Specific antibody response to SARS‐CoV‐2. The incubation period of COVID‐19 is relatively long and has been reported to be 5‐10 d. A specific IgM response is the early antibody response that starts and peaks within 7 d. IgM continues as long as the acute phase of the disease continues. Specific IgA and IgG antibodies develop several days after IgM and do not decrease to undetectable levels and are assumed to continue lifelong as protective antibodies. This research requires an international consensus on the usage of correct methodology and antigens of SARS‐CoV‐2
