TRH stimulation test involves measuring basal TSH levels and then taking a second measurement of TSH levels after the patient is given an injection of synthetic TRH. The
synthetic TRH works the same way as endogenous TRH. If it is expected that Barbara
has a hormone suppressing tumor in either the hypothalamus or anterior pituitary,
what results would you expect for each type of tumor scenario after a TRH stimulation
test? Fill out the table below (state "high" or "low").
