Fbs 4.4, after 2 of eating 8.07.

Hello everyone, I just want to need your suggestion. So a month back I had done my blood tests without fasting and my glucose was high 8.07mmol and next day I was fasting for 8-10 hours and went to check, they pinned my finger took my blood and tested it was 4.4 mmol. Today again some diff doc saw my old blood reports and she was like my glucose is too high which shouldn't be, I even told her that later I checked with fasting stomach and it was 4.4 still she asked mw to go and check again. So can FBS 4.4 can be diabetic?
