I ask you if B- Can you donate blood to B +

1 Answer:

Hello Ali,


Thank you for asking HealthReplies.com.

Blood type can be done by several methods, including for example the ABO and rhesus blood group methods. This classification of blood is important, especially in some cases, for example for the purpose of blood transfusion.


People with blood type B- means having B antigens on their red blood cells, and producing anti-A antibodies and anti-rhesus antibodies on their plasma. Meanwhile, people with blood group B + means they have B antigen and rhesus antigen on their red blood cells, and produce anti A antibodies on their plasma.


People with blood type B- can donate blood to people with blood type B +. But on the contrary, people with blood type B + can not donate blood to people with blood type B-, because it can trigger hemolysis which can be dangerous for blood recipients.


However, blood donation is not merely done by considering the blood type only. There are many other aspects of donors that are also worth considering, including age, blood pressure, hemoglobin levels, history of illness, and so on. Therefore, you should consult with your doctor directly regarding this matter.


Hope this helps ...
