How PointCheck™ Works

Noninvasive insight into your immune health.

PointCheck™ is the first noninvasive device for screening severe neutropenia. By imaging blood flowing through capillaries in the finger, it determines whether white blood cell levels are dangerously low, completely noninvasively, with no blood draw.

Noninvasive. No needle. No blood draw.

A short video sequence of the nailfold microcirculation captures individual blood cells as they pass through superficial capillaries. Our AI models detect optical signatures associated with white blood cells and quantify their concentration.

If severe neutropenia (a critically low level of neutrophils, the most common subtype of white blood cell) is detected early and monitored routinely, clinicians can intervene sooner and prevent severe infections such as febrile neutropenia through timely treatment.

Made for monitoring between visits.

PointCheck™ is portable and simple, enabling care teams to regularly monitor suspected neutropenia in outpatient settings, and support earlier clinical intervention.
