- Is ABO blood compatibility
enough for the safety of blood
transfusion?
Besides ABO blcompatibility concerning the Rh bloodood compatibility the (^)
system must also baddition it is of fundamental importancee checked. In (^)

- What is the Rh factor?
RH factor is a protein ocell plasma membrane that behaves asf the red blood (^)
antigen a humoral (antiboin blood transfdy-baseusions triggeringd) immune
response. Most people present the
protein part of the Rh+ group. People that doin their red blood cells and are
not have the protein classify as Rh-.
The origin of the name Rh factor is

rhesus monkeys (“Macaca mulatta”).
- How are the antibodies
against the Rh factor formed?
Anti-Rh antibodies are made by humoral
immune response. When an Rh-individual makes contact with the Rh (^)
factor this is recognized as foreign
(antigen), the primary response begins and smallimmun amounts ofe (^)
anti-Rh antibodies and memory B
