Capillary Blood Accuracy

Entia is a health technology company that has developed a blood testing device called Entia Liberty, which analyses blood collected by a finger prick. Entia is sponsoring this research study to compare the results from Entia Liberty finger prick tests to results from the gold-standard laboratory analyser that tests blood from the arm, port, or PICC line.

Why the study stopped: Change in trial pipeline. Study no longer required.

Treatment and study plan

Entia Liberty System

Device

Participants will donate finger-prick blood samples to be tested on the Entia Liberty System. The results will not be used to inform clinical decisions or affect routine clinical care in any way.

Primary outcomes

Validity of of the Liberty System for haematological parameters of interest: Hb, WBC, PLT, ANC

Time frame: Through study completion, up to 8 days per participant.

The accuracy of the Liberty System will be measured by comparing the results of finger-prick blood samples that have been analysed using the Liberty System to the results of venous (blood from the arm, port or PICC line) blood samples that have been analysed by a standard laboratory haematology analyser.
Reliability of of the Liberty System for haematological parameters of interest: Hb, WBC, PLT, ANC

Time frame: Through study completion, up to 8 days per participant.

To measure the precision of the Liberty System by comparing the results of finger-prick blood samples that have been analysed by the Liberty System to each other, and to venous (blood from the arm, port or PICC line) blood samples that have been analysed by the Liberty System.
