A TSH, or thyrotropin, test is a blood test that looks at levels of thyroid-stimulating hormones in the blood. Doctors use the results to see how effectively a person’s thyroid is functioning.
The thyroid is a small butterfly-shaped gland located in the neck, in front of the windpipe. Its
These hormones help regulate the body’s metabolism, which is how it provides energy from food a person consumes. It can also help regulate:
- body weight
- body temperature
- heart rate
- mood
TSH can vary throughout:
- life, depending on a person’s age, sex, and weight
- pregnancy
- a
24-hour period
Different laboratories may use slightly different average TSH levels. Laboratories will look at a range of TSH levels in the healthy adult population to decide what is optimal.
In general, however, optimal TSH level ranges for healthy adults are 0.4–4.0 milliunits per liter (mU/I).
High TSH levels may suggest a person has an underactive thyroid, or hypothyroidism. By contrast, low TSH levels may indicate a person has an overactive thyroid, or hyperthyroidism.
People should discuss their test results with a healthcare professional.
Individuals who are experiencing symptoms of hypothyroidism or hyperthyroidism may benefit from a TSH test.
Hypothyroidism
According to the American Thyroid Association, there are no specific symptoms of hypothyroidism. Many underactive thyroid symptoms can occur in people with other health conditions.
The length of time a person experiences symptoms may indicate whether they have this condition. The longer they have had the symptoms, the less likely they are to have hypothyroidism.
People with an underactive thyroid may experience the following:
- fatigue
- sensitivity to cold temperatures
- unexplained weight gain
- constipation
- depression
- muscle cramps, pain, and weakness
- dry and scaly skin and brittle hair and nails
- loss of sex drive
- pain, numbness, or tingling in the hands and fingers
- heavy or irregular periods

Hyperthyroidism
Hyperthyroidism has clearer symptoms than hypothyroidism, although some may have associations with other health conditions.
People with an overactive thyroid may experience the following:
- nervousness and irritability
- bulging eyes
- increased sweating and sensitivity to heat
- swelling in the neck
- fast heartbeat
- anxiety and difficulty sleeping
- thinning of the skin
- brittle hair
- muscle weakness
- frequent bowel movements and diarrhea
- unexplained weight loss
- lighter or irregular periods
Graves’ disease is the most common condition that experts associate with an overactive thyroid gland. About 3 in 4 people with an overactive thyroid have the condition.
Graves’ disease is more common in young or middle-aged females and in people who smoke.

However, some people may have high thyroid hormone levels if they are pregnant or taking birth control pills. Also, T4 levels may be lower in those who take medications for asthma, arthritis, or some skin conditions.
- T3 test: Measuring T3 levels can help doctors reach a final diagnosis if a person’s T4 levels are within a healthy range but they believe the person has high thyroid hormone levels.
- Thyroid antibody test: Doctors may perform a thyroid antibody test to check whether a person has an autoimmune thyroid disorder, such as Graves’ disease or Hashimoto’s disease.
