I have a feeling that when you take FBS test fasting 8 hours results more glucose in the sample than taking a test fasting 12 hours.
Have you noticed this?

It's hard to say. When your BG gets low the body starts releasing more from storage, and presumably you get into this game at around the 8-hour stage, so the test is measuring several things at once. At 12 hours it's measuring this release control as much as it is insulin levels. Any one test is going to be plus or minus 5% or 10% or more. It may even depend on just what you ate for your last meal, or meals. And on how much exercise you got between the last meal and the test. Walk a mile and do a few pushups just before the test and it will likely lower the number by 5% or more.
Those of us who test before each meal, can see if the numbers are consistent from day to day, and if you have some regularity in carb consumption and exercise, the numbers tend to settle in a narrow range. I purposely do NOT exercise before my morning number, just to try to get a more meaningful reading. But I haven't particularly noticed any difference in the length of the fast, which probably varies between about 8 hours (from a small snack at worst) and over 12 hours.

Nope and really these should not be the only tests you have done because the results do not give the full picture.
A1c is better so don't know why they wouldn't give you that as well

Fasting is a great way to lower your glucose levels down. The more you do it, the more you force your body to get glucose from somewhere else (liver fat, body fat, etc..) I think it is normal to have more glucose after 8 hours in the sample because, 4 hours is a lot of time for the glucose to spread around the body. Especially if you drink plenty of water. Also, if your body has lots and lots of quantities of sugar in the tissues, the sample is not really indicative of the actual reality.
