There are two types of tests for T4.
- Total T4
- Free T4
Total testing is antiquated and no longer useful since the Free T4 test was devised. Total testing tells you how much total amount of T4 is in your blood. This includes the T4 that is bound to other proteins and hormones that cannot be used by the body, so is an inaccurate test.
Free testing is the current gold standard, most accurate way to test T4. It shows how much of the T4 is floating freely, ready to be used by the body by conversion to T3.

Is it better to choose a full thyroid panel or just a basic thyroid test?
It really depends on why someone is getting the test in the first place. Both a basic thyroid test and a thyroid panel serve different purposes, and the choice usually depends on what needs to be evaluated. A basic thyroid test typically measures TSH (thyroid-stimulating hormone), which is often sufficient for routine screening. If the values fall within the specified range and there are no abnormalities detected, this test alone is sufficient to give a general understanding of thyroid function. A full thyroid panel, on the other hand, is a more comprehensive test that includes additional markers like T3 and T4 (and sometimes Free T3, Free T4, or thyroid antibodies). This is usually suggested when a more detailed understanding of an individual’s thyroid function is needed. In many cases, doctors prefer starting with a basic thyroid test and then expanding to a full panel only if necessary. This also helps keep things practical, as the thyroid test price can vary depending on how comprehensive the test is.
