Im not too sure abt these tests, but i think the last one has something to do with fats in the blood or cholesterol, ask the Doc, dont sit there worrying, make him/her explain them to you to put your mind at ease, read my 1st porst under high esr's and you will see why i say dont wait and worry, i was petrified for a week and the test was a mistake. But a week of sleepless nights is just not worth it, go ask ur Doc. Good luck
