Abstract
Acquired hemolytic disease (AHD) is an auto-immune disease characterized primarily by a shortened life-span and rapid regeneration of red cells. Idiopathic or secondary AHD is suspected any time a chronically anemic patient also has a chronically elevated reticulocyte count. It is diagnosed by demonstrating the immune mechanism by the antiglobulin test (Coombs' test) and is ordinarily controlled by corticosteroid therapy.
