Module: Quality Systems

Subject: Vendor Recall

Question 1

The laboratory receives notification that a reagent/standard that they have purchased has been recalled by the manufacturer. How should they proceed?

An investigation should involve the QAO, purchasing staff, lab director and analysts. Contact the vendor for details about the recall.  Determine if the reagent is actually in use, and if so, how long has the lab been using the reagent?  Then identify which batches the reagent was used in and how many samples were affected? If possible, determine whether there was any negative impact. If there is a potential negative impact notify analysts at the bench to cease using the product.  A work stoppage may be set in place until the lab is sure it is not using the recalled reagent/standard. Initiate a Corrective Action/non-conformance report.

Notify customers, clients of any potential issues impacting analytical results.

Find alternative source of reagents / standards, re-run samples with good reagents / standards if possible and if needed use a subcontract if needed for re-analysis.  Re-evaluate vendor suitability if needed, and consider more closely monitoring future purchases. Cancel scheduled analyses/tests if needed.  Re-evaluate and potentially revise reports.  Recall data if warranted.
