Whoop launches women's health blood panel
Whoop is launching a women's health blood panel with 11 biomarkers and a new hormonal tracking feature, targeting its fastest-growing user segment.
Fitness wearable maker Whoop is expanding its Whoop Labs blood testing service with a new panel focused on women’s health. Alongside the panel, the company is introducing a new feature in its mobile application called Hormonal Symptom Insights and Predictions. This feature models hormonal changes over menstrual cycles based on previous data to predict possible date windows for the next period, provide insights into cycle lengths and irregularities, and detail individual symptom patterns. The new blood test will be available for purchase starting next month. When Whoop first launched its blood testing service in September 2025, it had over 350,000 people on its waitlist, indicating strong initial demand for the company’s biological testing services.
The new panel measures 11 blood biomarkers related to cycle regulation and hormonal transitions. According to the company, measuring these specific biomarkers—when paired with existing user data on activity, sleep, and recovery—helps users understand perimenopause, thyroid function, nutrient sufficiency, and bone metabolic resilience. The 11 biomarkers included in the panel are:
- Anti-Müllerian Hormone (AMH)
- Progesterone
- Prolactin
- Thyroid Peroxidase Antibodies (TPOAb)
- Free T4
- Free T3
- Leptin
- Vitamin B12 (Cobalamin)
- Folate
- Magnesium
- Phosphate (as Phosphorus)
The expansion of these features comes as fitness wearable companies increasingly target a “long-underserved part of the userbase.” Whoop reported on Tuesday that it saw a 150% increase in women using its products compared to a year earlier, making women its fastest-growing user segment. The company also noted that women engage 30% more with its Whoop AI feature. This growth and feature expansion places Whoop in closer competition with Oura, a smart ring maker and competitor in the women’s health wearable market. In October 2025, Oura’s chief commercial officer, Dorothy Kilroy, told TechCrunch that the company’s fastest-growing user base was women in their twenties, highlighting how both companies are actively competing for the same demographic.
