HbA1c is an established marker of glycaemia that is usually tested on venous blood in the laboratory but can also be measured on point of care test (POCT) devices. To date, UK guidance has not fully supported the use of POCT HbA1c for diagnosis of diabetes or categorisation of people in high risk states, due to the combined issues of accuracy and precision of currently available devices. Guidance has therefore suggested that POCT HbA1c should only be considered where performance of these devices is comparable to laboratory assays, and delivery must be implemented within an appropriate quality framework.


In this document we discuss the advantages and disadvantages of POCT HbA1c for use in the NHS Diabetes Prevention Programme and specify recommendations for its use.
