CPT® Code 82696

The CPT® Code 82696 refers to a laboratory test specifically designed to measure the level of etiocholanolone, which is an inactive androgenic ketosteroid. This compound is metabolized from testosterone and androstenedione through the action of the enzyme 5-beta-reductase. Understanding the levels of etiocholanolone in the body is significant because elevated concentrations can lead to various physiological responses, including fever, immunostimulation, and leukocytosis, which is an increase in white blood cells. Additionally, etiocholanolone is known to exert anticonvulsant effects by interacting with GABA receptors, thereby influencing seizure susceptibility. This makes the measurement of etiocholanolone particularly relevant in certain clinical contexts. Notably, individuals suffering from androgenic alopecia, commonly referred to as male pattern baldness, frequently exhibit elevated levels of etiocholanolone in their urine. The test requires the collection of a blood sample, which is obtained through a separately reportable venipuncture, while urine can be collected either by random voided specimen or through catheterization, depending on the clinical requirements.
