Yes, it is possible to have a high TSH result while simultaneously having hypERthyroidism. The tests for hyperthyroidism must be used together to give an appropriate impression of thyroid function and diagnosis of dysfunction. The TSH test only tests the hormone called Thyroid Stimulating Hormone, which is produced in the brain and turns the thyroid on. To test for hyperthyroidism, your doctor will need to test Free T3 and Free T4. These are the hormones produced by the thyroid.
If the pituitary gland in the brain is overproducing TSH (often due to a tumor) while the patient has concurrent thyroid disease such as Graves' Disease; overconsumption of iodine; thyroid tumor or other cause of hyperthyroidism; the patient will have an elevated TSH along with elevated Free T3, and Free T4 levels.
Because TSH is a part of the body's negative feedback system which controls the thyroid's output of thyroid hormones, a DECREASE of TSH would indicate hypERthyroidism. An INCREASE of TSH indicates hypOthyroidism.
No. An overproduction of TSH would cause hyperthyroidism.
TSH is not a thyroid hormone - it is a pituitary hormone called Thyroid Stimulating Hormone. It's job is to tell the thyroid how much thyroid hormone to produce. This is called a negative feedback system.The thyroid produces hormone.The brain reads that there is insufficient hormone in the bodyThe pituitary gland in the brain produces more TSH that turns the thyroid onMore TSH means the thyroid produces even more thyroid hormone.When there is too much thyroid hormone in the body, the pituitary turns off TSH as the body doesn't need any MORE thyroid hormone.If the brain, pituitary and thyroid are working properly, thyroid hormones T4 and T3 will be high (hypERthyroidism) when TSH is low, and thyroid hormones T4 and T3 will be low (hypOthyroidism) when TSH is high.
TSH is thyroid stimulating hormone. It is produced by the pituitary to turn on the thyroid gland. If TSH is low, that is because there is sufficient (or too much ) thyroid hormone in the body, so the pituitary needs less to keep the thyroid functioning. Thyroid hormones measured in lab tests are usually FreeT4 and FreeT3.
A thyroid stimulating hormone (TSH) test is an initial test used to determine how your thyroid is functioning. A high TSH level indicates that the thyroid gland isn't making enough hormones, causing hypothyroidism. Conversely, if the TSH level is low it indicates an overactive thyroid, known as hyperthyroidism. The TSH normal level range that most physicians refer to is .3 to 4.5.
Hyperactive thyroid is also known as hyperthyroidism. This is where the thyroid produces too much thyroid stimulating hormone (TSH), which causes ADHD related symptoms and a racy metabolism. If left untreated with a TSH blood test or otherwise, it will lead to some health issues, most notably heart and bone issues.
is a 3.89 tsh level high?
Hyperthyroidism would be a condition in which T3 and T4 are at increased levels.

high TSH than the normal range means hypothyrodism.
hypothyroidism
Yes, absolutely! Even when using the older measurements TSH 0.3 - 5.0, that is exceptionally high
