What is considered a very high TSH level?

What is considered a very high TSH level?

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.

Is TSH 4.6 normal?

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 1.78 normal?

The normal range of TSH levels in adults is between 0.4 to 4.0 mIU/L (milli-international units per liter). Some research suggests that this range should actually be more like 0.45 to 2.5 mIU/L.

Is TSH 1.95 normal?

Serum TSH levels were classified as low-normal (0.34-1.19 mIU/L), middle-normal (1.20-1.95 mIU/L), high-normal (1.96-5.60 mIU/L), and subclinical hypothyroidism (>5.60 mIU/L).

Is TSH 1.83 normal?

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 should my TSH level be on levothyroxine?

In most patients on thyroxine replacement, the goal TSH level is between 0.5 to 2.5 mU/L.

Is TSH level 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 does a TSH level above 5.0 mean?

A TSH level above 5.0 mIU/L usually indicates an underactive thyroid gland, or hypothyroidism. High TSH levels can cause symptoms that include:

What does hypothyroidism and high TSH mean?

Hypothyroidism = low thyroid function = sluggish thyroid = low T3 and T4 levels of thyroid hormone in the blood = high TSH (all of these terms are ways to describe the same condition). The exact opposite is true when the TSH is low.

What kind of blood test do they do for high TSH?

When you see your doctor, the most common test for a high TSH level is a blood test. They will not only check your TSH level, but they also are looking at your triiodothyronine (T3) and thyroxine (T4) levels.

What’s the normal range for thyroid hormone 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. However, doctors do not all agree on the precise TSH range of a normal-functioning thyroid gland.
