Hi All,
I hope someone can help me with some clarification. I was reading about the presence of H antigens in different ABO blood group patients, but I am getting different answers depending on what I read. Transfusion Medicine and Hemostasis- Clinical and Laboratory Aspects- 2nd Edition mentions O > A2 > B > A2B > A1 > A1B with O having the most, whereas BBTS Introduction to Transfusion Practice-6th edition mentions O > A2 > A2B > B > A1 > A1B. Maybe it doesn't really have a big impact to my routine work, but it is still good to be in the know. Any thoughts would be welcome.
Regards,
Jermin
