Your question is not clear especially the second sentence. For pre-diabetic status, you are safe if you can keep HbA1C less than 6.5%. You are still safe if your sugar level is less than 140 or even below 160 before bedtime which I assume you have your dinner 2 hours before. By my opinion, HbA1C is probably a better marker than fasting blood sugar for monitoring pre-diabetic condition.
