assays in the employee clinic and I was negative. I think this is available
now. |

来不幸得了TB
如果按照这个protocol,岂不90％中国人都要吃异烟肼。

是的。如果在医院工作，解释很麻烦。

发帖数: 312 | 9 just find something in uptodate, it is explained well
BCG vaccination — BCG vaccination is a well known but frequently
misunderstood cause of false positive tuberculin reactions. The effect of
BCG on TST depends primarily on the age when vaccinated . BCG vaccination in
the first year of life causes no discernable effect on TST after 10 years
or more. Vaccination after the first year of life (such as at entrance to
primary school at the age 5 to 6) causes a stronger and longer lasting
effect. As many as 20 percent of individuals remain positive 10 years or
more after vaccination at this age. In pediatric populations, the interval
since vaccination is important since there is progressive waning over the
first 10 years after vaccination.
Since many foreign-born persons do not know their BCG vaccination status
or age at vaccination, current and past BCG vaccination policies for most
countries of the world may be reviewed online at the World Atlas of BCG
Policies and Practices .
TST reactivity caused by BCG sensitization can be distinguished from
latent TB infection by interferon-gamma release assays. (See "Interferon-
gamma release assays for latent tuberculosis infection".) |

国人传染， 因为少部分外国人卡介苗失效并且得了latent TB。
只可怜我们正常人种过卡介苗的要吃这么久毒性这么大的异烟肼， 完全就是种歧视。

发帖数: 1373 | 11 I remember a question on step 3. A healthcare worker who is ppd+ with
negative X-ray refuses to take INH. the answer is he/she has the right to
refuse. it won't affect his job. he just needs to follow up regularly.
I think different hospital has different policies. However, how can they
check if you are actually taking the medication or not? |
