lab values

My daughter was diagnosed with indeterminate colitis 6 years ago. She is currently taking 12.5mg Methotrexate and 40 mg Humira every week. She generally feels ok-however, I think, she has just reset her concept of what is feeling " good". But, her lab values tell another story. Her platelet count is over 1 million, she is slightly anemic, CRP 60, Albumin 2.4, and her potassium is slightly elevated at 5.6, which is odd since potassium is absorbed in the colon which is wherre her disease is. Anyone have any experience with these sorts of lab values? Thanks!
