My Mother and Father had their Medical Examination on Monday 21st October. My Father had his Chest X-ray done, but the Medical Officer ordered him to undergo few test and said that he needs to reschedule the appointment date which is December 3rd 2024 in Mumbai. I don't know what the probable cause for the tests he was asked to undergo for, do I need to reschedule the original appointment date or is it ok to go for the interview.
