Why Is It Important To Puncture Across The Fingerprint Lines? To obtain the best capillary specimen using the finger, align the puncture device perpendicular (horizontal) to the whorls of the fingerprint. This cross-cut of the fingerprint whorls causes the blood to bead at the puncture site, allowing the phlebotomist to efficiently collect the drops of

How Do Capillary Tubes Collect Blood? The capillary tube uses capillary action to draw the blood into the micro tube thereby eliminating the tendency for scooping. Because the capillary tube is also coated with anticoagulant, the blood sample mixes with it immediately to prevent clotting. How is capillary puncture done? The puncture must be on
What Does Warming A Site For Skin Puncture Do? What does warming a site for skin puncture do? Before capillary puncture is performed, the site may need to be warmed in order to increase arterial blood flow to the puncture area. There are several commercially available thermal packs also known as “heel warmers”, but a
