High cycle threshold
WebCycle threshold Ct (cycle threshold) values represent the number of cycles of amplification elapsed before the test system signals detection of the target. In general terms, the higher the Ct value the lower the quantity of virus target (viral load) present in the sample. Precise definition of what constitutes a high Ct value is difficult WebAs our coauthor Jamieson et al 1 demonstrated, a positive result with a cycle threshold (C T) value >35 may indicate as little as one organism per sample and likely represents …
