Gallbladder
It took so long because they kept ordering ultra sounds which kept coming back negative for stones. I don't have them - or if I do they're very small and/or are in the exit tube only. The function test showed that in the given time my gallbladder only dumped 21% of the dye instead of the minimum of 50%. Luckily I'm not in continous pain - though I suppose that would have had doctor's attention quicker.
