Thyroid-Stimulating Hormone Test - TSH

This test measures the level of thyroid-stimulating hormone (TSH) in the blood.

This test measures the level of thyroid-stimulating hormone (TSH) in the blood.

This test, by measuring the level of thyroid-stimulating hormone (TSH) in your blood, can determine how well your thyroid gland is functioning. When your thyroid gland is not working properly, your pituitary gland will increase the amount of TSH it makes. The TSH stimulates the thyroid gland to produce more thyroid hormones (T3 and T4).

In an adult, the blood sample is taken by placing a needle in a vein in the arm. In a newborn, the sample is taken by pricking the baby's heel.

  • Be sure to tell your healthcare provider about any medications you are taking. Some can interfere with the test.
  • This care path's costs do not include the charge to draw blood from a vein (venipuncture).
  • There will only be one charge to draw blood, even if multiple tests are being performed on the samples that are taken.

What should I ask my healthcare provider before having this test?

  • Is there any special preparation for the test? (If so, get clear instructions on what you need to do.)
  • What is the reason for the test? Will the test results change my treatment plan? If not, do I need the test?
