LD以前做TB test，20mm，反应比较厉害，医生还注明“advised to not have future
PPD skin tests"。 再做估计胳膊就变大力水手了。所以这次他就直接X-ray了，没有
做TB。
照一些人的说法，没做TB要被RFE。
不过USCIS网站上有这么一段：
Q. Are there any exceptions to the initial TB testing requirement?
A. Yes. Under the May 2008 TB Component of the Technical Instructions for
the Medical Examination of Aliens in the United States, and its update, an
applicant may not be required to undergo the initial TB screening testing
with a TST or IGRA under the following circumstances:
(其中一项，就是我LD的情况)：
Applicants who have a history of a severe reaction with blistering to a
prior TST.
所以我们医生就选 "Not administered (TST exception applies; please explain in
Remarks section below)”
然后在X-ray哪里选 “Chest X-ray required due to TST or IGRA exception (...)"
然后 Remark: Patient had positive severe PPD reaction on xx/xx/xx.
这样是不是就行了，谁这么干过，能说下结果吗，有没有被RFE？
谢谢！
