Any false positive TB blood test results out there?
Infectious Diseases | Last Active: Jun 21, 2023 | Replies (14)Comment receiving replies
Can I have a false positive tb test (subcutaneus tuberculin) related to getting a Monkeypox vaccine (Jynneos)? I was vaccinated two days ago, must I wait a period of time to get the tb skin test, or there is no direct interference with the monkeypox vaccine in relation to false positive or negative results?

Thank you very much.

These two infectious agents are completely different - TB is a mycobacteria, monkeypox is a virus. Based on that alone, there should be no risk of a false positive after the vaccination. If by chance you should get a positive result from the TB Mantoux test, this can be confirmed or refuted by the more accurate Quantiferon TB Gold test, which requires a vial of blood be drawn.
If you have more questions, you could ask your health provider.
