Thyroid Hormone Test - Thyroxine - T4
This test measures the blood level of a hormone made by the thyroid gland (Thyroxine, which is also known as T4).
This test measures the blood level of T4 (Thyroxine), a hormone made by the thyroid gland. It is often done along with or after a thyroid-stimulating hormone (TSH) test and Triiodothyronine (T3) test.
- Thyroid hormones help control how the body uses energy, and are also associated with managing body temperature, muscle function, heart rates and mental functioning.
- This test may be done with other thyroid tests to see how well your thyroid gland is working.
- It is also a common screening test in newborns.
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?
