COV6 (Abbott Realtime), COV8 (Alinity Singleplex), COV10 (Cepheid rapid respiratory panel), Cepheid SinglePlex E and N2 Ct, and COV12 (Alinity Resp-4-Plex respiratory panel) cycle threshold to genome copies/mL conversions. Warning, conversions are approximate; there may be significant variability in specimen collection that also should be considered, and Ct values may not take into account specimen-specific amplification inhibition which may artifactually increase Ct values.
