What are the different blood types, and how does having a positive blood type impact blood donation and transfusion compatibility?

There are four main blood types: A, B, AB, and O. Each blood type can be either positive or negative, based on the presence of a protein called Rh factor. Having a positive blood type means that the Rh factor protein is present in the blood. When it comes to blood donation and transfusion compatibility, individuals with positive blood types can receive blood from donors with either positive or negative blood types. However, individuals with negative blood types can only receive blood from donors with negative blood types. This is because receiving blood with a different Rh factor can lead to a negative immune response in the recipient's body.
