TRH stimulation test is used in the diagnosis of central hypothyroidism in patients with Sheehan’s syndrome. This test is used for suspected Hypothalamic-Pituitary dysfunction. It helps to differentiate between Secondary Hypothyroidism (Pituitary problem) and Tertiary Hypothyroidism (Hypothalamus problem) when TSH & T4 levels are not enough to draw a firm conclusion. |
