A simple finger-prick method of screening for abnormal hemoglobins.

Thambipillai, Shanthi, and Senewiratne, B.: A simple finger-prick method of screening for abnormal hemoglobins; Am J Clin Pathol 63: 836-840, 1975. Two simple methods of hemoglobin electrophoresis of samples obtained by finger prick are described. The methods do not involve venipuncutre, centrifugation, or the preparation of a hemolysate, and can be carried out on starch gel or cellulose acetate membranes. The specimen can be collected even by non-medical personnel and sent by post to the laboratory. Alternatively, electrophoresis can be carried out in the field and the results obtained within 20 minutes. Both methods are suitable for population screening and pediatric studies. The method will detect structurally abnormal hemoglobins only.
