到底Mantoux Test能不能测出是否接种过BCG呢？

也许俺的Mantoux Test皮试是白做了。中国的医疗纪录就是成问题啊。大家为了报销，用过的姓名就都是一箩筐。追查小时候生病时的处方和接种过的疫苗就更是Mission Impossible了。

至于这个问题，还是那个包治百病的理由——个体差异。

The effect of BCG vaccination on tuberculin reactivity

• The level of reactivity in a vaccinated person is variable, ranging between 0 and 15 mm. Reversion can occur (eg, the reaction wanes with time).
  

• A Mantoux reaction of > 15 mm induration should not be attributed to BCG vaccination.

• There is no relationship between the post-vaccination Mantoux result and protection against TB disease. Routine post-BCG vaccination tuberculin testing serves no purpose
