Leuko
Leuko is a Massachusetts company developing PointCheck, a fingertip device that checks white blood cell levels without a blood test, so people having chemotherapy can be warned at home when their infection risk is high.
Also called: LEUKO LABS, INC.Leuko Labs
Overview
Leuko Labs, Inc., an MIT spin-out in Cambridge, Massachusetts, is developing PointCheck, an investigational noninvasive device that shines light into the skin near the fingernail, images blood flow in superficial capillaries and uses AI to assess whether white blood cell levels are dangerously low. The company says it is backed by a Series A round and NIH and NCI SBIR funding. In fiscal year 2026 the National Cancer Institute funded its SBIR project on reducing febrile neutropenia in people treated with chemotherapy with PointCheck (5R44CA228920-06, USD 991,877).
