Pregnenolone, MS

Pregnenolone is the vital starting block for all your body's steroid hormones. This test measures the level of pregnenolone in your blood using advanced Liquid Chromatography Tandem Mass Spectrometry (LC-MS/MS). It is primarily useful as an ancillary tool to evaluate for rare forms of congenital adrenal hyperplasia (CAH), especially when the more common types have been ruled out. Understanding your pregnenolone levels provides critical insight into endocrine function and hormonal balance. Doctors often use this analysis to help diagnose unexplained fatigue, infertility, or hormonal imbalances.
