Across the internet, a biological scapegoat has emerged for almost any mysterious medical symptom affecting women. Struggling with chronic fatigue, hair loss, brain fog, or dwindling sex drive? When no obvious explanation is at hand, an out-of-whack endocrine system must be to blame. Women have too much cortisol, vloggers and influencers say; or not enough thyroxine, or the wrong ratio of progesterone to estradiol. Social media is brimming with advice from self-proclaimed hormone “gurus” and health coaches; the tag #hormoneimbalance has racked up a staggering 950 million views on TikTok alone.
Now dozens of start-ups promise to diagnose these imbalances from the comfort of your home. All it takes is the prick of a finger, a urine sample, or a vial of spit. You mail your sample out to a lab or run the test right in your kitchen, no co-pay or doctor visit required. A few days later, you receive a slick lab report and in some cases, a customized treatment plan to alleviate the depression, the insomnia, the feeling of just being off.
Hormone imbalances can indeed contribute to an array of mental and physical symptoms, and hormone testing overseen by providers is a routine practice in medicine. Doing so remotely could theoretically improve women’s health and access to care. But despite their growing popularity and Amazon-like convenience, at-home hormone tests might cause more problems than they solve. Several women’s-health and hormone specialists told me that remote testing has long been useful for detecting pregnancy and tracking ovulation, but that few, if any, products now for sale have been consistently and rigorously proven to work for broader, newly advertised purposes. Testing kits are marketed as a way of helping women decipher puzzling symptoms or assess their fertility. But experts said that the technology—at least as it stands right now—is unreliable and could have the opposite effect, causing anxiety and confusion instead.
