Hemoglobinopathies, G6PD deficiency, and hereditary elliptocytosis in Bahrain.

The native population of Bahrain has a high prevalence of hemoglobinopathies and G6PD deficiency, probably as a result of past malarial endemism. We used the Biorad-Variant hemoglobin testing system for primary screening of hemoglobinopathies in 20,000 individuals. Hemoglobin abnormalities were detected in 7,206 (36.3%) cases.
