how to change blood group in driving licence

To change or update the blood group on your driving licence, you must provide officially verified documentation to the licensing authority. The process usually involves:

• Obtaining a verified blood group report from a licensed medical or blood center.
• Submitting this verified report along with the required application and medical certificate to the Regional Transport Office (RTO).
• The authority will update or correct the information in their records, typically coinciding with a new license application or renewal.
