Do benzodiazepines have any affect on tsh, t3, (liothyronine) t4, free t3, (liothyronine) free t4, or reverse T3 (liothyronine) levels? Will they affect my thyroid test results?

No they won't. By the way, many of your thyroid tests are worthless and unnecesssary. The only ones needed are free T4 and tsh. The others aren't needed and can lead some doctors into making incorrect decisions about the thyroid. Read more...
Sometimes. Benzos do not change basal secretion of TSH, but they do decrease the amount of TSH released by exposure to cold. In one study, diazepam reduced affinity of nuclear T3 (liothyronine) binding. So benzos can have some theoretical effects, but it should not be enough to affect standard thyroid tests. Read more...

How can I get my dr to properly test me for thyroid disorders? He only tested my TSH and t4. Refused to test free T3 (liothyronine) or free t4, or anything else.

No need for more. Tests. If your TSH and T4 are normal, you do not need more tests for thyroid function. Do you have any symptoms that make you feel that your thyroid function is abnormal? However, if you are not satisfied, you could see an endocrinologist or a different endocrinologist. Read more...
Thyroid disorders. If your TSH was normal, then it is extremely unlikely that there is anything wrong with your thyroid. The TSH represents your pituitary's "opinion" of your thyroid status, and that is more reliable than anything else. What makes you think you have a thyroid disorder? The symptoms of thyroid disorders are common symptoms of many other things. Read more...
Proper? Why do you think your physician didn't do "proper" testing? Just because more tests exist, doesn't mean they are needed or useful. Read more...

Doc ordered a free T4 and a tsh-3rd generation. Dont I also need a free t3 (liothyronine)?

Not usually. For screening purposes, a TSH level by itself leads to the correct diagnosis ~ 98% of the time. Free T4 can increase this to nearly 100%. Free T3 (liothyronine) is usually not needed unless there is a discrepancy between the other labs and a person's symptoms. Free T3 (liothyronine) is useful in following patients with known hyperthyroidism, and patients taking a combination of T4 & T3 (liothyronine) thyroid hormone. Read more...

My TSH is 0.01 whereas my free T3 (liothyronine) and free T4 are normal. I feel horrible, but my doc says I am ok. Next steps?

Depends. Hi. You most likely: 1) are in a phase of a subacute thyroiditis, or 2) have one or more autonomously hyperfunctioning thyroid nodules. Those two can be distinguished by following your TSH, free T4, and Free T3 (liothyronine) over time, or by doing a nuclear medicine thyroid uptakes and scan. You can feel crummy from either condition. Subacute thyroiditis usually resolves on its own; hyper nodules need treatment. Read more...

Thyroid was checked can you tell me if this looks ok. My TSH 0.46 Free T3 (liothyronine) 4.9 Free T4 17.9?

Thyroid tests. Although I am not as familiar with the "normal range" in the UK (versus US), these numbers all look to be normal. However, you need to pose this question to the doctor who ordered them, since it is not clear why they were measured in the first place. Read more...
