The body’s immune system produces antibodies - proteins that are critical for fighting and clearing out the virus.
SARS CoV 2 is an enveloped, single-stranded RNA virus of the family Coronaviridae, genus Beta coronaviruses.
SARS CoV 2 is transmitted person-to-person primarily via respiratory droplets, but also indirect transmission through contaminated surfaces is possible.
SARS CoV 2 can be isolated from respiratory samples obtained via nasopharyngeal/ oropharyngeal swabs or from sputum. The coronavirus accesses host cells via the angiotensin-converting enzyme 2 (ACE2), which is the most abundant in the lungs.
The incubation period for coronavirus is thought to range from 2 to 14 days following exposure, with most cases showing symptoms approximately 4 to 5 days after exposure.
Definite COVID 19 diagnosis entails SARS CoV 2 detection by RT PCR method
Anti SARS CoV 2 Test is an immunoassay test for the qualitative detection of antibodies (including IgG) to Severe Acute Respiratory Syndrome Coronavirus 2 (SARS CoV 2).
Seroconversion or recovery is observed after a median of 10 to 13 days after symptom onset for IgM and 12-14 days for IgG and lasts for several months. Levels and chronological order of IgM and IgG antibody appearance are highly variable supporting detection of both antibodies simultaneously.
