If the levels are slightly outside the normal range, should I seek treatment right away?

If it is borderline, try improving your lifestyle first and consult with your doctor to make a follow-up plan.

Which is more important: fasting blood sugar or postprandial blood sugar?

Both are important. Fasting blood sugar is the baseline state, and postprandial blood sugar is the ability to process sugar.

Where should I keep my test results?

Keeping your results on file each year is a good way to track changes over time.
