How can you tell the difference between blood types?:confused:

Type A has A antigens and anti-B antibodies, type B has B antigens and anti-A antibodies, type AB has A and B antigens (A and B are co-dominant alleles) and no antibodies. Type O has no antigens but both anti-A and anti-B antibodies. That's why type O is called the universal donor and type AB is called the universal receiver. Anyone can have type O blood for a transfusion but type O people can only accept type O because if they receive anything else the antibodies attack and the blood agglutinates (or clumps). And type AB can accept anything because it has no antibodies to attack anything. Anything else you need to know?

By doing specific testing on the blood (the plasma and the red cells) with specific antigens and looking for macroscopic (the naked eye) and microscopic (under the microsope) agglutination. But to the normal person there is no way to tell a blood type. Also if you have regular lab tests at the doctor (like your cholesterol), he can't tell you your blood type just from that. This test is done in Blood Bank in the Lab usually at a hospital.

Look up the difference between the blood types and why is dangerous to give the wrong blood type to an individual.
