Detection of antibodies against Covid-19 virus infection and immune response by high sensitivity immunoassay (ELISA) from venous blood. The Vircell COVID-19 IgM + IgA and IgG tests can detect with high confidence whether IgM + IgA and IgG antibodies can be detected in your body after a virus infection.
The test is performed by ELISA.
The SARS-CoV-2 IgM + IgA determined value for acute, recent infection can be detected.
The SARS-CoV-2 IgG assay is suitable for detecting an immune response to an infection that has already occurred, which also indicates protection against the virus. SARS-CoV-2 IgM test indicates viral infection 2-3 days after PCR detectability. The SARS-CoV-2 IgG test is suitable for detecting the onset of infection at least 14 days after infection.
An additional benefit of the SARS-CoV-2 IgM + IgA and IgG test is the lower test fee.
How sampling is done?
We take venous blood from you aseptically using a blood sampling method. The results of the test will be sent to you electronically within 5 days.
How to interpret the test results?
Positive IgM + IgA result IgM + IgA immune response against SARS-CoV-2 can be detected in your body. The
infection was present at the time of sampling or in the few days prior to sampling. In case of a positive result, it is also recommended to perform another confirmatory test to confirm the existing disease, like SARS-CoV2 PCR test.
A positive IgM + IgA result with 99% confidence means that the individual's symptoms are caused by
COVID-19 infection.
Positive IgG result
The presence of IgG antibodies allows the identification of previously infected patients who have already recovered from the disease and are likely to become immune to it. It is also possible to screen out individuals who have had an
asymptomatic infection and are likely to have developed immunity. At present, there is not much data on the duration of acquired immunity, serological tests should be performed periodically after the first positive result.
Negative IgM + IgA and negative IgG results
A negative IgM + IgA and IgG result means that your body does not have a detectable amount of antibodies against the SARS-CoV2 virus.
There are several reasons for this:
– you are not infected
– you are infected, but the infection is still latent, when the tested antibodies are not
yet produced by your immune system
– you are infected but are at an early stage of the infection when IgM + IgA and IgG
antibodies have not yet been detectable.
The results of laboratory tests should always be interpreted in the context of clinical symptoms and epidemiological data when making decisions about final diagnosis and treatment of the individual. In order to make an accurate diagnosis, it is advisable to discuss your previously observed symptoms in detail with your doctor and to determine the time window of suspected infection.
Results around the detection threshold
Rarely, but for all such methods, a there is transition period when the tests do not give a clear positive or negative result. This is called a detection threshold. In such a case, an amount of immunoglobulin can be measured in the patient that does not qualify for any of the endpoints. In this case, it is appropriate to repeat the study within 4-7 days.
Pursuant to the EMMI Regulation (1/2014), the health care provider must report the results of the performed laboratory tests together with the personal identification data of the examined person to the central epidemiological system (OSZIR) in case of both positive and negative results.
