I want to ask. When I was in junior high school in grade 2, I had a blood test at school and the result was my blood type is B. But now after 8 years it has become a B + yeah, would you explain? Thank you

1 Answer:

Good evening, thanks for asking at HealthReplies.com. A person's blood type will never change for any reason and no matter what. Even if someone has done a blood test and blood type A, then has another blood test and then the blood group becomes O or something else, it is most likely because of the contamination of the blood sample, naming errors, carelessness, or other errors. Because it is indeed impossible for someone's blood type to change.


But in your case, the condition is not the case. The results of the blood type examination in the form of B + that you are doing now do not conflict with the results of your blood type examination in the past, the difference is only now that the examination is more detailed.


Simply put, a person's blood identity is twofold, blood type and rhesus. Blood type is, as you already know, consisting of A, B, O and AB, while rhesus is only divided into two, namely positive rhesus (+) and negative rhesus (-). In essence, each person has both information, not just one. So in total there are 8 variations of a person's blood type identity, namely A + and A-, B + and B-, O + and O-, and AB + and AB-. As for your case in the past, it was only called blood type B, because that time the rhesus was not checked. Even if checked, the results will definitely be B + as well. So there is nothing you need to worry about, because there are no abnormalities that you experience. If you are still in doubt, you may create new questions or ask directly to the nearest general practitioner. So, hopefully answering your question.
