Fasting Glucose Levels?

I went for a follow-up appointment with my RE from my Laprascopy last month. She was going over some of the lab work and noted that my fasting glucose was 4.2. She said "Wow, that's low. That's really low. I wonder if the Met is doing that." She said would test it again in a couple of weeks. This was from a blood draw done on a Monday. I didn't eat anything after 10pm the night before and she told me not to take my Met Sunday night. I went in first thing Monday morning to have the blood drawn.

Everything I find about glucose levels are starting around 70 and go up. I'm confused. Am I looking at the wrong things or is that really low?! Wouldn't you think she would want to look into it more??

Blood sugar levels are usually given in U.S. units of "mg/dl"; the European units are "mmol/L". It could be your results were given using the latter units. A reading of 4.2 would translate to 75.
It could also be that you were actually looking at an HBA1c test (which shows an average blood sugar over the past 2-3 months). An HBA1c of 4.2 translates to a blood glucose reading of 72.

So that would mean I would fall in the low end of normal and that is good, right? Thank you Linda.
