WebCycle threshold (Ct) is a numerical value generated during a RT -PCR test. It refers to the number of cycles needed for a sample to amplify and cross a threshold (cut-off) to be considered detected/positive. Most RT-PCR tests use Ct cutoffs of 35 -40 cycles, so any sample with a Ct value below the cutoff, would be considered a true WebAlthough an exact copy number cannot be calculated, it is generally considered that a C value ≥35 represents a very low viral titer (<100 genome copies). The xGen™ SARS-CoV-2 Amplicon Panel used with the xGen Amplicon Core Kit and indexing primers supports a wide range of inputs/C values.
