The Enzyme-Linked Immunosorbent Assays (ELISAs) based test is used for the detection of antibodies that are produced by the body to fight against antigens or foreign substances.
How is it carried out?
The ELISA-based test is a blood test with high sensitivity and specificity.
1. This test draws from the face.
2. The sample is then added to the small holes of the ELISA plate.
3. This plaque is coated with antigen or an inactivated form of the virus.
4. If the blood contains antibodies, the blood will bind to the antigen and a substrate solution is added to the well.
5. The reaction usually results in a color change, which detects antibodies. To know more about ELISA, you can also visit www.bosterbio.com/human-app-picokine-trade-elisa-kit-ek0658-boster.html.

What is IgG?
Immunoglobulin G (IgG) is an antibody.
The body produces immunoglobulin M (IgM) and IgG antibodies to fight pathogens.
1. IgM antibodies are produced four to seven days after the pathogen enters the body.
2. IgG antibodies are produced between 10 and 14 days after the pathogen appears. If IgG antibodies are detected, SARS-CoV-2 exposure can be inferred.
ELISA is also a form of the rapid test. However, other rapid antibody tests are suitable for breastfeeding and use the finger prick method of drawing blood. They take less time and do not require a laboratory process to detect antibodies.
ELISA-based and on-site tests are for monitoring purposes only.
