Should i be concerned about a fasting glucose lvl of 96. from high 80's a year ago. is it possible that somthing could have thown the test off a littl?

Yes need to follow: B"sd both levels are normal, but should continue to monitor, also would check after meals and have a HgbA1c done. You might also want to review your weight, diet and exercise situation. Take into consideration family history. It is best to control diabetes while it is still pre-diabetes and prevent or slow the onset of diabetes. Happy to discuss details.
