What Is a Normal Thyroid Level?

The thyroid gland releases hormones that are crucial for our bodies to function properly. They're essential for regulating cells and the "speed of life." For example, when you have hypothyroidism, you may feel that you're simply "slowing down." The opposite is true with hyperthyroidism.

TSH Count

Thyroid levels are measured by a TSH count. TSH stands for thyroid-stimulating hormone, which regulates the thyroid gland. TSH levels can be measured with a blood test.

Normal Thyroid Level

A normal TSH count is usually between 0.4 and 5.0.

Hypothyroidism

People with mild hypothyroidism have a TSH count between 5 and 15. Moderate hypothyroidism is between 15 to 20. Severe hypothyroidism is 50 or above.

Hyperthyroidism

Hyperthyroidism is associated with a low TSH count, usually less than 0.2.

Medical Care

It's important to discuss possible thyroid problems with your doctor if you suspect you have any symptoms of a malfunctioning thyroid gland. Your doctor may want to draw blood to test your TSH count.
