Iron deficiency anemia is not simply a low hemoglobin result, a low serum iron result, or a reason to take an iron supplement indefinitely. The diagnosis contains two connected findings: iron deficiency and anemia. The […]

CBC and anemia blood tests evaluate the number, size, and distribution of blood cells and help organize common anemia and blood-cell patterns.1 A complete blood count with differential and platelets measures red cells, hemoglobin, hematocrit, […]
