous results, and supports quality assurance processes.
