WebCT value refers to the number of cycles needed for the PCR machine to determine a positive result. The test focuses on 3 genes which are: E, N and RdRP and confirms a person has been infected by the COVID-19 virus. For an RT-PCR test, the process requires a temperature cycling reaction called the amplification cycle. WebLow Ct values (high viral load) more likely indicate acute disease and high infectivity. High Ct values (low viral load) can be attributed to several clinical scenarios whereby the …
