What usually happens next
Call your doctor soon rather than waiting for a routine visit, and sooner if you have heavy thirst, frequent urination, weight loss you can't explain, or blurred vision.
A result this high is confirmed and acted on quickly, usually with a treatment plan rather than a wait-and-see.
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 10.5% good?
10.5% 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 10.5%?
About 255 mg/dL (14.1 mmol/L). In the ADAG study, 95% of people with this A1C had an average between 205 to 298 mg/dL.
What is 10.5% in mmol/mol?
91 mmol/mol. Many countries print A1C in mmol/mol (the IFCC unit) rather than percent.
