New Women’s Health Blood Test Panel

Fitness wearable maker Whoop is launching a new panel focused on women’s health through its Whoop Labs blood testing service. The panel includes 11 blood biomarkers that can give insights into aspects such as cycle regulation and hormonal transitions:

• Anti‑Müllerian Hormone (AMH)
• Progesterone
• Prolactin
• Thyroid Peroxidase Antibodies (TPOAb)
• Free T4
• Free T3
• Leptin
• Vitamin B12 (Cobalamin)
• Folate
• Magnesium
• Phosphate (as Phosphorus)

Measuring these biomarkers is intended to help users understand perimenopause, thyroid function, nutrient sufficiency, and bone metabolic resilience when paired with data on activity, sleep, and recovery.

Hormonal Symptom Insights Feature

Whoop’s new “Hormonal Symptom Insights and Predictions” feature creates a model of hormonal changes over menstrual cycles based on a user’s historical data. The model predicts possible date windows for the next period, provides insights into cycle length, period length, irregularities, and details individual symptom patterns.

The company says it can tie insights from this feature into lab results, categorizing biomarker results as optimal, sufficient, or out of range.

Whoop also released a new menstrual cycle white paper that explains the modeling behind these features: Whoop 2025 White Paper – Menstrual Cycle Insights.

Availability and Background

The test will be available for purchase from next month. When Whoop launched its blood testing service in September 2025, it had over 350,000 people on the waitlist.

Industry Context

Fitness wearable companies have recently been adding more features and services catering to women’s health to address demand from this long‑underserved user base. Earlier this month, smart‑ring maker Oura released a new AI model focused on women’s health, along with a chatbot that provides health‑data insights and answers questions.

Whoop reported a 150 % increase in women using its products compared to a year earlier, making women its fastest‑growing user segment. Women also engage 30 % more with Whoop’s AI feature.

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.
