Zaro Health is a personalized health testing service that combines lab-grade bloodwork, wearable data, and lifestyle information to help people understand and improve their health. Customers can order online without a doctor’s visit, choose a blood draw at a compatible Quest location, and receive results in the Zaro app, typically within five to seven business days. The service offers three testing panels: Surface for a foundational health snapshot, Signal for additional early-warning markers, and Source for deeper investigation of potential underlying factors. Depending on the panel, testing covers areas such as heart and metabolic health, blood, kidneys, liver, thyroid, hormones, stress, and nutrients.

Zaro brings test results and compatible wearable signals together in a personalized Zaro Score, rated from 0 to 100 across seven health domains. Its app provides plain-language explanations, tracks changes over time, and offers recommendations linked to individual results. The platform also supports follow-up prompts intended to help users act on those recommendations.
