What is a reasonable target for a zone 3 swab at preop ? We are looking at <100 cfu sq in for Zones 1 and 2 but not sure if this is a reasonable specification for Zone 3. Can I get some input ?
They just recently expanded to include Zone 3 - so I have no history. I also need to know any reference material that I might use as justification to expand this target number.
Thank you for any direction you can give me !
