Vacuum-Assisted Needle-Free Capillary Blood Sampling
Authors' conclusion
Vacuum significantly enhances the volume of capillary blood released from the fingertip without any difference in pain. The blood collected by jet injection with vacuum is equivalent to that from lancing for glucose measurement purposes.
Study context
- Population
- Participants divided into three equal groups exploring different vacuum pressures4 interventions each
- Participants
- 15 participants
- Comparison
- Fingertip jet injection vs lancing, with and without vacuum
- Outcome
- Blood glucose concentration and collected volume
Methodological detailssingle-blind, each participant own control
- Single-blind
- Each participant own control
Main finding
As reported in the abstract
40 kPa vacuum after jet injection: increase in collected volume
35-fold
Mean dilution of blood collected by jet injection
5.5%
Further findings
Acceptability
- Jet injection as acceptable to patients as lancing
