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 WebThe CT ratio is the ratio of primary current input to secondary current output at full load. For example, a CT with a ratio of 300:5 is rated for 300 primary amps at full load …
