An Automated Filter Paper Dithionite Test for the Detection of Hemoglobin S

The automated dithionite test for the detection of hemoglobin S has been modified for use with AutoAnalyzers having a filter paper read-out. This method was compared with results of hemoglobin electrophoresis in 425 individuals, of whom 58 were positive for hemoglobin S. The two methods were in complete agreement. The automated filter paper dithionite test is a rapid, economical, accurate method for detection of hemoglobin S and could be easily incorporated into currently available mass screening equipment.
