I'm wondering if you mean creatinine, as blood work doesn't measure keratin. The increase in creatinine can indicate kidney issues, and something like kidney failure can cause significant weight loss. Yes, you can give Retchi the deworming treatment but I don't think the chemistry changes are related to any worms.
