# Pregnenolone, Mass Spectrometry (Endocrine Sciences)

> This test measures the level of pregnenolone, a substance your body uses as a building block to make steroid hormones like cortisol and testosterone. It helps doctors evaluate how well your adrenal glands are functioning, particularly when symptoms suggest a problem with hormone production or a rare genetic condition. This measurement helps rule out or identify specific blocks in the chemical pathways that create essential hormones. However, this test alone cannot diagnose a specific disease and usually requires comparison with other hormone levels to pinpoint the exact cause.
