Characteristics of Different Types of Safety Lancets on Blood Volume and Perceived Pain in Male and Female Volunteers

Study Overview
=================
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.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Volume (microliters) of blood in the capillary tube | The amount of capillary blood volume collected after a single lancing of the fingertip. | The blood from the puncture site was collected to the capillaries by pressing during 2 minutes | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Pain perception: VAS | 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. | 5 minutes after lancing |
