Re: Can my health center employer require the annual PPD test?
Most healthcare that I know, once you are registered as POSITIVE for the skin test that all that is necessary is a NEGATIVE chest X Ray. I agree with the statements above that if you continue to try and do the skin tests, that each reaction may be worse than the previous. When I had mine, I was told NEVER to do another skin test, however, there is a blood test that can tell you for sure if you do or do not have TB.
My mother tested postive for the skin test due but negative to the blood test. They said it had probably become contaminated or irritated.
Talk to your employer but if they are in the health care then I am not sure why they would demand a skin test again if you have already tested positive. Usually they simply need a negative X ray and you are showing no s/s of active TB.
