yes it is mustard colored, it could be gilbert's but last time I got a liver panel done, it came back negative for all enzymes (they were not elevated), I tested negative for all hepatitis, and bilirubin was in normal range (though slightly above the median within normal)
I was told that I might have a congested liver/gall stones (though ultrasound came back clear)
i kinda think gilbert's is triggered by a congested liver state anyway...I have done 7 flush thus far, and always seem to get alot of sludge each time, with a couple of the flushes producing alot of stones
i`ll have to get another liver panel, as this one was about 1.5 years ago (but I have had the pale stool symptoms since I was 16 seven years ago)
