Why is it important to track reagent lot numbers and quarantine old lots until acceptance when a new lot is introduced?

Tracking reagent lot numbers and quarantining old lots until acceptance are safeguards to ensure assay accuracy and patient safety. Different production lots can vary slightly, and those small differences can shift calibration or control results. When a new lot arrives, you verify it with calibration materials and controls to confirm it still produces results within the established performance range. Revalidating the lot’s performance helps catch any drift or bias before it affects patient results. Keeping a record of every lot number provides traceability. If a QC issue arises or a recall is needed, you can pinpoint exactly which tests were run with a specific lot and respond quickly. Quarantining old lots until the new lot passes acceptance criteria prevents the use of unverified reagents, ensuring that only validated materials enter routine testing. In short, lot tracking, thorough verification with calibration and controls, revalidation of performance, and withholding unaccepted lots together maintain consistency, reliability, and safety in laboratory results.
