HI Thank for asking to HCM I really appreciate your concern, to rule out possibility of tubercular infection there are number of method or test can be done but important is clinical sing and symptoms if there is no concrete sing of tubercular infection and test are doubtful then the advantage of this goes to clinical sign and in this situation better not to initiate the anti TB drug clinical sign and symptom still remain the ideal way of diagnosis to the extent that some time on the basis of clinical evidence treatment can be started and if this improves the clinical condition then treatment of AKT continued, hope this information helps you, take care and have a nice day.
