Cross-matching is a critical safety procedure in both Brazilian and American healthcare systems before blood transfusions. In Brazil, it is routinely performed at blood banks (bancos de sangue) and hospitals before any transfusion procedure. The term is universally understood among medical professionals across Portuguese and English-speaking countries. This procedure became standard practice globally after the discovery of blood groups and is now a mandatory legal requirement in most countries to prevent transfusion-related complications.
