First seen Nov 06, 2025 · Last updated Jun 23, 2026 · Updated 29 times
Summary
This study tested a device called PointCheck that uses light to check for severe neutropenia (low white blood cells) in cancer patients without needing a blood sample. Researchers enrolled 81 adults with blood or breast cancers who were receiving chemotherapy. The main goal was to see how easy the device is to use, with a secondary look at how accurate it is. If it works well, it could allow patients to monitor their condition at home.
