For example, 1.0 ng/mL is equivalent to 100 ng/dL. Please use caution when comparing current results to historical reports. The concentration of T3 in serum or plasma is within the reference range for normal healthy animals. The concentration of T3 is low normal or low in hypothyroid animals. Clinically hypothyroid dogs with unexpectedly high T3 concentrations may have autoantibodies against thyroid hormones. The thyroglobulin autoantibody test is suggested in these cases. Clinically hyperthyroid animals will have high normal or high T3 concentrations. Rarely animals becoming hypothyroid will have elevated T3 until T4 is very low, then both decrease. This is most common in young horses in training and usually self corrects with treatment. Animals on anti-inflammatories, antibiotics or with chronic illness may have falsely decreased total T3. Animals given supplements containing kelp may have elevated results and show clinical signs of hyperthyroidism. Treatment is best monitored by testing 4 to 6 hour post-treatment. Canines with positive autoantibody tests should be tested for free T4 by dialysis.
