Space blood test: can untrained volunteers prick their fingers in zero gravity?
NCT ID NCT06431984
First seen Nov 01, 2025
Summary
This study tested whether healthy volunteers with minimal training could collect their own capillary 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 after drinking coffee. If the method works, it could make it easier to study how drugs behave in space.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If successful, this method could enable simpler drug metabolism studies in space, helping understand how medications work in astronauts.
What could go wrong
This is a small feasibility study with only 30 participants, not a treatment trial. The method may not work reliably in real spaceflight conditions.
