Understanding Your Hypothyroidism Test Results It makes thyroid-stimulating hormone, or TSH, which tells the thyroid gland how much T4 and T3 to produce. The TSH level in your blood reveals how much T4 your pituitary gland is asking your thyroid gland to make. If your TSH levels are abnormally high, it could mean you have an underactive thyroid, or hypothyroidism.“TSH levels go in the opposite direction of your thyroid hormone,” Dr. Doria-Medina explains.he TSH level in your blood reveals how much T4 your pituitary gland is asking your thyroid gland to make.

Low Thyroid Stimulating Hormone (TSH) What does a Low TSH Mean? Your thyroid gland is producing too much of the thyroid hormone which signals to your brain to stop producing anymore. Individuals who suffer from low TSH levels and high levels of T3 and T4 (the thyroid hormones) have a condition that is commonly referred to as hyperthyroidism.

TSH Levels â What Your TSH Levels Mean in a Nutshell This drop in TSH is the pituitary gland’s attempt to return circulating T3 & T4 hormone levels to normal. Therefore, the TSH test results will show lower than normal TSH when the thyroid is overactive. So, in general, lower TSH levels equals an overactive thyroid; or hyperthyroidism.

Overactive Thyroid Gland Hyperthyroidism Hyperthyroidism means an overactive thyroid gland. When your thyroid gland is overactive it makes too much thyroxine. The extra thyroxine causes many of your body's functions to speed up. In contrast, if you have hypothyroidism, you make too little thyroxine; this causes many of the body's functions to slow down.

Is Your Thyroid Doctor Using the Old TSH Lab Standards? Therefore a high TSH level suggests an underactive thyroid (hypothyroidism), while a low TSH indicates too much thyroid hormone in the body (hyperthyroidism). In my post “Miscarriage in New York City…Be Thyroid Aware”, I outlined the TSH ranges for pregnancy and provided trimester-specific ranges.

- An abnormally high TSH means hypothyroidism: the thyroid gland is being asked to make more T4 because there isn’t enough T4 in the blood. T4 tests. Most of the T4 in the blood is attached to a protein called thyroxine-binding globulin. The “bound” T4 can’t get into body cells. Only about 1%–2% of T4 in the blood is unattached (“free”) and can get into cells.

Thyroid-stimulating hormone Thyroid-stimulating hormone (also known as thyrotropin, TSH, or hTSH for human TSH) is a pituitary hormone that stimulates the thyroid gland to produce thyroxine (T 4), and then triiodothyronine (T 3) which stimulates the metabolism of almost every tissue in the body.levated reverse T 3 (RT 3) together with low-normal TSH and low-normal T 3, T 4 values, which is regarded as indicative for euthyroid sick syndrome, may also have to be investigated for chronic subacute thyroiditis (SAT) with output of subpotent hormones.

- A: Elevated thyroid-stimulating hormone levels, a condition that leads to hyperthyroidism, are associated with symptoms such as light sensitivity, visual disturbances, increased heart rate, anxiety and weight loss, according to Lab Tests Online.

What Is TSH (Thyroid-Stimulating Hormone)? TSH tells your thyroid gland how to produce other hormones. TSH, or thyroid-stimulating hormone, is produced by the pituitary gland (a pea-sized structure at the base of the brain). It helps the thyroid gland — located at the base of the neck — produce the hormones thyroxine (T4) and triiodothyronine (T3), which affect your metabolism and other bodily functions.

What Causes TSH Level High? What does a high TSH mean? TSH or thyroid stimulating hormone is a hormone produced in the anterior pituitary gland. This is used to help stimulate the thyroid to produce triiodothyronine (T3) or thyroxine (T4), hormones that help stimulate the metabolism.

High and Low TSH Levels: What They Mean So, when you've gone for a checkup, and your TSH comes in below normal (and your doctor does not have you on a suppressive dose of thyroid hormone), they may want to REDUCE your dosage of thyroid hormone, because levels below normal are considered potentially hyperthyroid (overactive.)

Summit Medical Group Web Site Thyroid-Stimulating Hormone (TSH) Test. This blood test measures how well your thyroid gland is working. This gland, which is located at the lower front of the neck, may be underactive or overactive. The test measures your body's response to the thyroid hormone level in your blood. Your body’s pituitary gland controls the activity of your thyroid gland by producing thyroid-stimulating hormone (TSH). A high TSH level means that your thyroid gland is underactive.

TSH Levels â What Your TSH Levels Mean in a Nutshell And the reverse is true as well. If your pituitary gland is constantly bombarding your thyroid with high TSH levels, it kicks the thyroid into overdrive, and your thyroid starts producing too much T3 & T4 hormones. This is what causes the condition known as “hyperthyroidism”.

Useful For Interpretation Provides information to assist in interpretation of the test results. In primary hypothyroidism, thyroid-stimulating hormone (TSH) levels will be elevated. In primary hyperthyroidism, TSH levels will be low. The ability to quantitate circulating levels of TSH is important in evaluating thyroid function.

Alternative names for thyroid stimulating hormone Thyroid stimulating hormone is produced by the pituitary gland. Its role is to regulate the production of hormones by the thyroid gland. Alternative names for thyroid stimulating hormone TSH; thyrotropin, thyrotrophin.hese hormones have a negative effect on the pituitary gland and stop the production of thyroid stimulating hormone if the levels of thyroxine and triiodothyronine are too high. They also switch off production of a hormone called thyrotropin-releasing hormone.
