...the gp, help.? I've had high alt levels for 12 weeks now, at the highest they were 544 and for the past 6/7 weeks they've stayed between 190 and 200. My bilirubin level was also 105 but that's normal now. I have had a scan and various blood tests for all kinds of hepatitis, viral infections and autoimmune diseases everything has come back clear, now my full blood count is low and I noticed on the latest blood test form the boxes were also ticked for bone blood test and renal blood test, what would these be for? As no one has explained anything to me and my alt levels just don't seem to be going down.
