Why do normal HbA1c ranges vary by age?
The normal HbA1c range can vary by age due to several factors. As people age, their blood glucose control may become more difficult, leading to higher HbA1c levels. In addition, older adults may have other medical conditions that can affect their HbA1c levels. Furthermore, the normal range for HbA1c may also differ based on the specific guidelines used by different medical organizations. For example, the American Diabetes Association recommends a normal HbA1c range of less than 7% for adults, while the International Diabetes Federation suggests a normal range of 6.5% or less.
