T4 Blood Test - More Information

The T4 total test, also known as the thyroxine lab test, measures the total T4 blood level.

T4, or thyroxine, is an important thyroid hormone. Total T4 blood levels are sometimes measured along with the free T4 test to get a more thorough picture of the thyroxine hormone levels in the body.

Getting a T4 test near you is a fast process as standard Quest Diagnostics labs have the necessary equipment to perform the lab test. After you get your blood drawn, T4 lab results come back relatively quickly. As can be seen on the thyroxine sample report provided in the link above, T4 levels are reported as a number in mcg/dL. In addition, the lab will provide a reference range so that you can compare your total T4 results against what the lab considers to be normal. As with any lab result, your T4 test should be interpreted in the context of any symptoms that you are having with the help of a licensed medical provider.
