Automatic measurement of hemoglobin F in blood obtained from patients with hemoglobin E/E and beta-thalassemia/hemoglobin/E.

ABSTRACT

This paper presents an automated determination of hemoglobin (Hb) F in Hb E/E disease using Hi-Auto A1c. Blood specimens collected in Bangkok were frozen, and sent to Japan by air mail for the determination. The automatically determined values showed a high correlation with the values obtained by the classical alkali denaturation method. Hb E/E cases showed 4.24 +/- 1.75% of Hb F. On the other hand, Hb, Hct, MCV and MCH in the disease samples were lower than in the controls, but higher than those of beta-thalassemia/HbE disease. From the results it was concluded that Hb E/E could be differentiated from beta-thalassemia/HbE by combination of Hb F value and MCH or Hb in CBC.
