A positive experience when getting a blood sample taken is important for both the patient and the professional user.
In all types of capillary blood sampling, it is an advantage if the skin is warm and has good blood flow.
When the skin is warm, blood vessels supplying blood to the skin can swell or dilate (vasodilation). This allows more warm blood to flow near the surface of the skin.
Lectro Derm is a heating device to use when getting a blood sample taken.
