The measurement of glycated haemoglobin and serum fructosamine to asse
ss the recent glycaemic control of diabetic patients has become well e
stablished. Likewise, the monitoring of blood glucose using glucose te
st strips and meters has become popular in both the community and in t
he hospital inpatient environment. However, despite improvements in th
e methods of analysis, clinically inaccurate assessments of glycaemia
can still occur. Specific problems such as the lack of standardization
in assays are in the process of being resolved, but inherent difficul
ties associated with these measures remain. Clinicians should be aware
that these tests still need to be interpreted in conjunction with cli
nical prudence. (C) 1997 by John Wiley & Sons, Ltd.
