Cross matching
Cross matching
Cross matching (pronounced: /krɒs 'mætʃɪŋ/) is a crucial procedure in transfusion medicine that ensures compatibility between the donor's blood and the recipient's blood.
Etymology
The term "cross matching" is derived from the English words "cross," meaning to traverse, and "matching," which refers to the process of comparing for compatibility.
Procedure
Cross matching involves two main steps: the major crossmatch and the minor crossmatch. The major crossmatch tests the recipient's serum against the donor's red blood cells, while the minor crossmatch tests the donor's serum against the recipient's red blood cells.
Importance
Cross matching is vital in preventing transfusion reactions, which can occur if the recipient's immune system attacks the transfused blood cells. This can lead to serious complications, including hemolysis, anaphylaxis, and even death.
