liver,lipids,thyroid,kidney functions. The test generally show the range for each. ex. (sgpt) 0-50 is in the normal range, if it comes in at 95 it will be put in a high column showing out of normal range. To answer your other question Yes even supplements can throw your values out of wack. One time I worked out before my blood test and my values were all screwed up, Doc said something about the dead cells caused by the trauma to the muscles showing up in the test. Maybe one of these guy's on here who's smarter than me can explain it better.....any way hope this helps....Oh yea! Best to leave the booze alone for a few days before the test.
