Abstract:This study aimed to determine if the crossing point of the initial positive SARS-CoV-2 PCR test correlated with patient demographics, subsequent hospitalization, or duration of positivity. Seventy-three patients with two or more positive PCR tests had a median time of 23 days to two consecutive negative results.
Keywords:SARS-CoV-2  COVID-19  Molecular testing  Duration of positivity  Crossing point (Cp)
