The LIONRUN Diagnostic Kit for Antibody IgM/IgG of Novel Coronavirus COVID-19 is an in vitro diagnostic test for the qualitative and differential detection of IgM and IgG antibodies against the 2019 novel Coronavirus (2019-nCoV) also known as Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) in human whole blood, serum or plasma.
This test detects the presence of COVID-19 antibodies (IgM/IgG) in blood samples. As there may be a few days' delay between the viral infection and development of antibodies in an individual, any negative result from this test should not be used as sole basis to rule out COVID-19 infection. The negative results have to be carefully considered together with clinical presentations. Any positive result from this test should be confirmed with supplemental laboratory testing (e.g. RTPCR).
IgM
Appear on day 1-7 of an acute infection. Detection of IgM in blood indicates a recent infection. it can be used as early screening for Novel CoV suspected population.
IgG
In the mid to late stage of infection B lymphhocytes enter lymph node and transform into plasma cells and produce large amount of IgG. Detection of IgG indicate on-going or past infection, useful in the monitoring of progress of infection.
