¿Qué Mide la Prueba de CBC?

The CBC with differential is one of the most commonly ordered blood tests. It measures your red blood cells (oxygen carriers), white blood cells (immune system), and platelets (clotting). The "differential" breaks down your white blood cells into five types (neutrophils, lymphocytes, monocytes, eosinophils, basophils), helping identify infections, allergies, and blood disorders.
