Meet Scarlet Scarlet® is an on-demand, mobile laboratory specimen collection service that gives patients the option to have provider-ordered lab test specimens collected when and where they choose – from the home or workplace. Safe, easy, convenient, and backed by BioReference Laboratories, Scarlet helps empower patients to take control over their healthcare. How Scarlet Works A patient needs a lab order from a healthcare provider and a smartphone or computer to schedule with Scarlet. A healthcare provider can either order Scarlet themselves or provide the lab order to the patient to upload it at ScarletHealth.com. Once uploaded, Scarlet will reach out directly to the patient via text or email to schedule an appointment. After scheduling, a Scarlet Health Professional will contact the patient to share details about the visit, including specific lab specimen collection instructions. On the day of the appointment, patients can even track the arrival of their Scarlet Health Professional through a digital map.
