Collection of Blood Cultures

  1. Do not collect from a site that shows signs of possible infection such as swelling, redness, hardness, or heat because organisms may already be established in the subcutaneous tissue, which could contaminate the blood cultures.
  2. Clean the venipuncture site using a Blood Culture ChloroPrep Kit (item #56099).  Squeeze the handle of the scrubber once to release the isopropyl alcohol.  Use the scrubber to vigorously cleanse the site for 30 seconds and then allow it to air dry; do not use gauze to wipe off the site.  
  3. Once the puncture area is prepared, do not palpate the site again. If the puncture area is touched, it must be thoroughly prepped again.
