Blood Tests and Twelve hour fast

I was required to take medical tests for insurance. The doctors indicated that I need to fast for twelve hours prior the tests. Today, during the tests I enquired about the reason.

The results of some tests change following digestion of food. For example, when we eat lots of sweets, the sugar quantity in blood will increase. This means we will see different results depending on the time from last meal. By fasting for twelve hours, we provide doctors with base results that can be compared over time.
