Instructions This assay provides accurate results for hemoglobin A1c in the presence of hemoglobin A and the most common heterozygous hemoglobin variants (HbS, HbC, HbD, HbE, and HbF <30%). In patients with known homozygous and double heterozygous hemoglobin variants, hemoglobin A is absent. In such situations, measurement of long-term glycemic control should be monitored with an alternative assay.
