D
T/F : iron deficiency typically occurs in horses older than 15 that have no access to soil or a pasture
False- typically foals with poor quality milk AND no access to soil/pasture. We do not give iron dextran to these cases as it causes acute heptatotoxicity
Relearive polycythemia is (more common/ less common/ just as common) as absolute polycythemia
More common
T/F: a systolic heart murmur is common in anemic patients
True
T/F: Reticulocyte count in a blood test is the most accurate way to diagnose regenerative vs non regenerative anemia in a horse
