Low TSH: Third generation TSH testing is the most accurate test available for detecting thyroid function abnormalities. A low TSH indicates thyroid hyperfunction, or over activity. There is always the potential of a lab error, but barring that, the test itself is very accurate. Thanks for trusting HealthTap! ...Read more

What do these types of test means:  tsh, t3, (liothyronine) t4?

Gas pedal & gas: Tsh is like the gas pedal. T3 (liothyronine) and T4 are the gas. The pituitary sends TSH [thyroid stimulating hormone], a chemical message to the thyroid to work faster or slower. High TSH means low thyroid. Low TSH means high thyroid. T3 (liothyronine) is active form of thyroid hormone. T4 is inactive thyroid hormone. ...Read more

Can someone explain my test results? TSH 3.72 T3 1.22 T4 0.83 TPO ab >900 Should I be concerned?

Thyroid tests: The TSH (thyroid simulating hormone) is the most important test of your thyroid function. It's the pituitary/brain signal to your thyroid to make more thyroid hormones t3 (liothyronine) (tri-iodothyronine) and T4 (thyroxine). Elevated TSH means low thyroid function. Unmeasurable/very low TSH means too active thyroid. T3 (liothyronine) is short acting. T4 (thyroxine) is longer lived, usually given for thyroid replacement. ...Read more

Thyroid tests: These tests appear to be in the normal range, but you have not provided the normal range. Hypothyroidism can cause weakness, but these tests suggest that you are not hypothyroid. Perhaps see your doctor to determine other causes. ...Read more

Taking thyroid med?: Hi. Those thyroid function tests are normal. If you're not taking thyroid hormone, then you're not hypothyroid. I'm sorry for the confusion; no one should have told you you're hypothyroid based on those labs. I would advise against taking desiccated porcine thyroid (Armour). See an endocrinologist if you want expert opinion on thyroid issues; many excellent ones in your area. Your thyroid's normal ...Read more

Not online: On health tap we are not really allowed to make diagnoses: this is for your protection, mainly. I will say that most endocrinologists nowadays would consider a TSH of over about 3.0 to be elevated, and so you might be hypothyroid. Ask the doctor who tested you, or consider checking with a endocrinologist or an re. ...Read more
