HEMOGLOBINOPATHIES, HEMOGLOBINOPATHY
Glycosylated hemoglobin A1c (HbA1c) was assayed at Quest laboratory using direct enzymatic assay. Hemoglobinopathies, which vary by population, can make some HbA1c assays unreliable. Hb E is the hemoglobinopathy of most concern to this study because it is not uncommon in Southeast Asians. Therefore, we used a direct enzymatic assay because this method is unaffected analytically by Hb variants
