The normal range of TSH levels in non-pregnant adult women is 0.5 to 5.0 mIU/L. In women, during the menstruation cycle, pregnancy, or after menopause, TSH levels may fall slightly outside the normal range, because of fluctuating levels of estrogen.

Similarly, What is normal TSH level for age?

Low TSH levels usually mean that you’re producing too much thyroid hormone.

Age range Normal Low
18–30

years

0.5–4.1 mU/L

< 0.5 mU/L
31–50 years 0.5–4.1 mU/L < 0.5 mU/L
51–70 years 0.5–4.5 mU/L < 0.5 mU/L
71–90 years 0.4–5.2 mU/L < 0.4 mU/L

Additionally, What is a bad TSH level? It’s the TSH levels that are the source of all the squabble among doctors. Most doctors agree that any TSH above 10, especially when combined with an abnormal T3 or T4 reading, should be treated. Many labs, like mine, consider a TSH reading above five or so to be abnormal.

What TSH levels are considered hypothyroidism?

TSH > 4.0/mU/L with a low T4 level indicates hypothyroidism.

If your TSH is > 4.0 mU/L and your T4 level is normal, this may prompt your physician to test your serum anti-thyroid peroxidase (anti-TPO) antibodies.

What happens if TSH is high in female?

High TSH levels can mean your thyroid is not making enough thyroid hormones, a condition called hypothyroidism. Low TSH levels can mean your thyroid is making too much of the hormones, a condition called hyperthyroidism.

Is TSH 5.5 high?

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.

Is TSH 7 high?

According to Cappola, her research regarded mildly elevated TSH levels as those in the 4.5 to 7 mU/L range, while very elevated TSH levels were considered to be those greater than 20 mU/L.

What is considered an extremely high TSH level?

The standard reference range for the TSH level is anywhere between 0.30 and 5.0 uIU/mL. If your TSH level is higher than 5.0 uIU/mL, then the lab will flag you as “high,” and you may experience the symptoms listed above 5.0 uIU/mL. Values of the TSH level more than 10.0 uIU/mL need long-term thyroid supplements.

Is TSH 9 too high?

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.

Is TSH 4.4 Too high?

Generally, TSH levels higher than 4.5 mU/L indicate hypothyroidism, or an underactive thyroid, meaning your body isn’t making enough thyroid hormone. Hashimoto’s thyroiditis is an autoimmune disorder that sometimes causes hypothyroidism.

Is TSH 6.5 high?

Thyroid stimulating hormone (TSH), is the most common test that is ordered if your healthcare provider thinks that your thyroid gland is not functioning properly. A gland, called the pituitary gland, secretes TSH.



Normal Levels of Thyroid Hormones*

T3 95-190 ng/dl
T4 5-11 µg/dl
FT4I 6.5-12.5

Is TSH 7.5 high?

According to Cappola, her research regarded mildly elevated TSH levels as those in the 4.5 to 7 mU/L range, while very elevated TSH levels were considered to be those greater than 20 mU/L.

What TSH level is considered subclinical hypothyroidism?

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 are the side effects of a high TSH level?


High TSH levels indicate hypothyroidism.

  • fatigue.
  • weight gain.
  • swelling of the face and neck.
  • increased sensitivity to cold temperatures.
  • dry skin.
  • thinning hair.
  • a slow heart rate.
  • irregular or heavy menstrual periods.

What should I do if my TSH is high?

If your TSH level is high, the treatment is usually to prescribe pure synthetic T4 (levothyroxine sodium, called LT4), which is a manufactured version of the T4 hormone your thyroid produces. If your T3 level is low, the doctor can give you Liothyronine, which is only a short-term treatment for low T3 levels.

How can a woman lower her TSH level?

Low thyroid hormones can affect your body’s

levels. Taking a vitamin B-12 supplement may help you repair some of the damage hypothyroidism caused. Vitamin B-12 can help with the tiredness thyroid disease can cause.

Is TSH 5.6 high?

The subjects were split into two groups: those with a low-normal TSH (0.34–2.5 mIU/) and those with a high-normal TSH (2.51–5.6). Everyone underwent extensive testing to measure their general health status and well-being (by questionnaire), mood, and cognitive function.

What are high TSH levels?

High TSH levels can mean your thyroid is not making enough thyroid hormones, a condition called hypothyroidism. Low TSH levels can mean your thyroid is making too much of the hormones, a condition called hyperthyroidism.

What is the highest TSH level?

High Levels of TSH

TSH levels typically fall between 0.4 and 4.0 milliunits per liter (mU/L), according to the American Thyroid Association. Ranges between laboratories will vary with the upper limit generally being between 4 to 5. If your level is higher than this, chances are you have an underactive thyroid.

What TSH level is considered severe hypothyroidism?

TSH > 4.0/mU/L with a low T4 level indicates hypothyroidism.

If your TSH is > 4.0 mU/L and your T4 level is normal, this may prompt your physician to test your serum anti-thyroid peroxidase (anti-TPO) antibodies.

What does a TSH level of 40 mean?

Patients who show too much response to TRH (TSH rises greater than 40) may be hypothyroid. This test is also used in cancer patients who are taking thyroid replacement to see if they are on sufficient medication. It is sometimes used to measure if the pituitary gland is functioning.

Is TSH of 30 high?

High level of thyroid stimulating hormone (TSH) (≥30 mIU/L) is recommended for success of ablation treatment.

Is TSH 20 high?

Although not specifically reported as a harm by the authors of the guideline, progression to overt hypothyroidism (TSH elevation > 20 mIU/L or low free thyroid hormone levels), would be a risk in untreated patients. Overt hypothyroidism is associated with increased risk of symptoms (5) and morbidity.
