Manufacturer 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.
FDA Determined

Device Design
Action On May 13, 2021, Quidel issued an Urgent Medical Device Correction notice to customers via email notifying them that Quidel has determined that there is a potential for patients with high SARS CoV 2 viral loads to be falsely interpreted as negative if target amplification occurs prior to a cycle threshold (Ct) value of 5 when using specified applications. YOU NEED TO TAKE THE FOLLOWING ACTIONS: 1. Immediately review the revised Lyra SARS CoV 2 Assay Instructions for Use (IFU) for updated Result Interpretation guidance: https://www.fda.gov/media/136820/download. 2. For clinical specimens generating Ct values d5, perform 1:10 and 1:100 dilutions using uninoculated transport media, extract, and test the diluted samples according to the Lyra SARS CoV 2 IFU. Refer to the Lyra SARS CoV 2 Assay IFU for full, detailed instructions. 3. It is recommended that any data which has been previously generated be re-evaluated and samples re-tested, as needed. 4. Complete the enclosed Field Corrective Action Fax Back form acknowledging receipt and understanding of the recommended actions.
