WebSep 1, 2024 · The cycle threshold or Ct value of a RT-PCR reaction is the number of cycles at which fluorescence of the PCR product is detectable over and above the background signal. Many PCR assays use 40 as cut off for Ct value to consider the test positive, allowing detection of even very few starting RNA molecules [4].
