Brief summary
The study was a randomized, single blind, uni-center pivotal study in male and female healthy volunteers, to determine capillary blood volume and pain perception obtained in a process of puncturing with different safety lancets. A group of one hundred (100) healthy Caucasian male and female Subjects (aged \> 18 to \< 65 years old was randomized ) who were in good physical and mental condition. The Subjects had 4 (four) fingers (two fingers from each hand) lanced each with a different type of safety lancet. Overall, 4 (four) different safety lancets were investigated per each Subject. Overall, 16 (sixteen) different safety lancets (4 different safety lancets per one Subject) were investigated, the capillary blood volume and pain were measured.
Interventions
Finger lancing was undertaken in a standardized way and was performed by medical staff trained from lancing procedure described in the Protocol. Total blood collection time was recorded in the source documentation and then volume of the blood was measured using a calibrated ruler. Perceived pain was assessed on the visual analog scale (VAS, numeric scale). VAS scale was assessed 5 minutes after the lancing procedure.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Volume (microliters) of blood in the capillary tube | The blood from the puncture site was collected to the capillaries by pressing during 2 minutes | The amount of capillary blood volume collected after a single lancing of the fingertip. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Pain perception: VAS | 5 minutes after lancing | The intensity of pain perceived by the patient was assessed with the use of the numeric Visual Analog Scale (VAS). The Subject marked on the scale the number from 0 (no pain) to 10 (worst imaginable pain) that represented their perception of pain. A higher score indicated greater pain intensity. |
