A COVID-19 antibody test is a simple blood test that determines whether you have already had coronavirus, or not.

Unlike the PCR test which can determine whether you have coronavirus now, the antibody test examines a small finger prick blood sample to look for specific antibodies produced by the immune system in response to a recent infection, usually within 7 to 14 days after you experience symptoms.

When a person contracts a viral infection, a toxin, or a foreign substance known as an antigen, enters the body (in this case, the COVID-19 virus). The immune system then produces antibodies to fight those antigens, and will store specific memory cells so that if and when a person comes into contact with that antigen again, the memory cells work quickly to produce the correct antibodies to fight it.*

AlphaBiolabs offers a rapid and highly accurate antibody test for coronavirus and COVID-19 infections. Our test is an internationally recognised, IgM-IgG Combined Antibody Rapid Test.

How does the AlphaBiolabs COVID-19 antibody test work?

During viral infections, the antibody ‘immunoglobulin M’ (IgM) is the first antibody to respond to an initial exposure, usually within 21 days. The immune system’s secondary response is to generate ‘immunoglobulin G’ (IgG), which is the most common type of antibody found in blood.

The AlphaBiolabs coronavirus antibody test screens for both COVID-19-specific IgM and IgG antibodies.

The test also provides vital information about the stage of infection. Detection of IgM antibodies indicates a recent exposure to COVID-19, whereas detection of IgG antibodies indicates a later stage of infection. It can therefore help an individual get clearer on, a) do I currently have coronavirus, and b) have I already had coronavirus?

This level of knowledge is vital in the fight against COVID-19, for example it can help companies re-open their workplaces whilst ensuring their workforce is protected, it can also help individuals in their daily interactions with family members and friends.**

The test is simple to carry out with minimal discomfort. There are four easy steps which include, 1) collecting the finger prick blood sample, 2) add the blood sample to the sample well on the testing device, 3) add 2-3 drops of the buffer solution to the separate buffer well, and 4) see your results after 15 minutes.
