Test ID: FUNID    
Culture Referred for Identification, Fungus

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

Identification of fungi is based on colonial and microscopic morphology, a variety of physiologic or biochemical tests, nucleic acid hybridization probe tests, PCR or DNA sequencing when applicable. Nucleic acid probes are used for Histoplasma capsulatum and Blastomyces dermatitidis. Real-time PCR is used to assist with identification of Coccidioides species. D2 DNA sequencing used to assist with identification dermatophytes and nonsporulating fungi.(Binnicker MJ, Buckwalter SP, Eisberner JJ: Detection of Coccidioides species in clinical specimens by real-time PCR. J Clin Microbiol 2007;45:173-178; Hall L, Wohlfiel SL, Roberts GD: Experience with the MicroSeq D2 large-subunit ribosomal DNA sequencing kit for identification of filamentous fungi encountered in the clinical laboratory. J Clin Microbiol 2004;42:622-626)

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 Saturday; Varies

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.

2-35 days: If organism is received in mixed culture or is contaminated, report

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

35 days

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

30 days after identification

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

Rochester
