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

Calcofluor white, a fluorescent textile brightener, nonspecifically binds with chitin in the cell wall of fungi. Examination of stained specimens using fluorescent microscopy allows for the detection of fungi due to the fluorescence of calcofluor white present on the fungal cell wall. Potassium hydroxide is added to hasten clearing of viscous specimens, and Evans blue is added to prevent nonspecific fluorescence.(Snyder JW, Atlas RM, LaRocco MT: Reagents, stains, and media: Mycology.

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.

Monday through Sunday

Report Available The interval of time (receipt of sample at Mayo Clinic Laboratories to results available) taking into account standard setup days and weekends. The first day is the time that it typically takes for a result to be available. The last day is the time it might take, accounting for any necessary repeated testing.

1 to 2 days

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

Raw specimen saved 7 days

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