Thorn test

Thorn test

(thorn),
a putative test of adrenal cortical function; stimulation of a normally functioning adrenal cortex by the adrenocorticotrophic hormone is followed by a reduction in the number of circulating eosinophils and lymphocytes and an increase in the excretion of uric acid. The test lacks sufficient specificity and is rarely used.

Thorn test

a test of adrenal cortical function which originally measured the glands' response to ACTH by the change in the eosinophil count of blood samples taken before and after the injection. The modern version of the test measures the response by estimating plasma cortisol levels.
