Reported risk: 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.
