Clinical Utility

Pneumocystis jiroveci (formerly known as Pneumocystis carinii) pneumonia is a major cause of illness and death in individuals with impaired immune systems. Pneumocystis almost always affects the lungs, causing a form of pneumonia referred to as PCP. The organism that causes PCP has been renamed Pneumocystis jiroveci to reflect its new classification as a fungus. Quantitative DNA PCR is useful to detect the organism, track the course of infection, and monitor response to treatment.

Procedure

Extraction of Pneumocystis jiroveci DNA from specimen followed by amplification and detection using real-time, quantitative PCR. An internal control is added to ensure the extraction was performed correctly and the PCR reaction was not inhibited. This test has not been cleared or approved for diagnostic use by the U.S. Food and Drug Administration.

Specificity

The primers and probes used in this assay are specific for known Pneumocystis jiroveci strains based on similarity search algorithms. Additionally, no cross reactivity was detected with any viral or protozoa pathogens.

Same day (within 8 - 12 hours from receipt of specimen), Monday through Saturday.
