What is a good thyroid test result?

A normal range for TSH in most laboratories is 0.4 milliunits per liter (mU/L) to 4.0 mU/L. If your TSH is higher than 4.0 mU/L on repeat tests, you probably have hypothyroidism. Your doctor may also order a T4 test. Most of the T4 in your blood attaches to a protein, and when it does, it can’t get into your cells.

What are normal TSH and T4 levels?

Generally, healthy TSH levels are an indicator the whole system is working well, but that’s an oversimplification at best. A normal T3 level might be somewhere between 100 to 200 nanograms per deciliter (ng/dL), while a normal T4 level falls between 5.0 to 12.0 micrograms per deciliter (μg/dL).

What levels indicate thyroid problems?

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 time of day is best for thyroid test?

I recommend getting your thyroid function tests done first thing in the morning, bringing your medications with you, and taking them right after you have your thyroid function tests to ensure that you get accurate test results.

What is a normal T4 free level for a woman?

The normal range for free T 4 in adults is 0.8 to 1.8 nanograms per deciliter (ng/dL). A level of free T 4 that is higher than normal could mean you have an overactive thyroid.

Is a TSH level of 11 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 a TSH level of 3.2 normal?

The normal range of TSH levels is 0.4 to 4.0 milli-international units per liter. If you’re already being treated for a thyroid disorder, the normal range is 0.5 to 3.0 milli-international units per liter. A value above the normal range usually indicates that the thyroid is underactive. This indicates hypothyroidism.

What are the normal and optimal thyroid TSH levels?

In a healthy person TSH, T3 and T4 are optimal and body temperature is 98.6. In hypothyroidism the body temperature is below optimal 98.6 but remains stable. In low adrenal function the body temperature is low and unstable but TSH, T3 and T4 are low.

Is my thyroid level really normal?

If you’re already being treated for a thyroid disorder, your doctor will probably consider your TSH level to be normal if it’s somewhere between 0.5 to 3.0 mIU/L . This may vary based upon your age and gender. TSH levels are only one indicator of how your thyroid is functioning. They vary by gender, age, and other factors.

What is a normal thyroid reading, from a blood test?

TSH Reading. A TSH test measures the amount of TSH produced by the pituitary gland. This is also a blood test. The normal range for TSH is between 0.5 and 5.0.

What is the most accurate test for thyroid levels?

Most doctors consider the sensitive thyroid-stimulating hormone (TSH) test to be the most accurate measure of thyroid activity. By measuring the level of TSH , doctors can determine even small problems in thyroid activity.
