2023年12月22日 · The thyroid-stimulating hormone (TSH) test measures the amount of TSH in the blood to convey how well a person’s thyroid functions. Normal levels are typically 0.4 to 4.0 milliunits per liter...

2022年3月24日 · The normal range for thyroid-stimulating hormone (TSH) is 0.35 to 4.5 milli-international units per liter (mIU/l) of blood. TSH is a hormone produced by your pituitary gland that regulates the production of hormones by your thyroid gland. The levels of TSH in your body can tell you how well your thyroid gland is functioning.

2025年3月21日 · Normal thyroid-stimulating hormone (TSH) levels generally fall between 0.5 and 5.0 milliunits per liter (mU/L). If your TSH level is higher than 5.0 mU/L it suggests an underactive thyroid, or hypothyroidism, since TSH regulates hormone production.

2018年5月7日 · Find out all you need to know about TSH levels (including normal, high or low thyroid stimulating hormone levels). Read what doctors say about optimal TSH levels and how they affect thyroid hormones T4 and T3. Including useful chart of TSH, FT4, FT3 levels.

2022年11月28日 · 促甲状腺激素，即TSH指标，是腺垂体分泌的促进甲状腺的生长和机能的激素。 正常范围：2-10mU/L。 促甲状腺激素具有促进甲状腺滤泡上皮细胞增生、甲状腺激素合成和释放的作用。 促甲状腺激素和甲状腺激素不是一回事，但却有着重要的联系。 甲状腺激素是甲状腺分泌的，促甲状腺激素是垂体分泌的，而促甲状腺激素作用于甲状腺，令其分泌甲状腺激素。 促甲状腺激素是甲状腺健康与否的一个重要指标，一旦它偏高或偏低，就代表甲状腺在这一阶段内出 …

A TSH blood test is usually the first test providers order if you’re experiencing symptoms related to thyroid issues. What happens when TSH levels are too low? If you have too little TSH, it’s most likely that your thyroid gland is making excess thyroid hormone. This condition is called hyperthyroidism, or overactive thyroid.

A high TSH level indicates that the thyroid gland is not making enough thyroid hormone (primary hypothyroidism). On the other hand, a low TSH level usually indicates that the thyroid is producing too much thyroid hormone (hyperthyroidism). Occasionally, a low TSH may result from an abnormality in the pituitary gland, which prevents it from ...

2025年3月20日 · 当TSH水平偏高时，通常说明甲状腺受到的刺激不够，可能分泌不足，这种情况我们称之为亚临床甲减（甲状腺功能减退症的早期阶段）或者是甲减。

2007年12月1日 · With TSH screening and physician awareness of thyroid disorders, a large number of individuals, up to 10% of the tested population, will have serum TSH values above the level of 4.5 mIU/liter (14). A lowering of the upper limit of normal for TSH may result in a tripling of the frequency of abnormal results for persons over 50 yr old (15).

2021年1月20日 · Normal TSH levels are around 0.4-4.5 mIU/ml. If your TSH levels are high, you may have an underactive thyroid. On the other hand, low TSH levels can signal an overactive thyroid. TSH levels also normally increase with age and studies suggest that slightly higher TSH levels may be beneficial in older people.
