Those who have to go through with the meds -- Now a days photographers usually don't use the negatives for colored snaps , as they are clicked using a memory card or pen drives , and moreover at the time of Xray you would be asked to sit in front of a small webcam type of camera just to assure that a right person is being checked. 5 photos each for all your family members are required definitely (Accompanying & Non-accompanying), so don't forget them ...Good Luck for your Medicals !
