When TSH concentrations are high, the thyroid will make and release excessive amounts of T4 and T3 and the patientIf after a TSH test result is low and a T4 test result is normal or low, a T3 test result is normal or low, it can indicate a non-thyroidal illness, for example a rare pituitary hypothyroidism.
