Much more information would be required in order to make any sense or use of blood results, a summary of what has been concerning you, her signs and symptoms and response to any previous treatment i would be required at a minimum. It is unusual to have a high RBC/HCT (more than normal red blood cells )and low MCH/MCHC (usually found when recovering from anaemia). This may indicate the red blood cell production process is gone wrong and an examination of the cells under a microscope by a specialist pathologist and possible bone marrow biopsy may be required. Occasionally accidental exposure to human medications used to promote blood production can produce similar results
