Test Code CFRC Bacterial Culture, Cystic Fibrosis, Respiratory

Performing Laboratory

Mayo Clinic Laboratories in Rochester

Useful For

Detection of aerobic bacterial pathogens from cystic fibrosis patient specimens

Testing Algorithm

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

Method Name

Conventional Culture Technique

Reporting Name

Bacterial Culture, Cystic Fibrosis

Specimen Type

Varies


Advisory Information


If susceptibilities are desired when this test is ordered, also order ZMMLS / Antimicrobial Susceptibility, Aerobic Bacteria, MIC. Each pathogen isolated will then be tested with the appropriate susceptibility panel. Charges are added for each susceptibility test performed.



Shipping Instructions


Specimen must arrive within 48 hours of collection.

Reference Values

No growth or usual flora

Identification of probable pathogens

Interpretation

A negative test result is no growth of bacteria or growth of only usual flora. A negative result does not rule out all causes of infectious lung disease (see Cautions).

 

Organisms associated with lower respiratory tract infections are reported.

 

For positive test results, pathogenic bacteria are identified. Cystic fibrosis patients may be colonized or chronically infected by some organisms over a long period of time, therefore, positive results must be interpreted in conjunction with previous findings and the clinical picture to appropriately evaluate results.
