## TL;DR

PointCheck is an investigational fingertip device from Leuko that checks for dangerously low white blood cell counts without a blood draw, for people having chemotherapy.

## Summary

PointCheck is being developed by Leuko as a portable device for use at home that estimates white blood cell levels optically through the skin near the fingernail. The National Cancer Institute funds an SBIR project on using it to reduce febrile neutropenia in people treated with chemotherapy (5R44CA228920-06). It is investigational and not for sale.
