Is there synthetic tsh?

Is there synthetic tsh?

No: Tsh is produced in the anterior pituitary gland in the brain. Its function is to regulate thyroid hormone production in the thyroid gland itself. The TSH test is just to monitor that feedback loop. If there is too little thyroid hormone, then that is given exogenously because that has a physiologic function. Tsh does not. If the pituitary is treated if it's abnormally producing extra tsh. ...Read more

I have TSH at 7.78. I am 46?

Tsh .55,t-3 88, t-4 10 Is this optimal?

Tsh .55,t-3 88,  t-4 10 Is this optimal?

No problem: Hi. Those thyroid function tests are normal. However, a total T4 has only a fraction of the value of a free T4, so you might want to suggest to your old-timer doc to stop ordering total T4 and get a free T4. But it wouldn't change anything. You're toward the hyper end of normal, and that's OK. Are you taking l-thyroxine? Good luck! ...Read more
