I was thinking about the flukes and worms killing the liver, and primary sclerosing Cholangitis is coming up in my head.. and scarring, and oh many liver-troubles. I am more worried about seconadary issues (organ damage) than the worms at times. I hope the SCIO can show when damage is growing. This machine is gold, Im getting one as soon as I start to work! How can anyone be without this unit!
