Hi. It is likely that the shadow on your chest x-ray is just the residual scar, in that case, u will have no problem in getting a FIT TO WORK certificate. However, when you go to a pulmonologist
, he will probably ask for further investigations to rule out active infection- for example, 3 consecutive days morning sputum
specimen for AFB staining, he may also ask for a CT chest as that shows the active and old lesions more clearly than the Chest X-ray. My advice is to definitely consult him not only to get your certificate but more importantly to rule out active infection.
