Lyra SARS-CoV-2 Assay (M120) by Quidel: Class I Recall - Due to Risk of False Negative Results
Company Announcement
Quidel is recalling the Lyra SARS-CoV-2 Assay (M120) due to a significant risk of false negative results for patients with relatively high amounts of SARS‐CoV‐2 virus potentially causing the PCR amplification to occur before a cycle‐threshold (Ct) value of ≤5 when using the following thermocyclers:
- ThermoFisher QuantStudio 7 Pro
- Applied Biosystems 7500 Fast Dx
- Applied Biosystems 7500
- Bio-Rad CFX96 Touch
- Roche LightCycler 480 or
- Qiagen RotorGene MDx)
False negative results may lead to delayed diagnosis or inappropriate treatment of SARS-CoV-2 that may cause patient harm, serious illness, and death. False negative results can also lead to further spread of the SARS-CoV-2 virus, when presumed negative patients are introduced into groups within health care, long-term care, or other similar facilities. Actions to limit exposure based on false negative results might not be taken, such as isolating infected individuals.
Quidel has received five complaints about the Lyra SARS-CoV-2 Assay (M120), however, there have been no reports of injuries or death from this issue.
