I had the same thing happen to me for nursing school. I guess all medical professionals get the TB test, doctors, nurses ect. I think once a year.
Once they get a positive sign, a big red bump, then they don't have to get the test any more since they will always show up positive after that.
States do have exemptions, but they are for vaccines. The TB test really should
be considered a vaccine since it has the same effect on the
body, but it isn't technically considered a vaccine since its a "test". Although the test if given enough to a person over the years, will develop
a reaction to the test.
This is more of a vibe I've gotten, but a healthy body shouldn't be able to be infected with TB. You see it as the immune system weakens, like in
the old and those with AIDS. With you being on those drugs, they'd be negligent to let you work with old people without being tested. Even without
susceptibility, they have to test you for legal reasons.
If you'd like the biology experiment to occur outside your body, which would be nice wouldn't it, the QuantiFERON TB Gold is a test where they draw
blood and do the tests on the blood, so it won't have any impact on your body. It isn't given every where and your health insurance probably won't
pay for it. Now that I think about it, sometimes you can get an xray and have that count. It doesn't always seem to count, for a healthcare
certification course an xray worked for me, but for nursing they wouldn't allow it.
I am wondering if the Tuberculin is really another word of weakened form of the Virus, which is most vaccinations. I cant get any clear
answers from what Ive found online regarding the safety of Tuberculin.
TB is a slow reproducing bacteria. Tuberculin is just the protein that extends off the surface of the bacteria. When the immune system recognizes
that protein, it'll attack. The protein given in the test is purified so it doesn't contain any sort of infectious potential. If you have TB, your
body will be fighting off the bacteria and it will recognize the protein in the shot and react right away giving off a red spot. As for safety, like
I mentioned all health professionals get it yearly from what I read. The only "unsafe" thing are maybe some of the things in the shot, like phenol
I think was one chemical which can irritate the skin, but the concentration is quite low so that shouldn't be a problem.
If you are worried about the test, I believe you can get a chest x-ray that will detect tuberculosis. But that's gonna cost ya.
The TB skin test takes a good amount of time, sometimes you need to do 2 separate tests. After getting the shot, you need to go back in 2-3 days I
think to have it "read". Do this twice and you're looking at a week. So if you have short notice, they can sometimes be nice and do an xray,
that's what they did for me at least.
The tine test is old as far as I remember. They don't do that anymore and go straight to the mantoux test.
