Sickle-Cell Anemia and Other Hemoglobinopathies

Abstract

Abstract Since blood spots on filter paper are routinely collected in many areas for phenylketonuria testing of newborn infants, we developed several methods for detecting sickle-cell disease and other hemoglobinopathies using this type of specimen. Simple, inexpensive modifications of cellulose acetate electrophoresis plus citrate-agar and globin-chain electrophoresis are employed, permitting one technician to screen as many as 500 specimens per day at a material cost of $0.03 per specimen.
