a simple rapid procedure for hemoglobin electrophoresis using a drop of dried blood on filter paper

a simple, rapid new technique is described for the electrophoresis of hemo­globin when screening large human populations. the method uses a drop of finger tip's blood dried on a thick filter paper as the specimen. the simplicity of the sampling, tagging, transportation and electrophoresis, provides a reliable procedure for surveys of large population. in our hand 200 specimens were screened during a working day by two technicians with a very good resolution of hemoglobin band. even small amount of fetal hemoglobin could be separated from normal adult hemoglobin by this technique. during last 8 months, 20,000 individua1s were screened by this technique and a number of known and unknown hemoglobin variants were detected which are reported elsewhere.
