Since thyroid hormones are used by every area of your body, it’s important to get a full picture of what’s going on beneath the surface. However, many underlying thyroid problems don’t show up on standard labs because conventional labs only look at TSH and T4.
But in functional medicine, we run a full thyroid panel blood test that looks at TSH and T4, as well as T3 uptake, total T3, free T4, free T3, reverse T3, and thyroid antibodies.
