The majority of patients who recover from Coronavirus have been found to produce antibodies; initially an IgM antibody and then an IgG antibody during the recovery phase. The detection IgG antibody shows whether a person has previously been infected by SARS-Cov-2. This test detects both the IgG and the IgM antibodies.
The blood test should be booked for 17 days or more following exposure or onset of symptoms. The immune system reacts to the SARS Cov-2 by producing antibodies from a few days to 2 weeks and beyond. Specific IgG antibodies are produced at the later stages of the infection to SARS Cov-2. The persistence of IgG antibodies allows the identification of people who have been infected by SARS -Cov-2.
Medical tests are usually measured for accuracy by looking at two criteria – Specificity and Sensitivity. The higher the percentage, the more accurate the result.
The test is 100% Specific.
A test that has 100% specificity will identify 100% of patients who do not have the disease.
The test is 97.5 % Sensitive.
A test that is 100% sensitive will identify all patients who have the disease.
