The Queensland (Qld) proof of concept study was designed to determine whether pathology data would provide a geo-epidemiological guide to diabetes prevalence in Qld. The data captured results from 52% of the population, provided information on 27 % (25-34) 36% (35-44) 51% (45-54) 67% (55-64) 82% (65-74) and 92% (>75) of the Qld population . Using the Qld population as the denominator we showed a minimum prevalence of  5% based on this 52% population. Of concern was the 2.3% rate of individuals who had not had a HbA1c but had FBGL > 7mmol or RBGL >/=11.1 mmol. This totaled 62500 individuals. Of these there were 15000 who had numerous abnormal BGL in the diabetic range yet no HbA1c to suggest a diagnosis was made. More than 65% of these were over 55 years of age.We acknowledge that there is lack of clinical data and these observations are made purely on de-identified pathology data extracted from pathology laboratories. A delay in diagnosis of diabetes may be associated with a prolonged glucolipo toxicity and metabolic consequences therein. At a population health level these delays will magnify the already epidemic dilemma Australia faces. Further, these observations raise the issue of  health care professional responses to the abnormal BGL's and what systems could be implemented to contain the delay in diagnosis. Suggestions include (1) that  pathology laboratories have an automatic message with the abnormal results suggesting that if not diagnosed diabetes be considered and (2) practice software be improved to allow more prompts to action with clearly abnormal pathology. These are two simple interventions.  Further discussion and investigation is warranted, in particular systems to promote the message for vigilant awareness at a community and individual practitioner level.
