Test 9221 :
Organism Referred for Identification, Aerobic Bacteria

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, carbon source utilization, and sequencing nucleic acid of the 16S ribosomal RNA (rRNA) gene.

Useful For Suggests clinical disorders or settings where the test may be helpful

Identification of pure isolates of aerobic bacteria

Interpretation Provides information to assist in interpretation of the test results

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 speciation is noted or 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 Bacillus anthracis should be submitted to client's state health department for testing.

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.
