Finger prick vs. needle: can a drop of blood replace the lab draw?
NCT ID NCT06544070
First seen Sep 11, 2026 · Last updated Sep 11, 2026
Summary
Researchers are testing whether a finger-prick blood testing device, the Entia Liberty System, gives accurate results compared with standard laboratory blood tests. Participants are adults receiving systemic anti-cancer therapy who already need routine full blood count tests. They donate finger-prick samples that are analyzed on the device, and researchers compare those results with venous blood samples analyzed by a standard laboratory analyzer. The study focuses on hemoglobin, white blood cell, platelet, and neutrophil counts.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Entia Liberty System, a finger-prick blood testing device
- What this could lead to
- If the device proves accurate, people receiving cancer treatment could one day check key blood counts with a finger prick instead of a needle draw from a vein, arm port, or PICC line.
- What could go wrong
- This is an early accuracy study, not a test of whether the device improves patient outcomes. Finger-prick results may not match laboratory results closely enough, especially at very low white blood cell counts.
