Whoop launches a new blood test focused on women’s health

Whoop, known for its fitness wearables, is set to introduce a groundbreaking blood test panel specifically designed to address women's health issues through its Whoop Labs service. This new offering will feature a dedicated app enhancement that provides users with critical insights into hormonal fluctuations during menstrual cycles. The blood panel encompasses 11 key biomarkers, including Anti-Müllerian Hormone (AMH), Progesterone, Prolactin, and Thyroid Peroxidase Antibodies (TPOAb), along with Free T4, Free T3, Leptin, Vitamin B12, Folate, Magnesium, and Phosphate. These biomarkers are intended to deepen understanding of perimenopause, thyroid health, nutrient levels, and bone metabolism when analyzed alongside data on user activity, sleep patterns, and recovery metrics. Available for purchase starting next month, this initiative follows the company's initial launch of its blood testing service, which saw an impressive waitlist of over 350,000 sign-ups in September 2025. Additionally, the app's new Hormonal Symptom Insights and Predictions feature leverages historical data to model hormonal changes throughout menstrual cycles, offering predictions for upcoming periods, cycle lengths, and individual symptom patterns. The insights from this feature can be correlated with laboratory results, categorizing biomarker outcomes into ‘optimal,’ ‘sufficient,’ or ‘out of range’ classifications. To further support its users, Whoop has also released a white paper detailing the modeling techniques behind these innovative features. The push for advanced offerings in women's health is gaining momentum across the fitness wearable industry. Just recently, smart ring manufacturer Oura introduced an AI-driven model aimed at women’s health, complete with a chatbot to provide personalized health data insights. Remarkably, Whoop reported a 150% surge in female users over the past year, marking the fastest-growing segment of its customer base. The company also highlighted that women interact with its Whoop AI feature 30% more than other users. Oura’s chief commercial officer, Dorothy Kilroy, noted that their fastest-growing demographic consists of women in their twenties, indicating a significant shift toward addressing the needs of this previously underserved group.
