Understanding Thyroid Test Results

Having an accurate understanding of your thyroid test results is key to proper management and treatment of your thyroid-related health problems. This guide will help walk you through the basics of reading and interpreting thyroid tests and how these tests affect your overall health.

Why Are Thyroid Tests Necessary?

Your thyroid is a small, butterfly-shaped gland responsible for releasing hormones that regulate your body’s metabolism, growth, and development. Measuring your thyroid levels through tests is one of the most reliable ways to diagnose and treat thyroid disorders.

Understanding Your Results

Thyroid tests assess the levels of thyroid stimulating hormone (TSH) and two other hormones in the thyroid, triiodothyronine (T3) and thyroxine (T4). Your results will fall into either one of two categories: normal or abnormal. Many factors can cause abnormal results, including medication, age, pregnancy, recent surgery, or an underlying medical condition.

Common Tests and Their Results

TSH Test: This test measures levels of TSH, the hormone produced by the pituitary gland that tells the thyroid to produce T3 and T4. If you have too little TSH, you have hypothyroidism; too much TSH means hyperthyroidism. Normal TSH levels are between 0.5 to 5.0 milliunits per liter (mU/L).

T3 Test: This test measures your T3 levels. Low levels of T3 indicate hypothyroidism, while higher levels indicate hyperthyroidism. Normal T3 levels are between 100 to 200 nanograms per deciliter (ng/dL).

T4 Test: This test looks at the levels of T4, the main hormone produced by the thyroid. Low levels indicate hypothyroidism, while higher levels indicate hyperthyroidism. Normal T4 levels are between 5.0 to 12.0 micrograms per deciliter (µg/dL).

Treatment Options

If your thyroid test results fall outside of the normal range, your doctor will suggest a treatment plan. Treatment typically consists of either oral medications or a combination of medications and lifestyle changes.
