I have an 18 yo Paint Gelding that has been losing weight and we can't find reasons. Blood was drawn Friday and some results are high some low. Any ideas? HCT Low 31, Fibrinogen 0.4 high normal, MCHC High 39.4, Albumin Low 3.1, Calcium Low 11.1, CK High 475. Anyone have any information. Wormed reg, teeth floated 3 months ago, feeding Senior feed etc. Thanks, KIM
