Factors associated with cycle threshold values (Ct-values) of SARS-CoV2-rRT-PCR.

Background: Presented work studies the association of COVID-19 severity, patient demographics, and clinical history with cycle threshold (Ct) values of SARS CoV2-rRT-PCR. We studied the Ct values for Orf1ab, N, and RdRp genes in association with all the factors mentioned above.

Methods And Results: We examined the individuals (n = 6331) that consulted two private diagnostic centers for COVID-19 testing.
