title: Permanent records of microchromatography of hemoglobins.
abstract: In the general hematology laboratory, quantitation of hemoglobin A2 by the microchromatographic method is superior to the method of elution from cellulose acetate membranes. A permanent record of microchromatographic patterns for the detection of hemoglobins S and C at birth can be easily obtained by using a photocopying machine and a flat mirror. These copies can be stored for comparison with definitive results when the children are retested at 6 months of age or later.
