Collection Information

Venipuncture: Thoroughly cleanse the area with a Betadine® scrub or similar preparation followed by a rinse with 70% alcohol (ethanol may be used instead of isopropyl and is less toxic). Collect 1 to 10 mL of blood into a heparinized tube. Invert the tube several times to prevent coagulation. If a Vacutainer® is used, let off any remaining vacuum by inserting a hypodermic needle or loosening the top briefly.
Skin lancet puncture: Thoroughly cleanse the site (finger, earlobe, or newborn child’s heel) by the above method. Rinse a sterile Pasteur pipet or TB syringe with approximately 0.5 mL of sterile heparin, and aspirate blood into it. Care must be taken to use only blood within the sterilized site; dripping blood may be removed with a sterile gauze pad. The blood-heparin mixture may be placed into a sterile tube for transport.
