This COVID-19 T-cell blood test can help you and your doctor monitor the overall response of the COVID-19 vaccine to ensure a good immune response.

Test results are helpful when determining:

  • If your SARS-CoV-2 T-cells are activated.
  • If you may need another vaccine dose.
  • If you are protected from others.
  • If others are protected from you.
  • If you have natural immunity from previous exposure.

SARS-CoV-2 IgXSpot T-cell Test

For most coronaviruses, antibodies, which help target the virus directly, can, in some, be short-lived. T-cells are another part of our immune system that targets the infected cells, keeping viruses from reproduction gan can provide long-term immunity even if antibody levels are low.

Why are Coronavirus Antibodies Important?

Antibodies are produced when we are exposed to foreign invaders like the COVID-19. Not only do they help fight the virus, but they also help your immune system develop protective immunity so that your body is better prepared if you get exposed again.
