在给妈妈办绿卡。妈妈在国内体检没什么问题，这儿移民医生却发现tb test阳性，x光阳性, 最后体检表上标得是latent TB infection。

请教万能的华人姐妹：
1. 这种情况会影响绿卡申请吗？
2. 移民医生就简单说要吃6个月药，让我们自己去找卫生部门 (county health system)。妈妈才来不久还没买insurance. 不知道这治疗严重不？我们现在买保险还来的及吗？

谢谢大家啦！
---------------------------------
update一下， 妈妈没有咳嗽，以前也没有得过肺结核（从记事开始）。移民医生说是陈年的，不active， 应该没有传染性. 也sign了体检report。

不会影响任何事情。很多亚洲人都有TB感染，吃药就行了

这在中国是免费治疗的，美国也是吧？

抗结核药的副作用很大的，吃药期间并不舒服，钱应该不是什么问题，政府的卫生部门收费不会多。建议再查一遍，做一次血检，确定是不是有过结核感染。皮试阳性几乎所有的中国人都有，我们种过卡介苗。X光阳性不好办，不知道有没有假阳性一说，所以还是去做个血检吧。抗结核药能不吃还是不吃的好。如果没问题，让这个医生再出一份报告，或者换个移民医生就是了。这材料是移民医生封好，自己和其它材料一起递上去的，所以先缓一缓吧。

血液检查看有没有感染是最准的

X ray阳性的话，血检基本一定是阳性了。我父母没做皮试，直接血检的，血检阳性X ray阴性

PPD, is the skin test for screening, when it is negative, meaning mostly negative for infection. myth: BCG aka 卡介苗 can show PPD+, not really. This thing is not working as a vaccine, nor it will cause false positive in most people. Though most Chinese had it done, it is basically a joke. So Chinese people could have PPD negative even if they had BCG, indicating such population never had TB positive infections. In fact, a lot of Chinese don't have TB. So if anyone says Chinese people =PPD+ or any nonsense about most Chinese has TB, that person is a fxxxing racist. Sorry about the language. So, when it is positive, patients need QuantiFeron gold or CXR.he quantiferon gold is the blood test, rather new test comparing to CXR. There is another blood test, T-spot, similar thing. If the blood test is new, it means that the patient has the infection, then she/he will need further test if it is latent TB infection or TB disease. If negative, then infection unlikely. Notice, unlikely, none of the tests is 100% in medicine, bummer. Then the CXR, if it is positive then it is positive. So for latent and active TB, it would be quite obvious for active TB, lots of other symptoms, fatigue, fever, cough, shadows on CXR, sputum, positive sputum culture...... Then treatment: still the same old drugs like decades ago, isoniazid, rifampin, ethambutol, pyrazinamide. For latent TB, we usually use Isoniazid(INH) or rifampin. Be sure to take B6 when using Isoniazid to avoid Side effects. Rifampin may cause red urine or tears, interesting. Both drugs are well tolerated by themselves, only might have drug-drug interactions when taking other meds at the same time. Make sure your doc knows about that. Otherwise, definitely don't miss the follow-up appointment. For CXR radiation, honestly, I feel people are so overacted to it, as for adults, extra 1-2 films really are nothing. People get 2 CXR equivalent radiation from the person sleeping next to them each year. I always joke about it: everyone should have a CT in the ER, it would reduce the cost tremendously in total and increase the efficiency.
