Finger-Prick blood test accuracy under the microscope
NCT ID NCT07287631
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aims to see how precise a small, portable device is at measuring potassium and calcium levels in blood from a finger prick. About 425 adults will provide a single blood sample, and the results will be compared to standard lab tests. No treatment or intervention is involved, so the study is purely about improving diagnostic accuracy.
