2. There are four different types of blood A, B, AB, O. They are determined by the protein (antigen) found on the RBCs. Prepared by Abeer Alhabash

6. Approximately 45% of the population is group O. No A or B antigens present, think of as “o” antigens present. These individuals form potent anti-A and anti-B antibodies which circulate in the blood plasma at all times. Approximately 45% of the population is group O. No A or B antigens present, think of as “o” antigens present. These individuals form potent anti-A and anti-B antibodies which circulate in the blood plasma at all times. Prepared by Abeer Alhabash

7. Approximately 40% of the population is group A. No B antigens present. These individuals form potent anti-B antibodies which circulate in the blood plasma at all times. If you belong to the blood group A, you have A antigens on the surface of your red blood cells and B antibodies in your blood plasma Approximately 40% of the population is group A. No B antigens present. These individuals form potent anti-B antibodies which circulate in the blood plasma at all times. If you belong to the blood group A, you have A antigens on the surface of your red blood cells and B antibodies in your blood plasma Prepared by Abeer Alhabash

8. Approximately 11% of the population is group B. No A antigens present. These individuals form potent anti-A antibodies which circulate in the blood plasma at all times. If you belong to the blood group B, you have B antigens on the surface of your red blood cells and A antibodies in your blood plasma. Approximately 11% of the population is group B. No A antigens present. These individuals form potent anti-A antibodies which circulate in the blood plasma at all times. If you belong to the blood group B, you have B antigens on the surface of your red blood cells and A antibodies in your blood plasma. Prepared by Abeer Alhabash

9. Approximately 4% of the population is group AB. Both A and B antigens present. These individuals possess no ABO antibodies. If you belong to the blood group AB, you have both A and B antigens on the surface of your red blood cells and no A or B antibodies at all in your blood plasma Approximately 4% of the population is group AB. Both A and B antigens present. These individuals possess no ABO antibodies. If you belong to the blood group AB, you have both A and B antigens on the surface of your red blood cells and no A or B antibodies at all in your blood plasma Prepared by Abeer Alhabash

10. First found in a monkey. Based on whether it has a antigen (protein) D, Rh+ has the protein, Rh- does not have the protein. Prepared by Abeer Alhabash

11. Father--Rh+ blood. Mother is Rh–. Child could be Rh +. 1 st pregnancy--if the baby is rh +, then there are no complications. However, the mother will start to develop antibodies against the Rh factor Prepared by Abeer Alhabash

12. Second pregnancy, if the child is +, the mother’s antibodies can cross the placenta and start to attack the fetus’ blood cells, causing hemolysis. Hemolysis--breakdown of RBC and the release of hemoglobin into the plasma which can damage organs. This is called erythroblastosis fetalis,can cause severe anemia, jaundice possibly death.

15. For each well Place 1-2 drops of blood from one bottle in all 3 wells. 1-3 drops of anti-A serum to one well and stir. 1-3 drops of anti-B serum to one well and stir. 1-3 drops of anti-Rh serum to one well and stir. Look for clumping reaction. Prepared by Abeer Alhabash
