Understand the Problem
The question is asking about the primary use of indirect antiglobulin tests (IAT) in a medical or laboratory context, likely relating to blood typing or detection of antibodies.
Answer
RBC phenotyping and in crossmatch screening for blood transfusion.
Indirect antiglobulin tests (IAT) are primarily used for RBC phenotyping and in crossmatch screening for blood transfusion. They are also used to detect circulating antibodies that could induce RBC hemolysis.
Answer for screen readers
Indirect antiglobulin tests (IAT) are primarily used for RBC phenotyping and in crossmatch screening for blood transfusion. They are also used to detect circulating antibodies that could induce RBC hemolysis.
More Information
The indirect antiglobulin test is crucial in blood transfusion compatibility testing because it ensures that donor blood does not carry harmful antibodies that could trigger immune responses in the recipient.
Tips
Students often confuse the indirect antiglobulin test with the direct antiglobulin test (DAT), which is used to test for antibodies coating the surface of red blood cells. Ensure you understand the difference between these two tests.
