right In medicine, some blood tests are conducted on capillary blood obtained by<unk>  (or fingerprick) (or, for neonates, by an analogous heelprick). The site, free of surface arterial flow, where the blood is to be collected is sterilized with a topical germicide, and the skin pierced with a sterile lancet. After a droplet has formed, capillary blood is captured in a capillary tube (usually relying on surface tension). Blood cells drawn from<unk> s have a tendency to undergo hemolysis, especially if the finger is "milked" to obtain more blood. __TOC__
