Alverno Laboratories is instituting a procedure change for Blood Culture collection to align with Clinical and Laboratory Standards Institute (CLSI) recommendations regarding the timing of specimen collections for Blood Culture. If more than one Blood Culture is ordered concurrently by the provider, please ensure that: Both sets of Blood Cultures are drawn at the same time from two separate venipunctures performed at two different anatomical sites, using two separate needles. Do NOT collect two sets of Blood Cultures from one venipuncture.
