Why medical professionals establish the blood type of the donor and the receiver formerly blood transfusions?
Answer:
Blood types must either game or be compatible or it can kill the receiver. In my hospital, not only does the blood sandbank type and cross match the blood, 2 RN's enjoy to verify all the information beforehand the transfusion is started. By the way O cynical is the universal donor - not O positive. Negative and positive refer to the rh factor which, if it is present, make it positive. You cannot give an rh positive to an rh gloomy because you are introducing a new substance into their body. You can tender an rh negative to an rh positive because you are not introducing a different substance.
To prevent mismatched blood types.
Because it has to be completable blood type or a body will reject it and the operation will be pointless..... human body is a especially complex thing, cant a short time ago stick anything in it and hope it will work...
if you mix 2 blood types that do not game the person receving the blood of organ can die it can be deadly like you cant mix a next to b and o is a universal doner
If you mix blood types, your body will reject and attack adjectives your blood. This is because the new blood will mix next to your own blood. With organs it is possible to take drugs so your body won't attack itself. But, beside the blood, since it travels throughout your whole body and go into all your organs, it isn't believable to be able to control it using drugs.
So they can own a match
Here's the Red blood cell compatibility table:
Universal Donor is O- (Can donate to anyone)
Universal Recipient is AB + (Can take anyone's blood)
But besides these two the matching is more complicated.
Recipient
blood
type Donor red blood cell must be:
AB+ O- O+ A- A+ B- B+ AB- AB+
AB- O- A- B- AB-
A+ O- O+ A- A+
A- O- A-
B+ O- O+ B- B+
B- O- B-
O+ O- O+
O- O-
Hope this answered your question :-)
If your blood is Rh denial, it means your blood own not the 'factor' Rh. So your immune system doesn't know the Rh and will not accept a blood next to this (new) factor. This is somehow similar to a bee bite. The new proteins of the toxin stimulates a reaction of antibodies. The response can be so violent for a second or third bee bite that produce unconscious. The same occurs next to the factors A and B.
If your blood is AB Rh+, it vehicle that your immune system knows (it is used to...) the three factor and wont react to a current (donated) blood.
If your blood is O Rh-, it means your blood is free of factor, and you can donate for anybody, but you only can receive blood from another O Rh-
You don't want to see your tolerant dancing Shakira after the transfusion right?! This is to prevent rejection of the transfused blood...
Blood groups correspond to the type of antigens or surface marker on the cells. The prime groups are O A B and AB. Another important float is Rhesus. A person can be Rhesus +ve or Rh-ve depending on whether they hold that antigen on their cells.A creature with blood group O-ve have none of these markers on the cell and can be referred to as a universal donor because most inhabitants could receive a transfusion with their blood and not own a reaction. The point people own a 'transfusion reaction' is because we all produce antibodies against the cell marker that we do not possess. For example, a patient beside blood group A will have antibodies against blood group B. If they received this blood near would be a strong reaction to the transfused blood and the blood cell would be destroyed by the antibodies. Severe reactions can be deadly. In addition, the transfused blood will contain antibodies againsts the patient's blood so adjectives the antibodies in the transfusion will verbs the patient's blood.
A patient beside blood group AB+ is a universal receiver who could have any blood group because they own all the antigens and and so not the antibodies.
Hope this helps a bit
to craft sure that the blood group, Rh factor and the other antigen status matches and near is no reaction if the blood types be transfused.
