Final answer:
A Complete Blood Count (CBC) is a blood test that measures various components of blood including WBC, RBC, hemoglobin, hematocrit, and platelets. The hematocrit is the percentage of RBCs in a blood sample, which is determined by spinning the blood in a centrifuge. The formed elements of blood include RBCs, WBCs, and platelets, with WBCs primarily involved in the immune response.
