回複：請問pjiang關於孕婦的體檢

If you read my post, you would know TB+TD is ok. Understanding your concern, may I suggest you to hold exam if you do worry it that much?
According to I-485 Standard Operating Procedure (9/28/2001), applicant may submit I-693 on a later RFE (Page 39 of 269).

"If no medical record has been submitted, note on the processing worksheet so that a RFE can be mailed to the applicant prior to adjudication.
NOTE: NIW Physicians are not required to submit an I-693 when filing an I-485. Applicants will be notified when the I-693 is to be submitted by a RFE from INS after officer review."
