From what I understand I should get my blood-work taken while fasted, but I was wondering if I can still workout in the morning?
I actually do fasted training every morning (7:00 - 8:00), but should I skip it the morning of the test which is at 10:00?
The question being would it skew the results in some way?
22.02.12: Thanks everyone, will keep fasted and skip the training. Looking forward to actually seeing some numbers for the first time next week. I just wish I took a test before I started Paleo to see if there is that much of a change.
"Engaging in vigorous exercise just before your blood test can temporarily lower your cholesterol and triglyceride values, but a vigorous workout can also raise the level of a muscle enzyme called CPK. It's wise, therefore, to take a day off from intense workouts just before you take the test."
I'm getting my blood work done at 12:15 today! SUcks that I have to fast for 4 hours but I can handle it. ANyways I went for a run last night and then ate a ton of food haha im still pretty solid no hunger pangs yet. Good luck! Im looking to bring down my tc from 204 last june. Hoping for 190 range.
i am having cholesterol screening at work next week and the specifically state no food or exercise before the test. exercise affects blood sugar so probably affects cholesterol; maybe increases in response to the micro tears in the muscle? my guess is to wait till after the blood draw.
I would advise against it. You'd be surprised at the number of assumptions made in most blood work. They aren't actually measuring something in your blood, they're measuring something that correlates with what you want measured and then that's calibrated from other standard samples which assume "standard conditions". The one they talk about is the 4 hour fast, but they're also assuming your pre-test behavior is going to be like everyone else, and that means probably being sedentary.
