We have previously shown that microcytosis identified by the Model S Coulter Counter (Coulter Electronics, Inc., Hialeah, Florida) is a useful clue to the diagnosis of β-thalassemia trait, and we have recently completed a large screening program for microcytosis. Between March 1971 and October 1972, 1000 patients (about 1% of those having blood counts
