3. Avoid heavy training or physical activity one day before
A small physical activity like stretching, yoga, or a simple walk in the park won’t affect anything. It is recommended to resume your usual daily routine of physical activities before blood tests.
On the other hand, if you plan on working a tad hard, we advise you to postpone it for two or three days after the tests. Why? Because intense exercise will induce considerable changes in the amounts of inflammatory markers in the blood as well as lipids, white blood cells, glucose, and red blood cells.
Additionally, before the test itself, it is a good idea to discuss the fitness plan with your doctor.

Thank you for everything from the girl with many problems.
I’ve only heard of some of the suggestions when fasting was necessary. I was told for most tests you want things as normal as possible so they can see what your levels are under normal circumstances.
My doctor told me to fast before raking sugar test and it was when they were doing my annual test for everything i was told to not eat/drink anything except water after 10pm the night before my blood work at 8am
Same from my doctor. The suggestion here “It is recommended to have lab tests performed either before or 10–14 days after taking any medications you are thinking about taking” is wrong.
I had a doctor send me for a blood test and never asked what I ate or drank and when I did. Needless to say it was a one time visit with that incompetent sob. He also told me to stop taking supplements that it was a waste of money. The guy was an idiot.
Re: page 4 “… postpone it for two or three days after the tests.” Should this be “before” the tests?
Yes. I believe they meant prior to testing.
Seems to be a typo. Probably due to starvation before going to a blood test next day.
Interesting
Don’t take biotin – vitamin B6 – before a Thyroid test
(TSH). It can cause the TSH test to test high.
