Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.

When this test is ordered, Anaerobe Suscep Battery will be performed at an additional charge. All bacterial organisms submitted will automatically have susceptibility testing performed and billed as appropriate. Antimicrobial agents appropriate to the organism and specimen source will be chosen from the panels listed below.


The following antimicrobials are routinely tested for the various groups of anaerobes: 

Anaerobic gram-negative bacilli

Beta-lactamase positive

Piperacillin/tazobactam, ertapenem, metronidazole, clindamycin

Anaerobic gram-negative bacilli

Beta-lactamase negative

Penicillin, clindamycin, metronidazole

Anaerobic cocci and nonspore-forming gram-positive bacilli, Clostridium perfringens

Penicillin, clindamycin, metronidazole

Clostridium species other than Clostridium perfringens

Penicillin, clindamycin, metronidazole, ertapenem, piperacillin/tazobactam

Propionibacterium species

Penicillin, moxifloxacin, minocycline

Actinomyces species

Penicillin, clindamycin

For antimicrobial agents not part of above panels: testing is available upon special request at an additional charge per antimicrobial: Amoxicillin/clavulanic acid, ceftriaxone, meropenem, ciprofloxacin, and vancomycin.

Note: Amoxicillin/clavulanic acid is only prepared Monday through Friday.


If fewer than 3 antibiotics will be reported, then Anaerobe Suscep Battery will be canceled and Anaerobe Suscep per agent will be charged per antibiotic.


Based on susceptibility criteria, Beta Lactamase and/or Anaerobe Suscep per agent may be performed at an additional charge.
