Understanding Your Hypothyroidism Test Results If you’re making too much thyroid hormone, your TSH will go down.”. What’s normal can vary, depending on a number of factors, including the laboratory where your blood test is done, she adds. 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. Most of the T4 in your blood attaches to a protein, and when it does, it can’t get into your cells.

- TSH Range. The function of thyroid stimulating hormone (or TSH) is to regulate the normal levels of thyroid hormones in the body. It is a peptide hormone secreted by the thyrotrope cells of anterior pituitary gland. The TSH activates the thyroid gland to produce both Triiodothyronine(T3) and thyroxine (T4) hormones. A TSH level count ranging between 0.5 and 3mIU/L confirms thyroid disorder. 2  The normal TSH range for newborns ranges from between 1 – 39 mIU/L. 3  The normal TSH levels for children ranges from between 0.7 – 6.4 mIU/L.

- Normal TSH Values. The normal range of TSH test report can range from between 0.4 – 4.0 milli-international units per liter. The TSH value depends on various factors like lab reports, related symptoms and treatment for the condition.he official normal range of TSH followed by many doctors and laboratories until 2002 was from between 0.5 to 5. According to this TSH range, a TSH over 5 indicated an under active thyroid (or hypothyroidism); while a low TSH value below0.5 indicated an overactive thyroid or (hyperthyroidism).

Normal Thyroid Levels - What is a Normal Thyroid Range Normal TSH Level. The normal thyroid level for TSH for labs in UK is 0.5 to 5.5 mIU/L (milli-international units per liter). Labs in the U.S. followed the same reference scale until 2003. In spring 2003, the scale was revised to new standards, which specified 0.3 to 3.3 mIU/L as normal TSH level.he under activity of these hormones results in hypothyroidism while hyperthyroidism, is an outcome of over-activity of T3 and T4 hormones. The levels of T3 and T4 in the body are determined by another hormone called Thyroid Stimulating Hormone (TSH). This hormone is secreted by the pituitary gland.

- As you know from this article a normal TSH range depending on the lab is around 0.5 to 5.0 which is why your TSH of 4.46 was determined normal, however the very fact that your first TSH test showed up 6.49 should be reason to investigate further.i Diane, I assume the blood test value of 0.03 refers to TSH. Normally the reference range for TSH is around 0.5 to 5.0 but thyroid doctors have been debating these numbers for years. 0.03 is lower than “normal” however TSH does not give a full picture.

TSH Range Normal and Abnormal Test Results. Although various professional health bodies have specified the normal range for TSH to be 0.4 - 4.5 mIU/L in the past, new regulations recognize that this range is too wide. Currently, the standard reference range for TSH is 0.4 - 3.0 mIU/L. However, clinical data show that 95% of euthyroid patients fall in the range 0.4 - 2.5 mIU/L. In addition, adults with TSH levels over 2.0 mIU/L are likely to develop hypothyroidism later in life. Therefore, the ideal range of TSH is 0.4 - 2.0 mIU/L. Children, generally, have higher TSH levels than adult. The National Academy of Clinical Biochemistry recommends 1.3 - 19 mUI/L for newborns. These values drop with age and by the first year, TSH level for an infant should be between 0.4 mIU/L and 7 mIU/L.

Thyroid Hormone Testing: Whatâs the Best TSH Level? Clinical chemists and doctors decided decades ago that healthy people with normal functioning thyroid glands have TSH levels within a range of 0.450 to 4.500 mIU/L (and some labs go as high as 5.000mIU/L). In clinical shorthand, the diagnostic range is rounded out to 0.4-4.0.

Understanding the TSH Test and Its Controversies As of late 2016, at most laboratories in the U.S., the official reference range for the Thyroid Stimulating Hormone (TSH) blood test runs from approximately 0.5 to 4.5/5.0. The reference range -- also sometimes called the normal range -- is an important part of the complete picture of thyroid diagnosis and treatment. In fact,the entire TSH test as diagnostic and management tool depends on this validity.
