Collection Offsite

Swab skin over the site of venipuncture with iodoform solution for 1 minute in a 2 inch circular area around vein to be used, using vigorous strokes and working from the center to the periphery. Allow to dry 2 minutes before performing venipuncture. If use of 2% iodine preparation is contraindicated in patients sensitive to iodine, alcohol alone may be used. DO NOT palpitate venipuncture site after preparation. Draw blood into BacTec Myco/F Lytic Culture Vial. Do not refrigerate or incubate. For optimum recovery, send directly to the laboratory. Label bottle with patient's name, registration number, and culture number or anatomic site if more than one culture is drawn at one time. Indicate specimen source, collection date/time, current antibiotic or antifungal therapy, and clinical diagnosis. If unacceptable specimen is received, the client will be notified before disposal of the original specimen.
