Recall Insight

This FDA Devices action (record #Z-1928-2021) was formally reported on July 7, 2021, with the manufacturer initiating the action on April 27, 2021. It is classified under Critical severity (Class I), with a current status of Terminated. Quidel Corporation is listed as the recalling firm, operating out of Athens, OH. Federal records indicate 29,787 kits (96 results/kit) units are affected, placing this recall in the million-unit bracket that typically triggers nationwide consumer alerts and retailer sweeps.

The documented reason for this recall is: In rare situations patients infected with high viral load of SARS CoV 2 may have samples that generate Ct values less than or equal to (d) 5 when certain amplification and detection platforms (thermocyclers) are used. T… Distribution data in the federal record shows the product reached: Worldwide distribution - US Nationwide distribution in the states of AL, CA, CT, DC, FL, ID, IN, MA, MI, MO, NM, NY, OH, SC, TN, TX, WA and the countries of Canada, Saudi Arabia, United Kingdom.. Distribution scope directly affects the consumer exposure window and determines whether a recall remains regional or escalates into a nationwide advisory.

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 5 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

Lyra SARS-CoV-2 Assay (M120) in vitro diagnostic test reagent

Reason for Recall

In rare situations patients infected with high viral load of SARS CoV 2 may have samples that generate Ct values less than or equal to (d) 5 when certain amplification and detection platforms (thermocyclers) are used. These specimens would be falsely interpreted as negative if target amplification occurs prior to a cycle threshold (Ct) value of 5. There have been no formal complaints of False Negative results with Ct values <5 from Lyra SARS-CoV-2 Assay users.
