What is an incompatible transfusion?

What is an incompatible transfusion?

What is an ABO incompatibility reaction? An ABO incompatibility reaction can occur if you receive the wrong type of blood during a blood transfusion. It’s a rare but serious and potentially fatal response to incompatible blood by your immune system.

What is the meaning of alloimmunization?

Alloimmunization is defined as an immune response to foreign antigens after exposure to genetically different cells or tissues. Although alloimmunization is a natural event during pregnancy, frequently it is the undesirable outcome of a blood transfusionand/or transplant.

Why should platelets not be cross matched?

If there are no problems (no clumping), a cross-match takes about 30 minutes. A cross-match is usually not needed for a platelet or plasma transfusion unless the platelets look like they could contain some red blood cells.

What is the difference between Rh incompatibility and ABO incompatibility?

For ABO incompatibility, the effects are usually mild and go away with time, but with Rh incompatibility, the consequences can be very serious. A baby can be born with severe jaundice, characterized by a buildup of a substance called bilirubin.

Is O+ and AB+ compatible?

O positive red blood cells are not universally compatible to all types, but they are compatible to any red blood cells that are positive (A+, B+, O+, AB+).

What blood groups should not marry?

A person having Rh factor in blood is called Rh positive whereas that who does not carry this protein in the blood is called Rh negative. Marriage should be avoided in between Rh negative female & Rh positive male. This can be fatal for the mother as well as the baby of such parents.

What blood type are not compatible for pregnancy?

When a mother-to-be and father-to-be are not both positive or negative for Rh factor, it’s called Rh incompatibility. For example: If a woman who is Rh negative and a man who is Rh positive conceive a baby, the fetus may have Rh-positive blood, inherited from the father.

What causes alloimmunization?

Introduction: Alloimmunization is caused by exposure to erythrocytes from a donor that expresses blood group antigens other than those of the recipient and is related to processes that alter the balance of the immune system.

What are cross matched platelets?

Cross-matching platelets is a method of selecting compatible platelets for patients with HT, in particular, in hospitals where access to large panels of HLA-typed platelet donors is limited.

Do platelets need to be Rh compatible?

Platelets do not express Rh antigens, but platelet components contain residual intact RBCs or fragments that can result in alloimmunization to RBC antigens, including RhD.
