Normal A1C, slightly high fasting blood glucose. Should I be worried? Stats: White male, 34, 6 ft, 185 lbs. Good cholesterol and blood pressure. Grandmother on dad's side had diabetes, no other family history.  

In the past year, I've had three FBG tests: 

Feb '18 = 106

June '18 = 101

Feb '19 = 98

I've also had two A1c tests (the first one requested by my doctor as a precaution after my 106 FBG): 

June '18 = 5.1

Feb '19 = 4.9

So my A1C is well in the normal/good range, but my FBG is hanging around the low end of prediabetes. My doctor doesnt seem concerned, but is this unusual? Is the FBG test more "important" than the A1c, or vice versa?
