Test Details

Use

This test is used to determine the presence of Pneumocystis jirovecii pneumonia (PJP) (formerly Pneumocystis carinii).

Methodology

Gomori methenamine silver stain and microscopic evaluation are performed.

Additional Information

The Cytology laboratory does not offer a Pneumocystis stain by itself but does offer a cytologic interpretation of the specimen in conjunction with a special stain for PJP. This policy assures that the specimen is adequate (i.e., if pulmonary macrophages are present in a sputum), as well as review for atypical or malignant cells. If only a special stain for PJP is wanted, without cytologic review of the cells, please order Test No. 180232 to be sent to the microbiology department.
