Antibodies are produced in the body in response to infection
Antibodies develop in most people within two to three weeks after the onset of symptoms. People who have been infected by COVID-19, caused by coronaviruses, can be asymptomatic or only experience mild to moderate symptoms. COVID-19 can be detected by the analysis of antibodies.
Although the presence of antibodies is indicative of the COVID-19 disease, there is currently insufficient evidence to support whether or not their presence confers immunity.
A panel of SARS coronavirus 2 IgG and IgM antibodies (SARS-CoV-2 Ab) can be ordered from SYNLAB to confirm COVID-19 at such a late stage, for subsequent detection of the disease in clinical or epidemiological indications. The combination of IgM and IgG antibodies provides greater sensitivity to individual antibody assays. Your doctor will still be able to tell you for a SARS coronavirus 2 IgG (SARS-CoV-2 IgG) test.
Analyzes can be ordered electronically from the SYNLAB laboratory order list: “Nakkustekitajate diagnostika (Ab, Ag)” >
- “SARS koroonaviirus 2 IgG, IgM paneel” (the code 66708 of the Estonian Health Insurance Fund)
- “SARS koroonaviirus 2 IgG” (the code 66708 of the Estonian Health Insurance Fund)
In the absence of electronic ordering, it is also possible to order the analysis based on a paper referral letter.
The sample material is serum. The analysis can be stored at room temperature for two days, and at 2–8 °C for seven days. The result is received within one working day.
The study referral form for detecting antibodies in venous blood sample (SARS-CoV-2 IgG) can be found HERE (in estonian).
A reminder to doctors on SARS coronavirus 2 IgG (SARS-CoV-2 IgG) can be found on the SYNLAB website (in estonian).
