If you are newly diagnosed with diabetes or prediabetes, the numbers can feel like a foreign language. Here is a plain-language breakdown of the terms you will hear most at our office.
A1C
Your A1C is a simple blood test that reflects your average blood sugar over roughly the past three months. It does not require fasting and is one of the most useful tools we have for tracking how well a management plan is working over time.
- Below 5.7% is generally considered normal
- 5.7% to 6.4% generally falls in the prediabetes range
- 6.5% or higher, confirmed on repeat testing, generally indicates diabetes
These ranges are general guidelines — your personal target should always be set with your care team.
Fasting Blood Glucose
This measures your blood sugar after at least eight hours without eating, typically drawn first thing in the morning during routine lab work. It gives a snapshot rather than an average, which is why it is often used alongside A1C.
Home Monitoring
If you check your blood sugar at home with a standard glucose meter, those daily readings help us see patterns — like whether mornings or evenings tend to run higher — that a single lab visit cannot capture. Bringing your log (or your meter) to appointments helps us fine-tune your plan together.
You do not need to memorize every term. Understanding the big picture — and asking questions when something is unclear — is what actually helps you manage diabetes day to day.
