Free T4 (fT4) Test for Dogs & Cats – At Home Pet Care
The Free T4 (fT4) test measures the level of unbound, biologically active thyroxine hormone in the blood of dogs and cats. Unlike Total T4, Free T4 is not affected by protein binding, making it a more accurate indicator of thyroid function. This test is essential for diagnosing hypothyroidism in dogs and hyperthyroidism in cats with greater accuracy.
Why is the Free T4 Test Important for Pets?
Free T4 is the metabolically active form of thyroxine. In dogs, low fT4 levels confirm hypothyroidism, especially in cases where Total T4 is borderline or suppressed by non-thyroidal illness. In cats, elevated fT4 is the most reliable indicator of hyperthyroidism, particularly in cats with high-normal Total T4 levels. The fT4 by equilibrium dialysis (ED) is considered the gold standard thyroid test in veterinary medicine.

– Hypothyroidism in dogs
