My daughter who is 6 years old diagnosed to have a TB way back July 2008 thru Tuberculin test. She already done her 6 months medication this January 31, 2009. She got another xray but so sad that the TB still there so the doctor adviced me to let her take another 3 months medication. My concerned right now is, can she have another Tuberculin Test again to make it sure she still have it? The doctor is basing on her chest xray of telling me that she still have it. Thank you..
