A blood type is a classification of blood based on antigenic substances found on the surface of red blood cells. Depending on your blood group, many different antigens may be present on your cells. Your blood type is determined by a combination from both of your parent’s blood types. One of the main reasons for having blood types is to prevent problems during blood transfusions. If the transfusion goes wrong the side effects can be kidney failure, shock, and in extreme cases death. However, there are tests that can be performed to prevent a reaction from occurring. Cross-matching blood is an example of one of these tests. Cross-matching blood is a way of telling whether your blood is compatible with your donor’s blood. A technician will mix the blood types to check if they form clumps. If no clumps are visible, the donor’s blood will be acceptable.
There are eight common blood types. They are as follows, O-,O+,A-,A+,B-,B+,AB-,AB+. The blood type AB- is the rarest group, 1:167 have this type. O+ is the most common blood type with 38% of people having it. People with the blood type O are known as universal donors and in emergencies can donate to anyone. Also, individuals with the blood type AB can receive RBC’s from any blood type. These individuals are often known as universal recipients.
1. Do you think that someday it will be possible to complete a blood transfusion with any blood type without suffering from a reaction?
2. Why is it that individuals with the antigen system hh can only receive blood safely from other hh donors?
3. Is it possible for a person's blood type to change throughout their life? If so explain how.

1.Yes i think it will be possible to complete a blood transfusion with any blood type without suffering from a reaction, because of the tests that can be performed to prevent a reaction from occurring, like cross-matching.
ReplyDelete2.people with this blood type can receive blood only from other donors who are also hh because a transfusion of "normal" group O blood can trigger a severe transfusion reaction.
3. Almost always, an individual has the same blood group for life, but very rarely an individual's blood type changes through addition or suppression of an antigen in infection, malignancy, or autoimmune disease.
1) i belive that one day it will be possible to complete a blood transfsion bewtween two different blood types. there is a type of test that can be performed that will prevent a raction such a cross matching.
ReplyDelete2)if you do not receive blood from another hh donor there will be a severe reaction your body would not accept the blood.
3)in very rare cases it is possible for the persons blood type to change. it would be changed from autoimmune disease.
1. I have no doubt it will be possible someday because science is so astounding.
ReplyDelete2. As with most blood types, one can only recieve blood from a donor of the same blood type.
3. Although you didn't say anything about it in your information, it may happen after a organ transplant, but it's very rare.
1. I believe it is possible if they come out with a drug to go with it. that will give it the appearance of your blood type to your cells.
ReplyDelete2. this would cause a negative, possible fatal reaction if the same blood types are not used.
3.It is possible if you get a bone marrow transplant.
