We currently flag high at 42mmol/mol.
This raises an interesting topic. GP's (and hospital clinicians) are increasingly reliant on results being flagged as "abnormal" in their results systems to bring them to their attention. Results can easily be missed where flags are not present or not set as the clinician would expect. There are many tests to which flags cannot be reliably applied e.g. sex hormones and others where multiple cut-offs are applicable where a simple two flag approach (high/low) may not be appropriate e.g. A1c, cholesterol. I'd be interested to know what approaches other labs are using to reduce this risk?

Now that HbA1c is increasingly being used for diagnosis of diabetes mellitus as well as for monitoring of glycaemic control, are any laboratories now reporting it with a reference range, and if so what range is being used? Some GPs locally are concerned about missing raised HbA1c results in individuals not known to be diabetic if they are not flagged.
Any replies (to the mailbase or to me directly) would be appreciated.
