COVID-19 diagnostic facts and figures
COVID-19 serological markers dynamics (Total Ab/ IgM/ IgG)
20%-40% of the patients developed antibodies on days 0-7 after onset
60%~70% of the patients developed antibodies on days 8-11 after onset
> 90% of the patients had detectable levels of antibodies starting from day 12 after onset.
COVID-19 molecular markers dynamics (RNA)
RNA was detected in 60-75% of the patients on days 0-8 after onset
RNA levels decrease to 40-50% starting from day 9 after onset
COVID-19 combined serological and molecular markers increases the sensitivity of
diagnosis while maintaining the high specificity. Among the serological markers, total Ab detection has greater significance in clinical practice.
