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.

Does the over production of tsh cause hypothyroidism?
No. An overproduction of TSH would cause hyperthyroidism.
Could you have high tsh but still have hyperthyroidism?
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.
What is thyroid hyperthyroidism?
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.
Would a patient with a TSH level of 3.68 be considered to have hypothyroidism or hyperthyroidism?
A TSH of 3.68 is within the normal range. However, doctors like to see a TSH between .3 and 3 in those patients receiving thyroid replacement medications. Additionally, normal for one person may not be normal for another. Just as I wear a different shoe size than my husband, everyone's systems require different levels for them to feel well. My husband's shoe size is normal, so is mine. I will not be comfortable wearing his shoes all day however. A TSH test only shows an average value of your thyroid status over the last several weeks. You may still be experiencing periods of high and/or low thyroid and your TSH will appear normal. Knowing the level of your Free T3 and Free T4 as well as antibody levels will help determine what is going on and if you need treatment. When a TSH appears high, a patient is considered hypOthyroid. When a TSH is low, a patient is considered hypERthyroid.
What condition results in low TSH levels and increased T3 and T4 levels?
Hyperthyroidism would be a condition in which T3 and T4 are at increased levels.
Why low TSH is called hyperthyroidism and high TSH is called hypo thyroidism?
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.
What does a tsh test of 2.8 mean?
It means that the level of thyroid stimulating hormone (TSH) in your blood stream is lower than it should be. Ideally it should be between 0.35 and 5 U/L. A TSH of this level can be caused by a number of different things. 1. Taking too much thyroxine or triiodothyronine to treat hypothyroidism 2. Hyperthyroidism 3. Secondary Hypothyroidism: this is where both the levels of TSH and free T4 are low
Is a TSH of 2.2 considered normal?
yes
Why low TSH is called hyperthyroidism and high Tsh is called hypo thyoridism?
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.
What does medical code 84443 stand for?
CPT code 84443 refert to Thyroid stimulating hormone (TSH).The TSH test is performed to determine the thyroid function, identify any type of thyroid disorder, and detect any symptoms like hypo– or hyperthyroidism. For newborns, this is performed to detect an underactive thyroid. A blood sample is collected from a vein in the arm (in adults) or from the heel (in newborn) and tested for TSH by various immunoassay techniques. A high TSH result usually means an underactive thyroid gland not responding properly to the stimulation of TSH due to some thyroid disorder. A low TSH result generally indicates an overactive thyroid gland (hyperthyroidism).With an antiseptic, the physician or the healthcare provider cleans the skin where blood is to be drawn. Blood is usually taken from a vein at the arm or the back of the hand. An elastic band is wrapped tightly around the upper arm so that the vein at the arm swells suitably. Next, a needle is inserted into the vein and around 5 ml of blood is drawn out into a collection tube. The needle is removed and the puncture site is closed properly. In newborns, the blood is drawn from the heel by pricking it with a lancet. The collected blood specimen is then examined using procedures like radioimmunoassay (RIA), enzyme immunoassay with monoclonal antibodies, etc. A high value of TSH indicates hypothyroidism or an underactive thyroid, whereas a low TSH result indicates hyperthyroidism or over–activity of thyroid.The TSH test measures the amount of thyroid stimulating hormone (TSH) produced by the pituitary gland. TSH controls the production of T3 and T4 hormone by the thyroid gland. The normal value of TSH in blood is 0.4 – 4.0 mlU/L.
What is the meaning of laboratory test?
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.
What is the thyroid hormone dosage for person with 7.8 TSH level?
what medicine require to take in 7.8 tsh value
