Antimicrobial Susceptibility, Nocardia species
Method Description Describes how the test is performed and provides a method-specific reference
A standardized inoculum made from a pure culture of aerobic actinomycete is prepared and inoculated into wells of a microtiter plate containing different concentrations of 13 antimicrobial agents. These include trimethoprim/ sulfamethoxazole, linezolid, ciprofloxacin, imipenem, moxifloxacin, cefepime, augmentin, amikacin, ceftriaxone, doxycycline, minocycline, tobramycin, and clarithromycin.
Growth at specified breakpoints is indicative of resistance.(Wallace RJ Jr, Steele LC: Susceptibility testing of Nocardia species for the clinical laboratory.

Day(s) and Time(s) Test Performed Outlines the days and times the test is performed. This field reflects the day and time the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time required before the test is performed. Some tests are listed as continuously performed, which means assays are performed several times during the day.
One or two times per week; NA
Analytic Time Defines the amount of time it takes the laboratory to setup and perform the test. This is defined in number of days. The shortest interval of time expressed is "same day/1 day," which means the results may be available the same day that the sample is received in the testing laboratory. One day means results are available 1 day after the sample is received in the laboratory.
Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Medical Laboratories until the release of the test result
Performing Laboratory Location The location of the laboratory that performs the test
