Limits of RT-PCT for COVID-19

The real-time PCT (RT-PCR) test seeking the COVID-19 specific virus suffers from some inherent drawbacks such as 1) limitation of good sample patients (recent study tells that the upper respiratory sample has 30% sensitivity), 2) the need for specially trained technicians and equipped certified labs to run the test, and 3) high level of need in resources, e.g. cost and time.

Moreover, it has been reported that many COVID-19 virus-shedding patients are asymptomatic or have very few symptoms, and the period of virus shedding starts very early and stays so long, even when the virus titer is quite low.

'SGTi-flex COVID-19 IgM&IgG' is a serological (blood) rapid test.

'SGTi-flex COVID-19 IgM&IgG' detects the presence of COVID-19 specific lgM & lgG antibodies, which are specific proteins made within days after infection, even in patients that don't have symptoms. The antibodies detected by this test indicate that a person had an immune response to COVID-19, whether symptoms developed from infection or the infection was asymptomatic. Antibody test results are important in detecting infections with few or no symptoms. It covers the entire course of infection and improves the overall diagnosis of COVID-19 in acute phases of illness.

It is very important to diagnose COVID-19 to defend against the expansion of COVID-19. 'SGTi-flex COVID-19 IgM/IgG' helps communities to identify infection and isolate people without symptoms but suspected to be infected by COVID-19.
