Stress. Low free t3 (liothyronine) often correlates with adrenal stress/fatigue or low temperature syndrome. Checking your reverse t3 (liothyronine) level can help. A high reverse t3 (liothyronine) is suggestive of this diagnosis.

Treatment involves getting to the root of the problem and reducing stress.
Probable hypothyroid. The free t4, not free T3 (liothyronine) test, is necessary here. Positive antibodies indicate hashimoto's thyroiditis, the most common cause of hypothyroidism. It may just be early in the process to cause the TSH to be elevated.
