The thyroid is a small, butterfly-shaped gland located in the lower front of your neck. It produces hormones that regulate how your body uses energy. When your thyroid gland doesn't work properly, it can affect every part of your body.
## What is a Thyroid Panel? A standard thyroid panel typically includes tests for: - **TSH (Thyroid Stimulating Hormone):** Produced by the pituitary gland, this hormone tells your thyroid how much T3 and T4 to make. - **T4 (Thyroxine):** The primary hormone produced by the thyroid gland. - **T3 (Triiodothyronine):** The active thyroid hormone, mostly converted from T4 in the liver.
## Why Should You Get Tested? Symptoms of thyroid disorders can be vague and are often confused with other health issues. You should consider a thyroid test if you experience: - Unexplained weight gain or weight loss - Chronic fatigue or sudden surges of energy - Hair loss or dry skin - Irregular heart rates
## Normal Ranges While reference ranges can vary slightly between laboratories, typical normal ranges for adults are: - TSH: 0.4 to 4.0 mIU/L - Total T4: 4.5 to 11.2 mcg/dL - Total T3: 75 to 200 ng/dL
If your test results fall outside these ranges, it's essential to consult a healthcare professional for a proper diagnosis and treatment plan. Regular screening can help catch thyroid issues early.
