CPT® Code 82634

The CPT® Code 82634 refers to a laboratory test that measures the levels of 11-desoxycortisol in the blood. This substance, known as deoxycortisol, is a crucial precursor in the biosynthesis of cortisol, which is a glucocorticoid steroid produced by the adrenal glands. Cortisol plays a vital role in various bodily functions, including the regulation of metabolism, immune response, and stress response. The measurement of 11-desoxycortisol is particularly significant in evaluating adrenal function, as abnormal levels may indicate conditions such as congenital adrenal hypoplasia, a disorder affecting adrenal gland development and function. To perform this test, a blood sample is collected through a procedure known as venipuncture, which is separately reportable. The analysis of the blood sample is conducted using quantitative tandem mass spectrometry, a sophisticated technique that allows for precise measurement of the hormone levels in serum or plasma.
