Early menopause can cause a wide range of physical and emotional symptoms long before menopause officially begins. Learn the most common warning signs, including irregular periods, hot flashes, mood changes, sleep problems, fatigue, and hormonal imbalances, and discover when hormone testing may help provide answers.

Saliva hormone testing is a non-invasive, scientifically validated method for measuring the bioavailable fraction of key hormones — including cortisol, oestrogen, progesterone, testosterone, and DHEA — from the comfort of home. Unlike standard blood tests, which measure total hormone levels including the inactive, protein-bound fraction, saliva testing reflects the hormones that are actually active in tissues and driving biological effects. Combined with LCMS (liquid chromatography tandem mass spectrometry) technology, saliva testing offers exceptional accuracy, sensitivity, and clinical relevance for assessing hormone balance, monitoring hormone therapy, and understanding the root causes of symptoms such as fatigue, mood changes, poor sleep, and hormonal imbalance.

Learn the key differences between EIA, ECLIA, and mass spectrometry hormone testing methods, and discover why ZRT Laboratory’s long-standing use of LC-MS, GC-MS, and ICP-MS delivers gold-standard accuracy for advanced hormone analysis.
