Yeah I would stop if you're concerned until the labs come back. Nice thing about orals is the effects happen quickly. So stopping for a week wont really be the end of the world.
As for turning yellow and stuff. I have had elevated liver enzymes from catching hep A eating out, and I didn't turn yellow at all. I just had the shits for like 2 months straight and they were very foul smelling. I went to the doctor and they did labs and said I had hep A, and that they wanted to monitor my labs every 2 weeks until my body built up the antibodies for the hep A. They also said my enzymes were high and a bit of a concern but not an alarm. So I'm guess it is different person to person....but in my case I assume for me to turn yellow my liver would be pretty much shot or close to it. Like if you're yellow its beyond just stopping the drugs its time for serious measures.
