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?

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.
