Hello. Very Good evening. For every minor or major elective surgery, doesn't matter which region,  its the right of the surgeon to Rule out three infections as follows : 1. HIV 1 & 2 2. Hbsag ( for Hepatitis B) 3. Anti HCV Antibodies ( for Hepatitis C). Without these reports, no surgeon will perform surgery not only in india, I Whole world. Its a standard procedure.  You have to sign the documents before surgery. Regards.
