What usually happens next
One result isn't a diagnosis: the ADA confirms it with a second abnormal test (a repeat A1C, or a fasting glucose) unless symptoms make it clear.
Bring the result to your doctor, who will look at it with your fasting glucose, kidney function and blood pressure.
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 8.6% good?
8.6% is in the diabetes range (6.5% or higher). A second test confirms it, and your doctor reads it with your other results.
What average blood sugar is an A1C of 8.6%?
About 200 mg/dL (11.1 mmol/L). In the ADAG study, 95% of people with this A1C had an average between 161 to 236 mg/dL.
What is 8.6% in mmol/mol?
70 mmol/mol. Many countries print A1C in mmol/mol (the IFCC unit) rather than percent.
