What is another word for blood typing?
Pronunciation: [blˈʌd tˈa͡ɪpɪŋ] (IPA) 
Blood typing refers to the process of determining an individual's blood group. Synonyms for this term include blood grouping, blood classification, and blood typing test. It is a crucial test conducted before a blood transfusion or organ transplant to ensure compatibility between the donor and recipient. The four main blood groups are A, B, AB, and O, with each group having a different antigen on the red blood cells. Blood typing can also reveal Rh factor, which indicates whether a person's blood is Rh-positive or Rh-negative. Knowing the blood type is crucial to prevent any possible blood transfusion reactions that could be fatal.
