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 WebApr 6, 2024 · The CT value is a marker of the viral load in a patient, potentially suggesting the severity of the COVID-19 infection. The lower the CT value, the higher the severity. A patient is considered COVID-19 negative if the CT value is 35 in the RT-PCR test. If the CT value is below 35 in the RT-PCR test, a patient is a COVID-19 positive.
