Abstract:
The SARS-CoV-2 pandemic persists with all its virulence despite 650,382,819 doses of COVID vaccine worldwide. The reference test for infection identification is reverse transcription polymerase chain reaction (RT-qPCR). The usefulness of this test may be diminished by simplifying its result as positive or negative. Determining the number of cycles (Ct) in positive RT-qPCR tests can assist in decision-making when interpreted in the clinical context of patients.

Real-time reverse transcription-polymerase chain reaction, or Real-time RT-PCR, is an analytical tool used to determine the expression level of target genes. The method involves converting mRNA to complementary DNA with the help of an enzyme known as reverse transcriptase, followed by the PCR amplification of the cDNA. These two processes can be performed simultaneously in a single tube or separately as a two-step reaction.
