Description

A CTV3 codelist for patients receiving monitoring of glycated haemoglobin (HbA1c) tests using reference methods standardised by the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC).

Note that for tests before 2018, test values in the East region appear to be recorded on a different scale (approximately 4 to 8-times greater than mean values in other regions). This issue is being investigated.

Methodology

Codes under the CTV3 concept for IFCC-standardised HbA1c were included.
