Important Information – HbA1c Blood Test Accuracy

NNUH Executive Managing Director Tracey Bleakley said: “Following updated national guidance, we are working closely with our Integrated Care Board (ICB) colleagues to determine the number of GP patients who may have received an incorrect diabetes diagnosis during the period 10 June 2024 to 25 November 2025.

Initial investigations showed that many people within that timeframe have since had a routine retest and were not affected.

We are now continuing our work with the ICB to develop a system to call back those who need to be retested. Investigations are still ongoing as to the numbers involved. The equipment is no longer used at the NNUH due to a routine equipment upgrade.”
