Test ID: SPN    
Pneumocystis Smear

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

A rapid Calcofluor white stain is used to detect the cysts of Pneumocystis jiroveci (formerly carinii). Calcofluor white is a nonspecific fluorochrome stain that binds with beta-configuration polysaccharides such as cellulose and chitin. Only the cyst stage of Pneumocystis jiroveci (formerly carinii ) stains by this method. Both the 2 internal structures and cyst wall must be seen before calling the slide positive for Pneumocystis jiroveci.

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.

1 day

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

1 day

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

Raw specimen 2-14 days

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

Rochester
