How is thyroid on lab results?

A normal TSH and normal T4 indicates a normally functioning thyroid gland. A low TSH and high T4 generally indicates hyperthyroidism. A high TSH and low T4 indicates primary hypothyroidism (due to a thyroid disease).

How do I know my thyroid report?

Sometimes a free T4 level is also checked along with the T4 test. The TSH test measures the level of thyroid-stimulating hormone in your blood. The TSH has a normal test range between 0.4 and 4.0 milli-international units of hormone per liter of blood (mIU/L).

What should the results of a thyroid test be?

A Thyroid Stimulating Hormone, or TSH, is a hormone that is commonly tested by doctors to check the health of your thyroid. A normal TSH test result is between .4 and 4.0. Another hormone that your doctor may test is your T4, which is produced directly by your thyroid.

What happens when you have too much or too little thyroid?

Thyroid level tests, including the TSH test, can determine if your thyroid is producing too much or too little thyroid hormone. If your thyroid gland doesn’t produce enough T3 or T4, hypothyroidism (underactive thyroid) can result. If your thyroid gland produces too much T4, hyperthyroidism (overactive thyroid) can result.

What causes high thyroid results?

Graves disease is the most common cause of hyperthyroidism. It is a chronic autoimmune disorder in which the affected person’s immune system produces autoantibodies that act like TSH, bind and activate the TSH receptor, leading to the production of excessive amounts of thyroid hormone.

What do your Thyroid Lab results really mean?

When one considers the thyroid test results, as given by the TSH blood test plus the levels obtained in the FT4 thyroid labs, this can give a greater sense of where thyroid gland function is at. In other words, if the TSH is raised, but the Free T4 is low, then this can indicate a primary form of thyroid gland malfunction, or primary hypothyroidism.
