If you’re looking at your TSH test results, you need to find a TSH levels chart which indicates the normal range. Thyroid stimulating hormone (TSH) levels are measured in this thyroid test to diagnose your thyroid hormone levels. High and low TSH levels could be symptoms of an underlying condition. Find out the normal TSH levels for you!
TSH Levels Chart for Normal Thyroid Stimulating Hormones
Thyroid Stimulating Hormones
TSH are hormones released by the body to stimulate the thyroid gland and produce thyroid hormones. If you’re too low on the thyroid levels chart, the TSH increases, and if your thyroid levels are too high, your TSH levels may be low. Abnormal TSH levels can be caused by bodily changes and medication or supplements but most of the time, it’s an indicator of an underlying thyroid condition. TSH levels are measured by milli-international units per liter or mlU/L.
Normal TSH levels for adults range from 0.4-9 mlU/L but there is also a difference in levels depending on age. For adults between age 21 and 54, the normal TSH levels are 0.4-4.2 mlU/L. While 55-87 years-old have higher levels ranging from 0.5-8.9 mlU/L.
For Pregnant Women
There is also a variation in normal TSH levels for women during pregnancy. Throughout the first and second trimester, the normal ranges are 0.3-4.6 mlU/L. During the third trimester, TSH levels are within the normal range from 0.8 all the way to 5.2 mlU/L.
Children have their own normal TSH levels as well and each age group has their own varying normal levels. Newborn babies, until they’re four days old, have normal TSH levels at 1-39 mlU/L. Once they’re 2-20 weeks old, it increases to 1.7-9.1 mlU/L. From the 20-week mark until they’re 20 years old, the normal levels are 0.7-64 mlU/L.
For Premature Babies
There is also a TSH levels chart for premature babies because their mothers’ thyroid condition could lead to neonatal thyroid conditions. Today, there is a growing number of parents who consult their doctors for TSH tests for their premature babies. These babies are usually 28-36 weeks old and their normal TSH levels range from 0.7-27 mlU/L. It is impossible to tell which infant is likely to be affected by Congenital hypothyroidism or other thyroid disorder. That’s why, newborn screening programs were generated to identify and treat this disorder as early as possible, by measuring either thyroxine (T4) and thyrotropin (thyroid-stimulating hormone [TSH]) in heel stick blood specimens.

Normal TSH levels are different for every age group. It’s also very different for women going through pregnancy. This TSH levels chart is a good reference to find out if your levels are normal. Still, the best and most accurate way to receive results about the health of your thyroid is by consulting your doctor about your TSH test results. Some TSH test results are not accurate and the best way to get an accurate diagnosis is by undergoing other thyroid tests. If you want to get an accurate result, you should undergo several tests to have a comparison of each result instead of just sticking to one test. It may take time and money but in time, you’ll get the result you want to see.
