Test ID: CFRC    
Bacterial Culture, Cystic Fibrosis, Respiratory

Method Description Describes how the test is performed and provides a method-specific reference

Standard media (5% sheep blood, chocolate, and eosin methylene blue [EMB] agar plates) used for respiratory cultures are inoculated. In addition, 2 selective agar plates are utilized to enable isolation of slower growing pathogens that may be easily overgrown by usual flora and the longstanding colonization by Pseudomonas aeruginosa. Burkholderia Cepacia Selective Agar plate is used for the isolation of Burkholderia cepacia complex, which includes 9 distinct species. Isolates of Burkholderia cepacia will be forwarded to the University of Michigan's CFF Research Testing and Repository for genotyping. (There is no charge for this shipping/testing). A chromogenic Staphylococcus aureus agar is used to enhance the isolation of Staphylococcus aureus. Finally, a second chocolate blood agar plate is incubated in an anaerobic atmosphere. The anaerobic atmosphere allows for detection of Haemophilus species that may otherwise be overgrown by Pseudomonas aeruginosa.(Gilligan P: Section 3: Respiratory cultures from cystic fibrosis patients.

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.

Monday through Sunday; Continuously

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.

5 days

Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Medical Laboratories until the release of the test result

12 days

Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded

1 day

Performing Laboratory Location The location of the laboratory that performs the test

Rochester
