β FAQ: COMMON QUESTIONS
Q: How is A1C calculated?
A: We use the standardized relationship between HbA1c and blood glucose levels derived from the ADAG study. You can switch modes to convert blood sugar to A1C or vice versa.
Q: What is a dangerous level of A1C?
A: Generally, an A1C above 9% indicates poor control. Our tool highlights the prediabetes range versus critical levels to help you stay safe.
