What is mean by ultra TSH?
TSH itself is produced by the pituitary gland when TRH (Thyrotropin releasing hormone) stimulates it. The Hypothalamus is responsible for producing TRH. TSH then stimulates the Thyroid Gland to produce T3 and T4. TSH Ultrasensitive is important to: Diagnose Hyperthyroidism & Hypothyroidism.
What is considered a high TSH level?
The standard reference range for the TSH level is anywhere between 0.30 and 5.0 uIU/mL. If your TSH level is higher than 5.0 uIU/mL, then the lab will flag you as “high,” and you may experience the symptoms listed above 5.0 uIU/mL. Values of the TSH level more than 10.0 uIU/mL need long-term thyroid supplements.
What is an abnormal TSH level?
A normal range for TSH in most laboratories is 0.4 milliunits per liter (mU/L) to 4.0 mU/L. If your TSH is higher than 4.0 mU/L on repeat tests, you probably have hypothyroidism. Your doctor may also order a T4 test.
Is TSH 7.0 high?
According to Cappola, her research regarded mildly elevated TSH levels as those in the 4.5 to 7 mU/L range, while very elevated TSH levels were considered to be those greater than 20 mU/L.
What are the causes of increased TSH levels?
Hypothyroidism is one of the most common causes of elevated TSH levels, the National Institute of Diabetes and Digestive and Kidney Disorders explains. The pituitary makes TSH to stimulate the production of thyroid hormones.
What are the normal levels of TSH?
The typical range of reference for TSH levels is anywhere between 0.4 and 4.9 milliunits per liter (mU/L). A recent study suggests that the normal range should be more like 0.45 to 4.12 mU/L. TSH can vary wildly based on your age, sex, and stage of life.
What are the dangers of low TSH levels?
Serious complications can result from low TSH levels.These complications can include a variety of heart problems, weak bones, eye and skin problems, and thyrotoxic crisis—a serious condition that can cause delirious behavior. Seek medical care if your symptoms increase intensely as this can indicate thyroxic crisis.
How high can TSH levels get?
High Levels of TSH. TSH levels typically fall between 0.4 and 4.0 milliunits per liter (mU/L), according to the American Thyroid Association . Ranges between laboratories will vary with the upper limit being between 4 to 5. If your level is higher than this, chances are you have an underactive thyroid.
