No-Needle lactate test: mayo clinic trial pulled before start
NCT ID NCT05036122
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aimed to test a device called LabClasp that estimates blood lactate levels without a needle, using fluid from the skin. It was designed for healthy people during exercise and for ICU patients. However, the trial was withdrawn before any volunteers were enrolled, so no results are available.
