Monitor white blood cell levels without a blood draw.

The first noninvasive device for white blood cell measurement. Fast, portable, and easy to use, PointCheck™ brings critical immune-system insights out of the lab and into patients' homes.

How it works For Patients & Caregivers For Clinicians

A person uses the PointCheck device on a kitchen counter at home. — PointCheck™ is designed for use at home.

At-home test

A simple, finger-based test.

Portable and designed for home use, PointCheck™ noninvasively evaluates white blood cell levels.

No blood sample

Light-based, not lancets.

By shining light into the skin near the fingernail, PointCheck™ images blood flow in superficial capillaries and uses AI to assess whether white blood cell levels are dangerously low.

Clinically relevant

Enable earlier intervention.

Risk of infection is a major worry for cancer patients. PointCheck™ helps surface elevated risk early, supporting timely preventive care.
