Can fasting insulin levels be too low?

I heard on a podcast recently that one’s fasting insulin level can be a valuable number to know, so for $30 I requested to have mine tested. The results:

INSULIN: 2.6 NORMAL: 2.0-19.6 uIU/mL

It was surprisingly low given how many carbs and sugars I eat. My understanding is that anything below 3.0 is supposedly difficult to achieve, and means I’m insulin sensitive. Which I guess is good, since the other end of the spectrum - insulin-resistant - is the realm of diabetes.

But it’s been hard to find info on whether this level can be too low, and if so what it means. Does anyone have insight?
