What is Blood type A-H?

Question

I want to know the difference of this kind to the other ABO group. What are the possibility of knowing if this kind has been around for quite sometime but was discovered only this time.

Answer 1

**There is no blood type generally recognized as A-H.
** HIV-1 has a designated A-H subtypes based on genetic differences. This is the most common subtype of HIV-1 in Africa. HIV-1 subtypes are designated A through H, M, and O.

I believe what your question pertains to this HIV-1 subtypes A-H which is detectable during blood screening for HIV-1. This has nothing to do with the ABO Group.♥

Answer 2

Blood Type A-h
