[Use of the determination of "fast" hemoglobins for surveillance and diagnosis of diabetes mellitus].

Personal results in the assay of "fast hemoglobins" in diabetics and normal controls are reported. For the latter, a normal range of 5.45--8.25% HbA1 has been determined. Correlation between HbA1 and fasting blood sugar was found for diabetics, the correlation being at its highest for a group of diabetics with rather constant fasting blood sugar. From the results of this group it proved possible to calculate a simple system for the evaluation of therapy. The diagnostic of HbA1 is limited, since concentrations remain normal in mild diabetics with normal fasting blood sugar.
