3. One thing blood tests measure is the Rh factor , a substance found in the red blood cells of most people .

4. Rh factor: This blood type is defined by the amount of integral protein in the Agglutinogenic membrane of the red blood cells

5. Among the NAE [non Abductee-experiencer] Group, 83% had a positive Rh factor and 17% were negative indicating that both groups had elevated Rh negative blood types

6. But besides the ABO types and the Rh factor for which blood is routinely cross-matched, there may be 400 or so other differences for which it is not.

7. In addition to the A and B antigens, there is a protein called the Rh factor, which can be either present (+) or absent (–), creating the 8 most common Blood types (A+, A-, B+, B-, O+, O-, AB+, AB-).
