how does creatine affect your blood tests?

[legs]

i heard creatine may raise some blood levels like liver, so if im going to take bloods what would be out of proportion, and how long should someone stop supplementing creatine be4 he goes for bloods in order for his bloods to be normal again?

kidney function, more specifically creatinine count. stop it 2 weeks prior...my creatinine levels are always above the range even when off creatine. it's from the high protein diet.
