What can cause high TSH level after several years of Synthroid (thyroxine) for post ablative  (graves) hypothroidism?

Usually low Thyroid : Post ablative hypothyroidism is a condition where the thyroid gland is not functioning well and thus the patient needs more thyroid hormone. A "high tsh" actually mean there is not enough thyroid in the blood, thus an increase in dosage of the synthroid (thyroxine) is needed.

What can cause a false high tsh?

Not much: Any lab can have a temporary problems doing any test accurately. That is why an abnormal level should always be repeated to verify it. There are temporary causes for high TSH (resolving subacute thyroiditis), so that a 2nd TSH level done a few weeks after an abnormal one, could be normal. Subclinical hypothyroidism will have a high TSH with other thyroid levels normal, no symptoms. ...Read more

Above 4.5: In most labs, a value above 4.5 is high. However, symptoms related to low thyroid correlate much better with free T4 levels, rather than tsh.

What is a dangerously high TSH level?

What is a dangerously high TSH level?

Hypothyroidism: The actual thyroid hormone is T4 and t3 (liothyronine). When they are low, TSH elevates, but how high is somewhat variable, and "high tsh" per se is not dangerous. A low t4/t3 (liothyronine) can be dangerous; TSH is a good marker of thyroid function, but often it is necessary to measure ft4 or t3 (liothyronine). A mild elevation of TSH (eg. 4-10) is often without any symptoms and a normal ft4. ...Read more

My last blood results showed a high TSH levels but t3andt4 in normal range. Should i see someone regarding hypotyhroidism?

Yes: An elevated TSH indicates that your pituitary gland feels that your thyroid level is somewhat low. The fact that the T4 and T3 (liothyronine) are normal means that the problem is still mild. If you have symptoms of an underactive thyroid, treatment with thyroid hormone is indicated. If you have no symptoms, and the TSH is only mildly high, one can repeat the level in a few months and see if it has changed. ...Read more

I have a high TSH but normal T4 levels, what does this mean?

I have a high TSH but normal T4 levels, what does this mean?

Hypothyroidism: The TSH test is10 times more sensitive for the diagnosis of hypothyroidism that the t4. The TSH is reported on a log scale so that small changes in the TSH value are caused by relatively big changes in the blood level. This is a reflection of the pituitary being extremely sensitive to change in the T3 (liothyronine) level if you have symptoms it would be wise to seek treatment. ...Read more
