Total T4 alone is often misleading

· Overdiagnoses hypothyroidism in the presence of non-thyroidal illness or use of certain drugs

· Underdiagnoses hyperthyroidism in cats or from thyroxine overdosage

· Inaccurately assesses adequacy of thyroxine therapy

· Fails to detect autoimmune thyroiditis

· Minimal testing is T4 + free T4, except thyroiditis will still not be detected

· For cats, but not dogs, cTSH can be helpful to identify concurrent hyperthyroidism and renal failure
