Normal levels of TSH vary based on your age. In general, if you're healthy and not pregnant, the normal ranges of TSH include: Infants up to 5 days old: 0.7 – 15.2 micro-international units per milliliter (uIU/mL). Infants 6 to 90 days old: 0.72 – 11.0 …

2020年1月8日 · The typical range of reference for TSH levels is anywhere between 0.45 and 4.5 milliunits per liter (mU/L). A recent study suggests that the normal range should be more like 0.45 to 4.12 mU/L.

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.

2023年12月22日 · Normal TSH levels, in both females and males, range from 0.4 to 4.0 milliunits per liter (mU/L). What is a good TSH level for age? TSH levels rise abruptly to 60–80 mU/L within 30–60...

2024年8月17日 · The normal range for TSH is between 0.4 and 4.0 milli-international units per milliliter (mUI/mL), although this can vary slightly depending on the laboratory's reference range for that test.

2023年11月14日 · Doctors have figured out normal TSH levels by age. The ranges are as follows: TSH and pregnancy. Being pregnant can affect your TSH levels. In general, the TSH levels during different trimesters...

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.

TSH normal values are 0.5 to 5.0 mIU/L. Pregnancy, a history of thyroid cancer, history of pituitary gland disease, and older age are some situations when TSH is optimally maintained in a different range as guided by an endocrinologist.

2023年3月22日 · The normal range of TSH levels in adults is between 0.4 to 4.0 mIU/L (milli-international units per liter). Some research suggests that this range should actually be more like 0.45 to 2.5...
