. However, the significance of an HbA1c value of 6.5% for a 60-year-old man depends on various factors such as his medical history, overall health, and other risk factors.According to a study, the HbA1c cut-point of 6.5% was associated with 3.78% false-negative predictions, while the majority of the false-negative patients had borderline fasting plasma glucose (FPG) and HbA1c, and therefore belonged to the at-risk category on the basis of HbA1c alone criteria

. Another study found that for people aged ≥60 years, the upper reference limit for HbA1c was 47.5 mmol/mol (6.5%)
