Is a marriage between two people with same blood group risky?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

My boyfriend and I have the same blood group, which is B positive. I am concerned about whether the same blood group will affect our child in the future. Will the child suffer from thalassemia? Can a newborn develop any abnormalities if the parents have a similar blood group?

Kindly help.

Hello,

Welcome to icliniq.com.

Thank you for your query.

People with the same blood group can marry and have children without any complications. So do not worry as far as the same blood group is concerned. However, genetic counseling can be done to rule out thalassemia before planning your wedding if you are a relative.

So I suggest you check for the Hb (hemoglobin) electrophoresis test by the HPLC (high-performance liquid chromatography) method to rule out thalassemia minor.

I hope this has helped you. Thank you.
