Well this morn I had the bile salt test before eating breakfast but it takes a week to get a result. In the meantime they did another liver function test and said it was the same as yesterday - a bit higher than normal!? Yesterday a different doctor said it was ok. Apparently my levels are 60 when normal is up to 50 so its only slightly elevated. So they're going to keep a closer eye on me and do another liver function test on Tuesday to see if its going up.
