I am just updating this information on visa journey so that people who come in to similar situation can get some help from this experience in India. But process may change in future.
Don't be disheartened if doctor refers you for further Sputum tests. These days doctor will refer even for smallest of scars on lungs. Please don't try to jump to other medical locations for another medical because this will go against you. Most certainly you won't have TB as it is a dangerous disease and you would have already known if you have one by now. Also even if you had one in past they are just looking if its still active or not. Or worst case probably there is 6 months process to cure TB if it comes positive.
If you fail Xray test as per process in 2018 you won't be able to attend interview. If you already have an interview date and the date lies within 2 months then you would need to email embassy for further process. Then you will be asked not to come to interview .
Once sputum test arrives in 2 months the hospital will send results directly to Embassy. Then you will get email from embassy that your medical has been received and a new interview date will be given.
Disclaimer: The process mentioned may be incorrect or changed. It's just information gathered from one of the such experience.
