• They are determined by the protein (antigen) found on the RBCs.

•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.

•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
•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.

•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

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

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

• 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.

•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.
