To put this record in context, PlainRecalls indexes 83,949 recalls across the FDA, CPSC, NHTSA and USDA FSIS going back to 1995. Within the same product category, the database holds 6 closely related recalls, of which 6 were also issued by FDA Devices. That clustering is a signal — repeated actions in a narrow category often indicate a systemic quality-control issue, a supplier-wide contamination, or a design defect that has propagated across product lines. This recall is roughly 4 years old; older recalls can remain relevant because many units enter resale, rental, and secondary-market channels where the original warning never reaches the end user. Always cross-check the recall number against the official agency page before relying on any summary.

Product Description

GREER M. FAENI, 0.25 mL 20 MG/ML, Item: K6, Analyte Specific Reagent, HYPERSENSITIVITY PNEUMONITIS test system, gel diffusion kit for demonstrating precipitating antibodies.

Reason for Recall

The product was recalled because stability evaluation of the lots indicated a decrease in reactivity that could lead to a potential false-negative result interpretation. The issue was identified by the firm after failing to meet lot requirements for potency. The lot release error was discovered on October 08, 2021, after a failed potency test was determined during 6-month stability evaluation of retention material for the lots. The subsequent manufacturing investigation, which included a review of the lot release potency documentation, found that the initial lot release potency test for the lot was misinterpreted.
