Thyroid Calculator - TSH FT4 FT3
This calculator enables you to quickly determine how optimum you are in your blood range of Free T4 and Free T3. Since everyone in the world wants to know what the TSH is, we've included it here. Keep in mind that the lower the TSH, the less impact it has on thyroid function, unless you're suffering from Graves hyperthyroidism. In that case, a suppressed TSH will usually correspond with above-normal levels of both FT4 and FT3.
It is possible to have a suppressed TSH and normal levels of both FT4 and FT3 without symptoms of overstimulation. This is why it's important to always measure the three together.
