Whoop opens blood-testing service to what it says is a 350,000-person waitlist

Fitness band maker Whoop formally opened Whoop Advanced Labs for business on Tuesday. Some 350,000 people were on the waiting list after the service was previewed in May, the company told TechCrunch.

Whoop Advanced Labs offers health-screening blood tests from Quest Diagnostics that cover a variety of markers from calcium to white blood cells. The platform integrates those results with the band’s continuous monitoring of activity, sleep, respiratory rate, and blood pressure to offer more personalized wellness advice.
