Blood Compatibility Made Easy

Blood compatibility may seem like an impossible puzzle to figure out when you first learn.

However, once you learn some of the important properties of blood, it is much easier to determine why certain types of blood are compatible with others. In this post, we’re going to look at blood components, blood typing, blood matching and compatibility.

Why is blood compatibility important?

We determine blood compatibility in order to administer blood transfusions to patients when their blood levels are low.

How does it work?

The process of transfusion of blood to the patient begins by checking the type of blood of the patient through a process called typing. During this process, the blood of the patient is labeled as blood type O, A, B or AB. This process also determines whether the blood type is negative or positive when the Rh factor is present. This blood sample is then cross-matched to the donor to determine compatibility.

What are the 8 blood types ?

A Rh+, A Rh-, B Rh+, B Rh-, AB RH+, AB Rh-, 0 Rh+, or 0 Rh-

What are they made up of?

All 8 blood types are made up of different combinations of certain molecules.  For instance, it’s the antigen molecules in the Red Blood Cells that determine an individual blood type. These two antigens are A and B and are sugars. Red Blood cells also consist of additional antigens which are proteins known as Rh antigens.  There are also molecules floating around in blood plasma called antibodies.

Blood Type A+

Antigens – located on the surface of red blood cells

A antigens

Positive (Rh+): This indicates that Rh antigens are present

Antibodies – located in the plasma

B antibodies

Negative (Rh-): This indicates that Rh antigens are missing

Antibodies – located in the blood plasma

B antibodies
