Is TSH 7 too 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.
Is 7.5 TSH 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.
What is considered a very 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.
What does a TSH of 7.2 mean?
The doctor ordered a hormone panel and found a blood thyroid-stimulating hormone (TSH) level of 7.2 microunits per milliliter (mlU/L). TSH triggers the thyroid to make hormones that control metabolism, so elevated TSH is considered a sign the thyroid might be making too little thyroid hormone.
What does a TSH level of 20 mean?
Suspected and known hypothyroidism: a TSH level > 20 milli-International Units/L in association with a low free thyroxine (T4) confirms the diagnosis of hypothyroidism.
What if your TSH is 40?
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 25 high?
The typical range of reference for TSH levels is anywhere between 0.45 and 4.5 milliunits per liter (mU/L) . A recent study suggests that the normal range should be more like 0.45 to 4.12 mU/L. TSH can vary wildly based on your age, sex, and stage of life.
What is a normal TSH level for a 60 year old woman?
Low TSH levels usually mean that you’re producing too much thyroid hormone.
| Age range | Normal | High |
|---|---|---|
| 18–30 years | 0.5–4.1 mU/L | > 4.1 mU/L |
| 31–50 years | 0.5–4.1 mU/L | > 4.1 mU/L |
| 51–70 years | 0.5–4.5 mU/L | > 4.5 mU/L |
| 71–90 years | 0.4–5.2 mU/L | > 5.2 mU/L |
What does a TSH of 40 mean?
What is the normal range for TSH levels?
TSH levels are measured in ranges. In general, the normal reference range for TSH levels is 0.5 to 5.0 milli-international units per liter (mIU/L) of blood. A TSH reading in this range indicates the thyroid gland is functioning normally.
What is the difference between a low TSH and a high TSH?
Once you understand these thyroid basics, it’s easier to understand what a low TSH and a high TSH reveal about your thyroid’s function. The normal range for TSH is between 0.5 mU/l and 5.0 mU/l. 1 A high TSH suggests your thyroid is underactive ( hypothyroid) and not doing its job of producing enough thyroid hormone.
What should I do if my TSH is high or low?
If a person has abnormally high or low TSH levels, the doctor needs to run at least one other diagnostic test to identify the underlying cause. These tests look at levels of specific thyroid hormones and antibodies. Doctors can treat hypothyroidism with medications, such as levothyroxine, that replace the missing thyroid hormones.
Are TSH levels higher or lower in early pregnancy?
TSH levels tend to be lower in pregnant women. Pregnancy hormones naturally increase the levels of certain thyroid hormones in the blood. This is essential for the development of the fetal brain and nervous system. At the same time, the levels of TSH in the blood decrease.
