Describes how the test is performed and provides a method-specific reference
Specimens are plated on mycobiotic agar, which contains chloramphenicol and cyclohexamide to inhibit bacterial and saprobic fungal contamination. Cultures are incubated at 30 degrees C for 30 days. Identification of dermatophyte species is based on colony and microscopic morphology and polymerase chain-reaction (PCR), DNA sequencing or matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry, when applicable.(Hall L, Wohlfiel S, Roberts GD: Experience with the MicroSeq D2 large-subunit ribosomal DNA sequencing kit for identification of filamentous fungi encountered in the clinical laboratory.

Day(s) Performed
Outlines the days the test is performed. This field reflects the day that the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time before the test is performed. Some tests are listed as continuously performed, which means that assays are performed multiple times during the day.
