First seen Jul 14, 2026 · Last updated Jul 16, 2026 · Updated 2 times

Summary

This study tests whether a non-invasive device that uses light to measure hemoglobin through the skin can accurately detect anemia. Researchers will compare its readings with standard blood tests in 150 adults in Jakarta. If the device proves reliable, it could offer a quick, painless way to screen for anemia in community settings.
