What does TSH 4.6 mean?
What does TSH 4.6 mean?
Subclinical hypothyroidism is defined as a thyroid stimulating hormone (TSH) level of 4.6 to 10 mIU/L. A normal TSH level is 0.4 to 4.0 and full-blown hypothyroidism is 10 or higher.
What is a good reading for TSH?
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 different range as guided by an endocrinologist. FT4 normal values are 0.7 to 1.9ng/dL.
What TSH level is considered severe?
Some suggest that TSH levels of over 2.5 milliunits per liter (mU/L) are abnormal, while others consider levels of TSH to be too high only after they have reached 4 to 5 mU/L. Both children and teenagers as well as older people have somewhat higher TSH levels than middle-aged people.
What is a normal TSH level uIU mL?
Reference range for TSH is 0.35 – 5.5 uIU/mL. Reference range for free T4 is 0.8 – 1.6 ng/dL.
Is 4.8 TSH high?
Most labs say that a normal serum TSH level is somewhere between 0.4 to 4.0 mIU/L, and that a TSH level of 10 mIU/L or higher is indicative of hypothyroidism. A TSH level of 4.5 to 10 mIU/L is considered indicative of subclinical hypothyroidism.
What are the symptoms of high TSH?

- weight gain.
- swelling of the face and neck.

What happens if your TSH is too high?
TSH is a hormone that is created by the pituitary gland that tells the thyroid gland how much thyroid hormone to make. Symptoms of high TSH include fatigue, depression, cold intolerance, constipation, infertility and other symptoms.
What causes TSH levels to be high?
High TSH levels indicate hypothyroidism. People develop hypothyroidism when their thyroid produces low levels of hormones. When someone’s thyroid gland does not produce enough hormones, the pituitary gland produces more TSH to compensate. Symptoms of hypothyroidism may include: fatigue.
What happens if TSH is slightly high?
If your TSH levels are abnormally high, it could mean you have an underactive thyroid, or hypothyroidism. That’s because it indicates your pituitary gland is producing more TSH in an effort to stimulate your thyroid to produce thyroid hormone, according to the Mayo Clinic.
Does high TSH cause weight gain?
Weight gain: Unexpected weight gain, often accompanied by persistent fatigue, is among the earliest signs of hypothyroidism. High TSH levels and weight gain often go hand in hand. You might not realize that fatigue and weight gain are linked to a thyroid problem until more symptoms emerge.

What is a normal TSH level for a woman?
An optimal TSH level in a woman is 0.4-2.5 mIU/L. For pregnant women, that upper limit is stricter than if you are not pregnant. A dangerously high level of TSH is above 5.0 mIU/L. High TSH means low thyroid hormones.
What is the normal range for TSH and T4?
According to the U.S. National Library of Medicine the normal TSH range in healthy adults is 0.4 to 4.0 milli-international units per liter (0.4 – 4.0 mIU/L). 7 For your thyroid to be working correctly, your lab test results for normal free T4 levels should be 9 – 23 pmol/L (0.7 – 1.8 ng/dL)
What is T4 T3 and TSH?
Triiodothyronine (T3) and thyroxine (T4) are two thyroid hormones that TSH stimulates. Doctors say that T4 is the most important of the thyroid hormones and affects almost every function in the human body. If doctors suspect hyperthyroidism or hypothyroidism, they usually test T4 levels.
What is the TSH levels test used for?
