A member asked:

If you have type b blood and have rh factors, is your blood b- or b+?

A doctor has provided 1 answer
Dr. Gurmukh Singh answered

Incomplete info: If you have Rh factor D, you would be B positive. There are multiple Rh factor antigens, but for + or minus designation, it is only the D factor that counts.
