[|Human|] my FATHERs montux test and serum test is negative but on the basis of x-ray doctor has advised two forecox tab daily befort breakfast. My question is just on the basis of x-ray can we detect tb when other tests are negative. my father age is 69 and he is feeling very week after taking forceox. please guide
[|AI|]  Based on clinical findings and after corroborating with the X-ray findings, if the doctor finds evidence of tuberculosis, it can be treated as tuberculosis even if Manitou test and sputum test are negative. At advanced age like that of your father, the immunity automatically comes down and susceptibility to tuberculosis increases. However, for confirmation, TB Gold Quantifier test is considered as gold standard for diagnosis, and you may opt for that if you have a confusion. Please note that it is a costly investigation.
