Traditional blood testing of the thyroid shows how much hormone we have, but it doesn't tell us how well the thyroid hormone is working. So, even though a blood test may determine that you have good thyroid hormone levels, the Thyroflex test provides even greater insight.
Once tested, an extensive thyroid panel may be required to get a full picture of what’s going on with your thyroid which would include testing for TSH, free T4, free T3, reverse T3 (rT3), as well as thyroid antibodies to check for auto immunity.
