Hello, I got a job at a school in Canada and I just had my visit medical, they asked me to do a sputum test and wait for the results in 8 weeks. To be on the safe side, I went to see another private specialist to find out if I was at risk with TB and not at all. So my questions are could the doctor offer me a faster TB test? And will my sponsor wait for me because I start work in mid-August? Is this kind of test common? Thank you
