IMO you should take your blood in a non-fasting state to get a true reading, because fasting is not what you usually do. You want your numbers to reflect your routine... what your blood looks like normally, instead of what it looks like under the artificially created fasting conditions.
I also think it unwise to skip your medication the day of the test, for the same reason.
When you get your results back, on the test write your weight, any symptoms you've been having, when your blood was drawn and when you took your meds. If you've been ill. Also any other medications you've been taking, including antibiotics.
Try to get tested under the same circumstances as much as possible, to reduce variables that can influence your numbers.
This way you can put your numbers in context.
The numbers on your blood work are dynamic, and for general reference only.
Putting too much emphasis on them is unwise... how you feel is waaay more important.
Just my opinion.
