The microchromatographic measurement of fetal hemoglobin levels in hemoglobin C-associated conditions.
We report the microchromatographic estimation of fetal hemoglobin (Hb F) in 3 conditions associated with hemoglobin C: hemoglobin C-hereditary persistence of fetal hemoglobin (Hb C-HPFH), homozygous hemoglobin C disease, and hemoglobin SC disease. In the case of Hb C-HPFH (Case 1) the Hb F level by alkali denaturation was 32.5% while the Hb F level by microchromatography was 35.3%. In both cases of homozygous Hb C disease and Hb SC disease the Hb F level by alkali denaturation was less than 1% and the microchromatographic Hb F level was 0.7%. We conclude that microchromatographic methods for determination of Hb F levels can be employed in the Hb C-HPFH, homozygous Hb C, and Hb SC conditions. To our knowledge, the microchromatographic determination of Hb F levels has not been applied previously to the Hb C-HPFH condition or Hb C disease.
