I have to do this TB Skin test for my college... I did it like 7 years
ago it was positive because as a child i was given BCG. Now I do not
want to do it again.. just want to directly do the chest x-ray. But
School say I need show them the documentation before doing the x-ray.
The problem is that I do not have any documentation.. I was wondering
if I do the TB skin test again.. would it be "serverly" positive ?
Because As I understand .. The infection was "recalled" after the
first test which was 7 years ago. I have no other choice. Any input?

If you received the BCG vaccination then you should have the BCG scar on
your arm to prove it to the doctors. This should be all they need as
proof. You might have to attend the skin test session, but once there
tell the doctor you've previously had the BCG vaccination and show him
your mark.

NO BUDDY you are confusing bcg with smallpox vaccine... BCG do not have scars.

Have you ever received the BCG vaccine? Very few Americans have and so
they are unfamiliar with its results, but here in the UK it is routine
for teenagers to be given it.
I have had the BCG vaccination as have my brother, sister and most
friends. We ALL have the typical vaccination mark of BCG on our arms.
Those of us born before 1970 also generally have had the smallpox
vaccination and have the scar from that too. The two scars look very
different and anyone who knows anything about preventative medicine can
easily distinguish whether a vaccination mark is from smallpox or BCG.

There are many vaccinations that produce scars, but BCG is not one of
them.
Bacille Calmette-Guèrin is the standard vaccine for TB.
If you take the germs and crush them, and extract the juice with
WATER, you get the OLD-STYLE Tuberculin. This is used for the
Tuberculin Tine Test. A tine is a TOOTH, like that of a plastic
hair-comb. It is dipped in the juice and pressed against the flesh
without breaking the skin.
If you have TB ANTIBODIES, either from vaccination or from TB
exposure, your system will be fooled into thinking that the old-style
tuberculin represents a TB attack. The antigens in the contaminated
skin summon the antibodies, and a pimple appears within three days at
each point where a tine had been pressed against the skin.
The trick is used on COWS as well. In some countries, only TT milk is
allowed (TT-tested). That means that the cows were never exposed to
TB. Countries where the milk is not properly tested still have TB
outbreaks. It is present in the milk, and causes both lung TB (spread
also by coughing) and bone TB - and a few rarer variants.
It was pointed out that there are often FALSE POSITIVES.
It is true that there are also FALSE NEGATIVE results. I seem to
remember seeing a Mayo Clinic report quoting false negative in
Addison's disease.
TB has the power to MUTATE, so when it is found, a MIXTURE of
antibiotics is used for treatment to ensure that all mutant forms are
killed. With just a single antibiotic, some antibiotic-resistant forms
might survive.
My researches suggest that the Addison's disease form is a rare mutant
TB that can live in the chemically-hostile environment of the Adrenal
Cortex. Normally, the steroids would kill germs. It is precisely
because the TB has found its niche in one adrenal that it chooses to
invade the other also. Addison's disease requires that over 90% of
adrenal tissue is destroyed - and on BOTH glands.
I call this mutant Bacillus Tuberculosis Addisonii.
The loss of steroids in Addison's disease RAISES the T-cell count -
which SHOULD lead to INCREASED immunity. However, it seems that there
is a "SHIFT TO THE LEFT" in the T-cell spectrum - too many immature
cells. So immunity actually DECLINES. This might explain the false
negative.
When the cells have been washed out with water, they can also be
washed out with ALCOHOL. This liberates the alcohol-soluble protein.
This NEW-STYLE Tuberculin is not used for a tine test.
In passing, I would mention that the researches of Drs. Cutler and
Morton led to a CURE for bladder cancer. Donald L. Morton's treatment
by passing BGC into the empty bladder once a week for six weeks cures
70 to 80 percent of cases.
This is the ONLY immunological treatment for cancer approved by the
American FDA.
I suspect that the cure-rate could be increased to 100% if all those
who were not cured were VACCINATED with BCG, and if after a delay to
let immunity develop the treatment was repeated.

This, you assume, of course. There is no way to prove, even with a
normal chest X-ray, that you also haven't actually been exposed to
tuberculosis and that your PPD is positive only because of the BCG.
This is why we don't use the BCG in the U.S. It doesn't help much with
the spread of tuberculosis, but it sure makes identification of
carriers and decisions on prophylaxis more difficult.
Also, you didn't specify how many millimeters of induration you
actually had to be considered "positive." 5? 10? 15? 20?

Unfortunately, that's not the school's problem.
>I was wondering
>if I do the TB skin test again.. would it be "serverly" positive ?
Probably not. The thing is, though, were you my patient, you wouldn't
be in this quandary. Had you actually had a truly positive TB test
(>10 mm induration, I would guess, without knowing otherwise your
circumstances) with a normal chest X-ray in the first place, I would
have treated you with 9 months of isoniazid and you'd be done with it.
Then for college you'd have documentation of a positive PPD, normal
chest X-ray, and completion of prophylaxis, so you'd be excused from a
repeat PPD.
>Because As I understand .. The infection was "recalled" after the

Just go ahead with the PPD. I would guess that if your "positive" one
from 7 years ago was only from the BCG, it should be even less
"positive" now and you might actually be off the hook. If it's
strongly positive and you end up going on prophylaxis, it might
actually end up saving your life.

You might like to consider QuantiFERON-TB Gold Test.
