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

When this test is ordered, the reflex tests may be performed and charged separately.

Antimicrobial agent appropriate to the organism and specimen source will be chosen from the panels listed below.

Note: Mayo Medical Laboratories will not perform susceptibility testing on select agents (eg, Bacillus anthracis, Brucella species, Burkholderia mallei, Burkholderia pseudomallei, Francisella tularensis, and Yersinia pestis). Please consult with your state health department or the CDC regarding antimicrobial susceptibility testing of such isolates.

 

Gram-negative bacillus: amikacin, ampicillin, ampicillin/sulbactam, cefazolin, cefdinir, cefepime, ceftazidime, ceftriaxone, ciprofloxacin, ertapenem, fosfomycin, gentamicin, levofloxacin, meropenem, nitrofurantoin, piperacillin/tazobactam, ticarcillin/clavulanic acid, tobramycin, and trimethoprim/sulfamethoxazole (TMP/SMX). The 2011 Clinical and Laboratory Standards Institute (CLSI) breakpoints for cephalosporins and carbapenems have been implemented. Confirmation testing for extended spectrum beta-lactamases is performed on Escherichia coli, Klebsiella species, and Proteus mirabilis isolates by request. Klebsiella pneumoniae carbapenemase (KPC)/New Dehli-metallo-beta-lactamase (NDM) molecular testing, modified Hodge testing, and/or Carbapenemase-Carba NP Test are available for individual order.

 

Staphylococcus species: ceftaroline (methicillin-resistant Staphylococcus aureus: MRSA only), clindamycin, levofloxacin, linezolid, minocycline, mupirocin, nitrofurantoin, oxacillin, rifampin, TMP/SMX, and vancomycin. D-test is performed on all isolates for detection of clindamycin resistance.

 

Enterococcus species: gentamicin synergy, levofloxacin, linezolid, nitrofurantoin, penicillin, and vancomycin

 

Streptococcus species: cefepime, ceftriaxone, erythromycin, levofloxacin, meropenem, penicillin, tetracycline, TMP/SMX, and vancomycin

 

Haemophilus species: ampicillin if beta-lactamase negative

 

Neisseria gonorrhoeae: cefixime, ceftriaxone ciprofloxacin, tetracycline

 

Helicobacter pylori: amoxicillin, ciprofloxacin, clarithromycin, metronidazole, tetracycline

 

For antimicrobial agents not part of above panels: testing is available upon special request at an additional charge per antimicrobial (eg, colistin, daptomycin, tigecycline).
