Well a 6.0 and higher is considered pre-diabetes but to have some solid conclusions you need to see if you have a track of past results to look at. A single A1C result alone won't tell you if you have a present situation. There's also the other factors like family history, knowledge of your eating habits, lifestyle. Then of course if asked to fast before exams you should do so to obtain accurate results.
The first thing to do now is try an get a case history of lab results with A1C or budget for a series of send-a-way tests over a period of two months to three months. If your AIC comes back and you have a consistant track over 6.0 then it's time to consult a diabetes specialist.
Also ask for a train of Blood Glucose levels. there are two types to watch for...
Fasting blood sugar (FBS) measures blood glucose after you have not eaten for at least 8 hours. It often is the first test done to check for diabetes. Normal ranges are considered between 70 and 126 with best under 120.
2-hour postprandial blood sugar measures blood glucose exactly 2 hours after you eat a meal. Once again target numbers are under 120 down to 80.
