Why to perform antibodies test after vaccination?

Antibodies are a protection mechanism facing infections. However, its generation after vaccination is not the same for everybody. Serological tests enable to detect specific antibodies presence in our body. To perform a test after SARS-CoV-2 coronavirus vaccination is very useful to know our body response.

This test detects if our body has now these antibodies and if we are immune.

When can I perform the test?

Experts recommend test performance three weeks after vaccination is completed. You can perform it before that because there are no contraindications, but you will have an optimal result after the third week.

Which sensitivity and specificity do tests have?

Tests are very reliable:

  • Sensitivity 96,41%.
  • Specificity 99,90%.

The technique is correlated with WHO 20/136 international standard. Cut-off point is 21,8 BAU/mL (BAU: Binding Antibody Units).

How does it work post – vaccination test?

Post- vaccination serological tests are performed by blood sample obtained through vein puncture (a conventional blood collection). The sample is analysed and the result will be in a numeric value over IgG antibodies quantity facing S1 protein of SARS-CoV-2 coronavirus in our body.

What are IgG antibodies?

IgG antibodies are produced later, they are a marker of the late stage of the disease or when it is overcome. When this happens, IgG antibodies remain on the blood, so they can protect people against a possible future infection.

Do I have immunity against COVID-19?

There is correlation between antibodies presence and protection level against the disease. However, for now there are no conclusive studies about neutralizing IgG antbodies level fo SARS-Cov-2 or about the time it remain in our body.
