When to Seek Prompt Care

No common urgent flag from this test alone. However, severe symptoms of hyperthyroidism (like rapid heart rate, tremors, or sudden weight loss) or hypothyroidism (like extreme fatigue, severe constipation, or feeling very cold) should prompt a call to your clinician.

What It Measures

This test checks how much thyroid stimulating hormone is in your blood. This hormone tells your thyroid gland to make thyroid hormones.

Why It's Ordered

Doctors often order this test to see how well your thyroid gland is doing its job. It helps them find out if you have thyroid problems. These problems include a thyroid that is not active enough or one that is too active.

Reference Range

Reference ranges for TSH can vary by laboratory, age, and pregnancy status. Your doctor will interpret your results based on these factors.
