Coronavirus Antibody Test
WHEN SHOULD YOU PERFORM THE ANTIBODY TEST?
This test is not suitable to be performed in the early illness because it can give false negative results. It takes your body time to produce antibodies. The best time to do the test is 3 to 4 weeks from the initial onset of symptoms. However, the earliest time can be 14 days after the initial onset of symptoms
Symptoms of coronavirus include: new and persistent dry cough, sore throat, shortness of breath, fever, muscle aches, and sometimes, diarrhoea.
If you have had a cough and flu-like illness since the outbreak of COVID-19, but have now recovered and are asymptomatic, this test has the potential to find out whether you have already had COVID-19.
No clinical test is always 100% accurate. However, when this test is performed at the right time it can give a very useful indication of whether an individual has been exposed to SARS-CoV-2 or not.
HOW ACCURATE IS THE TEST?
Please bear in mind that this new form of testing has been limited verified in a laboratory setting and the efficacy of this test is therefore is not 100% clear.
A recent published study found a sensitivity of 100% and a Specificity of 99,90%, The company itself provides the information about a 100% Specificity and 97,50 Sensitivity.
INTERPRETATION OF RESULTS
So-called cross reactions with proteins from other coronavirus types cannot be completely excluded. That means, that there is a slight chance that antibodies, which the body has developed against a different Coronavirus type and not SARS-CoV-2, could be found.
A negative result means that no Covid-19 antibodies have been detected.
You’ve either not had an infection with SARS-CoV-2 or your body has not developed a sufficient immune response to develop antibodies.
A positive Result for IgG antibodies indicates a later stage of infection likely with SARS-CoV-2.
To date, it is still not clear if antibodies give you immunity and if so, how long this immunity will last. Because the disease is new, there is an ongoing debate about if and for how long individuals with antibodies are protected.
