Not sure where anyone would be giving advice on this as it is utter nonsense. My now husband, on his K1 visa exam tested positive for TB, was then given a six month treatment and because he could not do it in Jakarta at the assigned US Embassy Hospital, he had to wait ONE year after the six month treatment was finished to go back and do the medical again. Then when he went back to do the medical, because now he had scarring from the TB, they did the sputum test and had to wait 3 months before the results and had the medical results sent to the US Embassy. To make a long story short, two years later, while in the process of the CR1 visa, once again went to the medical and once again subjected to the sputum test and another 3 month delay for the results. It's one of those things, if you had it, you will get the sputum test and there is no getting around that. Good luck.
