Mixing blood from two individuals can lead to blood clumping or agglutination. The clumped red cells can crack and cause toxic reactions. This can have fatal consequences. The differences in human blood are due to the presence or absence of certain protein molecules called antigens and antibodies. The transfusion will work if a person who is going to receive blood has a blood group that doesn't have any antibodies against the donor blood's antigens. But if a person who is going to receive blood has antibodies matching the donor blood's antigens, the red blood cells in the donated blood will clump.
What else can I help you with?
Why is blood type checked before a tranfusion?
Blood types must be matched specifically except of the case of O neg. which I have.
Why must blood be matched before a blood transfustion?
you have a certain blood type, and if you get a bloodtype that doesn't math yours or is able to cooperate with yours you body could reject it and it could make you sick. ~Rae
Why must be matched before a blood transfusion?
red blood cells have protein embedded in their membranes. people make antibodies against these proteins - except the ones they already have. thus, a doners and a recipients blood "type" must match. There's more ... but it'll start you off.
Do blood types have to be matched before blood can be transfused?
Yes, blood must be transfused into a body with the same blood type. If blood is transfused into a body with a differing blood type , the body may become ill and fight to kill the differing DNA.
What risks for a recipient in a blood transfusion are there?
The blood given by transfusion must be matched with the recipient's blood type. Incompatible blood types can cause a serious adverse reaction (transfusion reaction). Blood is introduced slowly by gravity flow directly into the veins
Can a dog get a blood transfusion from cats blood?
This belief is common enough that I've heard it before, but in fact it's generally a very bad idea to attempt to transfuse blood across species. Cats have three blood types (A, B, and AB)... they don't have anything like the human "Universal Donor" O type, so transfusions for cats must be cross-matched.
When do you not take a blood sample?
Samples must be take before milking
Before a blood donation is made the phlebotomist must always check the blood donors?
hemoglobin value
What is matched in an organ transplant?
For all organ transplants (except corneas, which I don't know about), blood group must be compatible and body size must be appropriate. Gender is not matched (the benfit of matching this is marginal, and is outweighed by the additional waiting time required to match this), nor is ethnicity (however some blood groups are more common in some ethnicity's, so it's sort of self-matching). Kidney's require 'tissue matching' along with all of the above.
Which organ must the bloodpass through before it is returned to the rest of the body?
Your blood must pass through your lungs, before it goes to the rest of the body.
Why can a person receive platelets donated by anyone but must receive a particular type of whole blood?
Platelets don't carry any specific anti-body or antigen that would need to be matched up as the whole blood does as to not cause coagulation
Which organ must the blood pass through before its returned to the rest of the body?
Spleen
