What are the turnaround times for microbiology tests?

Please remember that organisms need time to grow and that the general workflow for microbial culture & sensitivity is:

Specimen receipt > sample inoculated onto plates > overnight incubation > review of culture plates to assess for growth & ID of any organisms > Interim report issued with organism ID > sensitivities set-up for organism(s) + overnight incubation > review of susceptibility results > final report with sensitivities (at least 48h after receipt of specimen).

Where can I find secondary care antimicrobial guidelines?
