Actually it is…If you went to the gym and took a blood sample right away. Yes it would be high and i have seen results up untill 2000 after physical exercise, which is completely normal.
Why bother with blood pressure reference ranges if it rises while simply walking? Or why bother with Testosteron reference ranges if it fluctuates during day…Its simply becuz, you have to define when and how to take the blood sample for it to be meaningful. Would my potassium measurement in blood be high if i take a supplement containing it, ofcourse it would. BUT that doesn’t reflect that i have a problem with my kidneys etc…
Now wehster Fin raises CK, i dont know, i havent done my research on that but that wouldnt surprise me at all, but i would never base any medical aussumption that something with the OP is wrong just becuz his CK 3 points higher without controlling it more than once and making sure, he didnt make any excercise or muscular effort before taking the measurement.
