About Blood Types
You may not know it, but different people have different types of blood running through their veins. Blood is classified based on the presence of specific antigens on the outside surface of red blood cells (RBCs). There are A-type and B-type antigens, and an individual may have either one, both, or neither present. Another antigen, called the Rh antigen, may also either be present or absent from RBCs.
Blood types are defined through a combination of the ABO and Rh categorizations. People may be A, B, AB, O and this classification may be either positive or negative. Blood types cannot be mixed within one’s body. If a different blood type is introduced to an individual, the body will begin to form antibodies to fight off this foreign substance.
Blood Transfusion Reactions
When blood transfusions are performed, it is extremely important for physicians to ensure that the correct blood type is injected into the patient. Failure to do so may cause the patient to experience an adverse reaction. Symptoms of blood transfusion reactions include the following:
- Chills and fever
- Rashes
- Bloody urine
- Dizziness and fainting
- Flank and back pain
If a blood transfusion error is made, then the patient will need immediate treatment. In milder cases, the patient is given pain and fever relievers, immune system treatment, and fluids. In severe cases, the situation may be fatal.
