My fasting glucose is 82 (ref. range 70-100). my hba1c is 5.0(range 4.3-5.6) but my estimated average glucose is low at 96.8 (ref. range 97.0-140).is this concerning! my doctor said my bloodwork was all fine but is low estimated average glucose ok?

I agree with your physician and wouldn't worry about a borderline result of estimated average glucose.

Yes, all your numbers look great. If you are worried about hypoglycemia you might ask your doctor to prescribe you a continuous glucose monitor for two weeks to check your "time in range" and then your time below the optimal range. You might also ask yourself if you are having any symptoms of low blood sugar, like shaking or headache, and check your blood sugar to see if it's low or not.
