Elevated thyroid antibody. But normal thyroid level? Is medicine needed?

Low free t3, (liothyronine) normal TSH and high tpo antibodies. What's this mean?

Low free t3, (liothyronine) normal TSH and high tpo antibodies. What's this mean?

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. ...Read more

High thyroglobulin & T3 (liothyronine) Free levels post thyroid lobectomy indicates what?

High thyroglobulin & T3 (liothyronine) Free levels  post thyroid lobectomy indicates what?

Thyroid: Something does not add up. Thyroglobulin may be high for a number of reasons and can be controlled if needed. I don't understand why free T3 (liothyronine) is high post thyroid lobectomy. Please pursue this with your doctor and the the thyroid surgeon. If their answers make sense could you please let me know. ...Read more

Could rhodiola cause low TSH levels?

Could rhodiola cause low TSH levels?

Unlikely but...: Rhodiola is known to improve thyroid function and thus might be expected to reduce TSH levels somewhat (though more research on this is needed). However, a low TSH tends to be a sign of hyperthyroidism and, as far as i know, rhodiola is not known to stimulate the thyroid to the point of hyperthyroidism. ...Read more

Do low T3 (liothyronine) and free T3 (liothyronine) values mean hypothyroidism?

Do low T3 (liothyronine) and free T3 (liothyronine) values mean hypothyroidism?

Possibly.: These along with low t4, free t4, and high TSH would mean hypothyroidism. But a low TSH would possibly mean a hypothalamus/pituitary problem. If any of the thyroid values/tsh are not low, then it might be wise to keep following before having a diagnosis made and therapy done. Check with your doctor to be sure. ...Read more

Low TSH Borderline low T4 normal t3 (liothyronine). Thyroid uptake scan..low uptake noted w\o nodules. Radiologist said HYPOTHYROIDISM?! All other possible test norm

Need follow-up: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, there is inconsistency in your results. Both TSH and T4 being low does not add up. You may need to repeat the lab tests, not necessarily the scan, in about 6 months to see what direction these results are going in. ...Read more

Do I need thyroid hormone if I have low free t3, (liothyronine) normal TSH and high tpo antibodies?

Do I need thyroid hormone if I have low free t3, (liothyronine) normal TSH and high tpo antibodies?

Possibly.: The TSH is normal so it might be a variation of normal or euthyroid. It also might be a developing thyroid condition, but there would be symptoms, like fatigue. The tpo antibodies might mean hashimoto's thyroiditis. This is usually associated with hypothyroidism. It would be wise to see your doctor to follow up. ...Read more

Synthroid (thyroxine) or Armour Thyroid for hypothyriodism?

Synthroid (thyroxine) or Armour Thyroid for  hypothyriodism?

Levothyroxine.: Levothyroxine, generic form of synthroid, has many advantages over armour thyroid. The armour product has significant batch to batch variation and has T3 (liothyronine) in it. Since the T3 (liothyronine) portion of armour has a very quick onset and short duration, it can wreak havoc with the ability to effectively treat hypothyroidism. Until there is a long-acting form of T3 (liothyronine) available, stick to levothyroxine. ...Read more
