WHAT IT IS
The COVID-19 IgG/IgM antibody test is an in-vitro qualitative rapid immunochromatographic test registered with the Ministry of Health for the differential detection of SARS-CoV-2 IgG and IgM antibodies in human serum, plasma, or whole blood samples collected via finger prick.
It is designed to help determine recent or previous exposure to SARS-CoV-2 virus, thereby monitoring the patient’s disease status after SARS-CoV-2 infection.
HOW IT WORKS
Capillary whole blood samples may be collected with a finger-prick system. Serum, plasma, or whole blood samples can be taken via venous sampling, according to the facility’s normal procedures.
The sample is placed in the top sample well area on the test device. After approximately 20 seconds, two drops of buffer solution are added to the well, after which the bands may appear.
ADVANTAGES AND BENEFITS
The rapid antibody test is used to detect the presence or absence of antibodies in the blood produced in response to infection. It may thus be used to map the spread of the epidemic in the population.
This type of test is based on a simple blood draw and the results are ready in 15 minutes.
WHAT TO DO IF
A positive result does not necessarily indicate a current infection; it represents a different stage of the disease after infection. Positive IgM or positive IgM / IgG both suggest recent exposure, while positive IgG suggests previous or latent infection. Current infection should be confirmed through RT-PCR, to detect SARS-CoV-2 RNA.
