Blood Type and Rh Factor
The Blood Typing and RH Factor Test determines your blood type [either A, B, AB, and O] and Rh factor [negative or positive]. Did you know there are several benefits in knowing both?
Blood type is determined by the types of antigens (or markers) on your blood cells. Antigens are proteins on the surface of your blood cells that can cause a response from the immune system – which is good in fighting disease.
The Rh factor is a type of protein on the surface of red blood cells. Red blood cells that contain protein are called Rh‐positive and the red blood cells that don’t are Rh‐negative. If you have Rh‐negative blood, it can be given to anyone because it can’t be identified as foreign in other people’s bodies (because it doesn’t have an antigen.)
