Organism Referred for Identification, Aerobic Bacteria
Identification of pure isolates of aerobic bacteria
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. All aerobically growing bacteria submitted will be identified and billed as appropriate.
Note: Mayo Medical Laboratories recommends referring suspect select agent isolates (eg, Bacillus anthracis, Brucella species, Burkholderia mallei, Burkholderia pseudomallei, Francisella tularensis, or Yersinia pestis) to your state health department or the CDC for identification confirmation or exclusion.
Clinical Information Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test
Organisms are referred to confirm identification or when the identity is unknown. This may provide helpful information regarding the significance of the organism, its role in the disease process, and its possible origin.
Techniques employed may include conventional biochemical analysis, commercial identification strips or panels, MALDI-TOF mass spectrometry or sequencing nucleic acid of the 16S ribosomal RNA (rRNA) gene.
Reference Values Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.
Identification of organism
Genus and species are reported on aerobic bacterial isolates, whenever possible.
Bacillus species will be reported out as "Large spore-forming aerobic gram-positive Bacillus, not Bacillus cereus or Bacillus anthracis," unless species identification is specifically requested on the request form.
Cautions Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances
Isolates suspected of being select agent isolates (eg, Bacillus anthracis, Brucella species, Burkholderia mallei, Burkholderia pseudomallei, Francisella tularensis, or Yersinia pestis) should be submitted to client’s state health department or the CDC for identification confirmation or exclusion.
