    GlossaryAdrenal Vein Sampling

    diagnostic procedure collecting blood from adrenal veins for hormone analysis

    Adrenal Vein Sampling (AVS) is a diagnostic procedure used to determine the source of excess hormone production in the adrenal glands, often to diagnose conditions like primary aldosteronism. During the procedure, a catheter is inserted into the veins draining the adrenal glands to collect blood samples, which are then analyzed for hormone levels. This helps doctors decide the best treatment approach, such as surgery or medication.
