Is it possible that the black samples are coming from people who have tattoos? I know in the heavily tatted cadavers, the lymphatic fluid is grey/black. The ink gets stuck and circulates. Idk anything about the color patterns of bilirubin but it would be really freaking interesting if that were why your samples were black.
