We have case , femal patien , age 60 years, the TSH less than 0.05 while T4 in normal range , and she has not any symptom of thyroidism , is it ok ?

Subclinical hyperthy: A low TSH with a normal T4 and no symptoms is usually subclinical hyperthyroidism. She may have a multinodular goiter that is autonomously functioning, or very early graves disease. A T3 (liothyronine) level and free T4 level should be checked. There is a higher risk of developing atrial fibrillation despite the normal T4 level, but many endocrinologists would just follow her levels for progression. ...Read more

Could an elevation in one's TSH level be indicative of hyper/hypo thyroidism?

Could an elevation in one's TSH level be indicative of hyper/hypo thyroidism?

Hypothyroidism: When the thyroid makes too little hormone (t4 and t3), the pituitary makes more TSH to try to compensate. So an elevated TSH is indicative of a thyroid that has failed or is failing, and you may need to take levothyroxine. See your doctor. ...Read more

I'm not sure what: ..units are being used to measure your TSH level, but 100??? In the USA, the standard value that labs use to measure TSH is microunits/ml and normal values range from 0.4 to 4.0 microunits/ml. If you're TSH is 100 mcu/ml, then definitely something's wrong with your thyroid or the hormones regulating it. This test result requires follow up and either clarification or treatment. ...Read more

If my tsh low, t3 (liothyronine) and t4 is normal, is it hypo or hyper thyroidism? Should I take iodine? Ultra sound is normal, without pathology.

Hypothyroid: The answer to this question depends on what your exact levels are and what type of symptoms you have. "Subclinical Hypothyroidsim" sometimes presents in the manner you describe. ...Read more

Which test is best to monitor thyroid levels in thyroidectomy patients, just ft3 and ft4, TSH and ft4, or like i feel should be tsh, ft3 and ft4?

TSH: All you really need is a tsh. Assuming there is nothing wrong with your pituitary, this hormone responds in a very sensitive manner to the levels of your T4 and t3 (liothyronine). You are presumably taking levothyroxine as replacement. ...Read more

Is TSH the best test to find out if your having thyroid problems? Mine tested 2.0 and 1.78 but my neck always feels "thick" along with other hypo symp

Is TSH the best test to find out if your having thyroid problems? Mine tested 2.0 and 1.78 but my neck always feels "thick" along with other hypo symp

Thyroid function: Hypothyroid symptoms are often not-specific and can overlap with symptoms from other disorders. Tsh elevation is normally seen in patients with an underactive thyroid who have goiter. Normal TSH can be seen in patients with pituitary dysfunction leading to hypothryoidism, but goiter not part of that. Neck thickness likely due to something else if TSH is ok. Please discuss symptoms with your doc. ...Read more

Symptoms of both hyper and hypo thyroid for some time now. Tsh has risen from 0.6 to 2.1 in 2yrs. Free T4 is 12. Normal to increase? Follow up tests?

Symptoms of both hyper and hypo thyroid for some time now. Tsh has risen from 0.6 to 2.1 in 2yrs. Free T4 is 12. Normal to increase? Follow up tests?

Abnormal thyroid tes: The lab values that you have submitted appear to be an error. The TSH test appear to be in normal range but the free T4 appears to be 10 times the normal value. Are you sure this is not the total T4? In that case your labs are normal and a total T4 elevation would indicate use of birth control pills, which can raise total T4. I would repeat these tests first and if confirmed, look in the pituitary ...Read more
