Introduction Patients included in Diabetes management programmes benefit from a reduced risk of
secondary complications. Measuring Glucose and HbA1c are essential for Diabetes management
and POC testing during routine consultation can improve monitoring.
We compared the POCT system ALLEGRO® to our standard measurement method on TOSOH G8
to evaluate the performance of the POCT system.
Material/Methods HbA1c in venous whole blood (EDTA) from 81 patient samples was analyzed by TOSOH
G8 in routine patient care. Subsequently the HbA1c was analyzed by the ALLEGRO system.
Method comparison was calculated by Passing-Bablok and Bland-Altmann.
Results Values spread over the measuring range as 36 % (N=30) were in normal range, 25 %
(N=21) in lower and 36 % (N=30) in higher range.
Total correlation for all results was r = 0,989, the mean difference was -0,11 % with
a slope of -0,11 and an intercept of 0,06.
Conclusion Overall a good correlation between TOSOH G8 and the ALLEGRO was found. Particularly
in higher range a good agreement of HbA1c was seen between both methods. In summary
ALLEGRO is suitable to monitor HbA1c in Diabetes mellitus.
