Any person above the age of 18 years can legally donate his part of liver. However, in India as per Human Organ Act 1996, liver donation is restricted to family members (brother, sister, father, mother, son, daughter) or close relatives (under, aunt, cousin, brother-in-law, sister-in-law, grand parents). Medically, the liver donor should have a compatible blood group (same blood group as patient or O group), should not be more than 55 years of age and should be medically fit and psychologically sound. All voluntary liver donors are evaluated thoroughly to look for medical and surgical fitness.
