Exp 1 and Exp 2 are the closest to the worst: Exp 1 is characterized by small areas of the peaks located both in the first (negative scores on [PC.sub.2]) and in the second (negative scores on [PC.sub.1]) part of the chromatogram. Exp 8 and Exp 4 are the best ones for what regards [PC.sub.1] (larger areas for the peaks of the second part of the chromatogram), while Exp 7 is the best one for what regards the peaks eluting in the first half of the chromatogram.

HPLC is used as the primary method for HbA1c analysis in many laboratories in New Zealand and an abnormal chromatogram trace does not give specific result of the precise variant, but can elucidate different haemoglobins by means of their physicochemical characteristics, in the context of clinical and family history, ethnic origin, blood count and blood film (4).
