state cross matching of blood
Answers
Answer:
=> In transfusion medicine, cross-matching or cross-matching (part of series of steps in blood compatibility tests) is testing before a blood transfusion to determine if the donor's blood is compatible with the blood of an intended recipient. Cross-matching is also used to determine compatibility between a donor and recipient in organ transplantation. Compatibility is determined through matching of different blood group systems, the most important of which are the ABO and Rh system, and/or by directly testing for the presence of antibodies against the antigens in a sample of donor blood or other tissue.
=> Cross-matching is done by a certified laboratory technologist in a medical laboratory. It can be done electronically with a database if a patient has previously been tested, or serologically by physical testing if not. Simpler tests may be used to determine blood type only (known as blood typing), or to screen for antibodies only (see indirect Coombs test).
