in our studies , the polymer fraction in sickle red cells was determined from reported mean values for hemoglobin composition and mean corpuscular hemoglobin concentration ( mchc ) in 12 groups of patients with sickle hemoglobinopathies ( homozygotes for hbs , with and without coexistent alpha-thalassemia or various forms of the hereditary persistence of fetal hemoglobin [ hpfh ] , beta+- , beta 0- , and delta beta-thalassemia , and heterozygotes for hbs with hba ) .
