Solve any doubts you might have with these Covid ANTIBODY Test kit FAQs
ANTIBODYCOVID is the only antigen antibody test that measures the three specific levels of the most important immunoglobulin for the body’s immunisation against COVID. That’s why this test works and it’s the most accurate and reliable test on the market. The extremely accurate ANTIBODY Covid-19 test measures the number of antibodies you have with the greatest accuracy, establishing your level of protection against COVID-19 with only a blood sample needed.
COVID-19 is an infectious disease caused by a virus, a coronavirus that was only recently discovered. For most people who get COVID-19 the symptoms of the virus are those of a light to moderate respiratory illness and most people recover without needing any special treatment. Older people or people with underlying health problems are more likely to develop a serious illness.
(IgG1 +, IgA +, IgM +) – A positive result for any of the three immunoglobulins indicates that there are antibodies against SARS CoV-2 protein S in the sample and therefore that you have been infected with this virus in any of its variants (symptomatically or asymptomatically), or that you have been vaccinated and that you have potentially protective antibodies in your blood.
(IgG1-, IgA-, IgM-) – A negative result for all three immunoglobulins indicates that there are NO antibodies against SARS-CoV-2 protein S in the sample and therefore that you have NOT passed the infection with this virus in any of its variants, or that the infection or vaccination (in the case of been vaccinated) have not generated sufficient humoral immunity to be detected by this technique.
(IgG1 +, IgA +, IgM-) – A positive result for IgG1 and IgA but negative for IgM would indicate that you were infected with the virus or were vaccinated a long time ago and that you have potentially protective antibodies in your blood. A presence of IgA anti-S would indicate that you possibly have this type of antibody in the mucous membranes of the respiratory system and that you have a first protective barrier against infection.
(IgG1 +, IgA-, IgM-). – A positive result for IgG1 but negative for IgA and IgM would indicate that you were infected with the virus or were vaccinated and that you have potentially protective antibodies in your blood.
(IgG1-, IgA-, IgM +) -If you have antibodies of the IgM type and not IgG1 or IgA, you are probably passing the infection, have had it very recently or have recently been vaccinated. If it had been more than a month since the infection or since the second dose of the vaccine and you have IgM but not IgG1 or IgA, these results would indicate that your immunity is not complete.
(IgG1-, IgA + IgM-) – If you have antibodies of the IgA type and not IgG1 or IgM, you are probably passing the infection, have had it very recently or have been vaccinated recently. If it had been more than a month since the infection or since the second dose of the vaccine and you had IgA but not IgG1 or IgM, these results would indicate that your immunity is not complete.
Positive: the test result is compatible with the presence of IgG1, IgM and/or IgA antibodies against the Spike protein (protein S) from SARS-CoV-2 in the sample tested.
Negative: the test result is compatible with the absence of IgG1, IgM and/or IgA antibodies against the Spike protein (protein S) from SARS-CoV-2 in the sample tested.
Ratio: This value quantifies the amount of immunoglobulin of each type (if detectable) in arbitrary units of measure. The positivity ranges for each immunoglobulin are expressed in parentheses. In the case of IgG1, it is indicated if the value is low (0.001-3 AMU), medium (3.001-5 AUM), high (5.001-10 AMU) or very high (more than 10 AMU).
IgG1 is the most abundant form of IgG in serum. It is a very important immunoglobulin in mediating antibody responses against viral infections. It has neutralising capacity against SARS-CoV-2 (ability to bind complement and also to bind with high affinity to Fc receptors on immune system cells such as macrophages and NK cells) and can activate the destruction of virus-infected cells. IgA is an immunoglobulin found in abundance in the mucosal lining fluids of the nose, pharynx, bronchi and lungs, making it a first barrier in the neutralisation of viruses entering via the airborne route. IgM provides the first protection in response to infection. It is able to activate the destruction of infected cells, however, it is a low affinity immunoglobulin, i.e. it does not bind very strongly to viruses and is weak in its neutralising capacity.
