Most conventional medicine doctors will only run a
few thyroid markers to determine the type and dosage of thyroid replacement hormone prescribed.
Therefore, we also test thyroid antibodies to screen for autoimmunity along with
other thyroid markers for more information.
For instance, many doctors only look at TSH, a
basic thyroid marker, when running a blood test for hypothyroidism.
Pregnant women should also test
other thyroid markers, such as T4 and T3, as well as TPO and TGB antibodies.
Since
my thyroid markers were «normal» and my antibodies were sky high (more than 1,000 IU / mL when they should be below 30 IU / mL), I was sent home with no treatment options.
In order to address the root cause of thyroid disturbances, a functional medicine specialist will order a full thyroid with up to 10
thyroid markers.
They ate the same amount of calories and
their thyroid markers still took a hit.
So you can see where the top end of TSH is in itself a conundrum, but the bigger problem in my opinion is that TSH is just one
thyroid marker — and while it's historically been the red flag to warrant more thyroid testing, with what we know now this practice just isn't enough.
For some, TSH may be normal but other
thyroid markers are off.
If you have high Total T4 and low Total T3, you may also want to look at
another thyroid marker called RT3 or reverse T3.
