First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested whether healthy volunteers with minimal training could collect their own blood using a finger prick during brief periods of weightlessness on parabolic flights. The goal was to see if the blood samples were good enough to measure caffeine levels. Thirty participants took part, and the study focused on how well the self-sampling worked in microgravity compared to on the ground.
