Six months of continuous glucose monitoring data and concurrent laboratory HbA(1c) were evaluated from 51 type 1 diabetes (T1D) and 80 type 2 diabetes (T2D) patients. Red blood cell (RBC) lifespan was estimated using a kinetic model of glucose and HbA(1c), allowing the calculation of person-specific adjusted HbA(1c) (aHbA(1c)). Median (IQR) RBC lifespan was 100 (86-102) and 100 (83-101) days in T1D and T2D, respectively. The median (IQR) absolute difference between aHbA(1c) and laboratory HbA(1c) was 3.9 (3.0-14.3) mmol/mol [0.4 (0.3-1.3%)] in T1D and 5.3 (4.1-22.5) mmol/mol [0.5 (0.4-2.0%)] in T2D. aHbA(1c) and laboratory HbA(1c) showed clinically relevant differences. This suggests that the widely used measurement of HbA(1c) can underestimate or overestimate diabetes complication risks, which may have future clinical implications.<p> Addressing shortfalls of laboratory HbA(1c) using a model that incorporates red cell lifespan Monitoring, Physiologic 10 2022-02-21T22:48:57.408-06:00 10.7554/eLife.69456 18779
