Comparison of HbA1c Measurements using 3 Methods in 75 Patients Referred to One Outpatient Department

Abstract: The mean IFCC standardized HbA from 75 people differs by up to 0.5% absolute between 4 laboratories. This difference is clinically significant and may lead to misdiagnosis and wrong treatment decisions, while HbA value from one patient were analyzed in different laboratories within a short time.

“…With regard to HbA1c, a previous analysis using the data of survey 2009/10 showed good accordance of self-reported HbA1c with clinical documentation [ 16 ]. Nevertheless, we were not able to account for different laboratory methods of HbA1c, which recently have been suggested to influence HbA1c results [ 41 ].…”

“…If the HbA1c value is notably high, e. g. 66 mmol/mol, the diabetes diagnosis is conclusive. In the HbA1c range of 42 to 97 mmol/ mol, it is not unusual to observe deviations between laboratories of 18 mmol/mol and higher [17]. However, in the range of an HbA1c value of 37 to 48 mmol/mol many of the patients studied (50 %) showed pathological plasma glucose values in an oral glucose tolerance test (oGTT).…”

“…8,2 % (66 mmol/ mol), dann ist die Diabetesdiagnose eindeutig. Nicht selten werden im HbA 1c -Bereich von 6 % bis 7 % (42 bis 53 mmol/mol) aber Abweichungen zwischen verschiedenen Laboratorien in einer Höhe von 0,5 % (18 mmol/mol) und mehr beobachtet [15]. Im Bereich eines HbA 1c -Werts von 5,5 -6,5 % (37 -48 mmol/mol) weisen viele der Untersuchten (ca.…”
