How do you differentiate between different blood groups?

You must have heard the words of encouragement sometime saying  ' Be positive' or don't " be negative". There you go ! These are two blood groups with one solid difference between them. Bad example? I know.

Your blood type is based on whether or not certain proteins are on your red blood cells. These proteins are called antigens. Your blood type (or blood group) depends on what types your parents passed down to you.

Blood is often grouped according to the ABO blood typing system. The 4 major blood types are:

  1. Type A
  2. Type B
  3. Type AB
  4. Type O

A blood sample is needed. The test to determine your blood group is called ABO typing. Your blood sample is mixed with antibodies against type A and B blood. Then, the sample is checked to see whether or not the blood cells stick together. If blood cells stick together, it means the blood reacted with one of the antibodies.

The second step is called back typing. The liquid part of your blood without cells (serum) is mixed with blood that is known to be type A and type B. People with type A blood have anti-B antibodies. People with type B blood have anti-A antibodies. Type O blood contains both types of antibodies.

The 2 steps above can accurately determine your blood type.

Rh typing uses a method similar to ABO typing. When blood typing is done to see if you have Rh factor on the surface of your red blood cells, the results will be one of these:

1.Rh+ (positive), if you have this cell surface protein

2.Rh- (negative), if you do not have this cell surface protein


I hope this answers your question.
