Antibodies

What’s an antibody test?

An antibody test detects the presence of antibodies against Covid-19, that suggests a recent or past infection.

There are two types of antibodies; IgM and IgG.

IgM are the antibodies that are produced as a response to an acute infection. IgG is found later in the process and after the infection has passed. IgM is found within a week after infection, while it takes approximately 10-14 days for IgG to be detected.

How accurate is the test?

Covid-19 antibody tests are supposed to be both sensitive and specific. The measurement of how sensitive and how specific a test is, is called Sensitivity and Specificity, respectively..

  • Sensitivity = The propability that the test result is positive if one has antibodies.
  • Specificity = The probability that the test result is negative if one does not have antibodies.

Our antibody tests has a sensitivity of 90% and a specificity of 98.5%, which means that they meet the requirements of The Public Health Agency of Sweden.

How does the PCR-test work?

First you perform a capillary blod sample, which is done by pricking a finger with a gentle, automatic needle. A small amount of blood is then collected and used together with a buffer in the testing equipment to perform the test. The whole process takes approximately 10 minutes.

After the test you will receive a medical certificate and a copy sent by e-mail, signed and verified by a licensed physician.
