elevated liver enzymes

[robint]

all the test have been negative to date, Enzymes still high, alk phos, alt,ast,now billirubin is elevated slightly, testing every week and going up about 30 points each time no drugs for 6 weeks. frustrated for we are at to possibilities, toxic liver that may have damaged a portion and continuing to progress or mets that are not obvious on ct. I cannot have mri, for expanders
i think we will repeat ultra sound. we are waiting to see if they will trend down, then schedule biopsys.

thanks
