Whoop is launching a new blood test that focuses on women’s health

Fitness maker Whoop is launching a new division focused on women’s health through its blood testing service Whoop Labs. The company is adding a new feature to its app that displays information about hormonal changes during the menstrual cycle.

The founders said that the group includes 11 blood markers that can provide information on things like circulation control and hormonal changes: Anti-Müllerian Hormone (AMH), Progesterone, Prolactin, and Thyroid Peroxidase Antibodies (TPOAb), Free T4, Free T3, Leptin, Vitamin B12, Magnesium Foslate, Cobalac Foslate, Cobalactin (Cobalactin) Phosphorous).

The company says measuring these biomarkers will help users understand more about perimenopause, thyroid function, nutrient adequacy, and bone metabolic health, when combined with data on activity, sleep, and recovery.

The test will be available to users for purchase starting next month. When Whoop started his blood test in September 2025it had more than 350,000 people on the waiting list.

Meanwhile, the new Hormonal Symptom Insights and Predictions feature of the Whoop apps creates a model of hormonal changes during menstruation based on previous events. They use this model to predict possible windows for the next period, provide information on the length of time, length of time and errors, and details of individual symptoms.

The company said it can tie information from the panel into laboratory results to change biomarker results to ‘adequate,’ ‘adequate,’ or ‘abnormal’.

Whoop released it again white paper for the new period to provide insights into the corporate design behind these new products.

Fitness apparel companies have recently been working to add more features and services to support women’s health to meet demand from this long-neglected segment of users. Earlier this month, the smart ring maker Oura was released a new type of AI for women’s healthalong with a chatbot that can provide health information and answer questions.

Whoop said on Tuesday that it has seen a 150% increase in women using its products compared to a year ago, making it its fastest growing segment. The company found that women engage 30% more with its Whoop AI feature.

In October 2025, Oura’s chief marketing officer, Dorothy Kilroy, he told TechCrunch that the company’s fastest growing users were women in their twenties.
