Question: Can someone's blood group change?

My birth certificate shows blood group as O+, while a test done 4 years ago gave AB+. A test done yesterday gave result as B+. Is this possible? Should I do more tests?

My mother is O+ and father is AB+.

Brief Answer:
Can not change.

Detailed Answer:
Hi,

Thanks for the query.

Blood group of a person can not change as it is genetically determined. You have mentioned that your birth certificate shows as "O" positive and tests done 4 yrs and yesterday showed different results.

This is not possible. There is some technical error. So, please get your blood group done from a reliable lab nearby your area to confirm your blood group.

Hope this answers your query. If any further clarifications, will be happy to help.

Regards.
