Hemoglobin A_I (Hb A_I) levels were measured in 103 diabetic patients. It was found that the Hb As levels were significantly correlated with the FBS levels before 4 and 6 weeks.
When the FBS levels before 4 weeks'were matched, no significant relations were observed beteween Hb As levels and administration of insulin or hypoglycemic agents, age, sex, duration of diabetes mellitus, diabetic complications (retinopathy, nephropathy, neuropathy), obesity, blood pressure, smoking, serum HDL-cholesterol levels or lecithin-cholesterol acyltransferase activity.
It is concluded that Hb As levels may represent a good index of FBS before 4-6 weeks in diabetics.
