Asked for female, 39years old from Bangalore
Dear user, having o+ blood group is not harmful. There is no test required for this. Everyone has a different blood group and the grouping is necessary for various factors like blood transfusions etc. No health tests are required, but your annual check up is required. Good luck.

Thank you.
