A New Way to Draw Blood—Without the Clinic

Getting blood drawn is a routine part of healthcare, but it's rarely convenient. From scheduling appointments to sitting in waiting rooms, the process adds friction to routine diagnostics. Tasso, a Seattle-based medtech company, is reimagining this process with Tasso+, a device that lets individuals collect blood samples themselves, from the comfort of home.

The innovation offers a simpler, more comfortable way to complete diagnostic testing, potentially transforming how patients interact with healthcare.

Designed for Simplicity

Tasso+ is a small, adhesive-backed device that attaches to the upper arm. With the press of a button, it activates a painless lancet and vacuum system that draws blood into a collection vial. The entire process takes just a few minutes and doesn't require any specialized training.

Once the sample is collected, it can be mailed to a laboratory for standard analysis, making it ideal for telehealth, chronic condition monitoring, or decentralized clinical trials.

Clinically Validated

Recent studies have evaluated the Tasso+ device for clinical use. One, published in Microbiology Spectrum, tested its effectiveness in monitoring CMV (cytomegalovirus) in transplant patients. The study showed a 91% match rate between Tasso+ and standard venous draws, with patients reporting higher satisfaction due to ease and comfort.

This level of reliability positions Tasso+ as more than a convenience—it's a legitimate alternative for specific diagnostic needs.

Approved and Available

Tasso+ is FDA Class II 510(k)-cleared, CE Marked in the EU, and registered with the UK’s MHRA. It's compatible with multiple lab formats and is intended for single-use prescription collection in home and remote care environments.

By reducing the need for in-person blood draws, the device has the potential to lower healthcare costs, improve patient compliance, and increase access, especially for those in rural or mobility-limited settings.
