How many days off training before blood test

[LeeroyMatinta]

I lifted weights on Monday, but wanted to do a blood test on thursday morning and test bunch of things (liver, kidney, etc). I read that lifting weights falsely elevates liver values and that you should take ~7 days off before a blood test.

Do you think itll be fine or should I do the blood test next thursday and dont lift for 5-7 days prior?

From what I know, liver enzymes alt/ast are usually affected by intense exercise causing elevation due to muscle stress. Levels may start to normalize within 3 days, but can remain elevated for up to 7 days especially after heavy workouts. It is similar for CK (creatine kinase), will show higher muscle damage markers for 5-7 days after heavy work. FWIW.

You are so smart,, Now go to "the new member thread" and introduce yourself to the Meso community as is proper protocol here at Meso Rx , js

If you want to see cleaner numbers, 2-3 days. If you understand what should be elevated and are good with it, no need to take days off.

0 days to see actual situation.
1-7 days to allow muscle soreness and other factors to not give false positives.
14+ days to see "normie" levels (so in reference with a person, that does not workout).

where did you come up with these numbers? Is there some useful article for reference or just some random information thought up by you?

My personal experience, when I needed to cool off my body to pass health tests for my job (had raised ast, alt, CK, LDH because of intense training. Creatinine dropped after stopping creatine 2 weeks before).
Of course, if you are not healthy, then much longer.

If heavy set of squats is 200 pounds it is likley that there will be little change on blood values. If a person is squatting 500+ then it is a different story. I can get more elevation in my blood panels form a heavy protein intake then moderate lifting as the same enzyme they test for is the same enzyme released from digesting protein. I really don't take time off from lifting as i know what to expect from it with testing.
