What usually happens next
If you have no risk factors, the ADA suggests screening from age 35 and repeating about every 3 years.
If you have risk factors (overweight, a family history, high blood pressure, past gestational diabetes), your clinician may test more often.
When an A1C can read wrong
A1C counts sugar stuck to red blood cells over their roughly three-month life, so anything that changes how long those cells live can move it without your glucose changing: anaemia, iron deficiency, kidney disease, pregnancy, a recent blood transfusion, and some haemoglobin variants. If your A1C and your glucose readings don't agree, that's usually why, and a fasting glucose or fructosamine can settle it.

Questions
Is an A1C of 5.0% good?
Yes: 5.0% is under 5.7%, the line the ADA uses for a typical A1C. It's one number, read with your fasting glucose and risk factors.
What average blood sugar is an A1C of 5.0%?
About 97 mg/dL (5.4 mmol/L). In the ADAG study, 95% of people with this A1C had an average between 76 to 120 mg/dL.
What is 5.0% in mmol/mol?
31 mmol/mol. Many countries print A1C in mmol/mol (the IFCC unit) rather than percent.
Worked out by LifeFrom from the ADA standards and the ADAG study, and not yet reviewed by a clinician. For your own understanding: only a lab test, read by your clinician, diagnoses anything.
