Use for rapid identification of P. jirovecii. Negative DFA results are confirmed by PCR testing. Sensitivity is dependent on patient population and specimen type.
Direct Fluorescent Antibody Stain/Qualitative Polymerase Chain Reaction
Respiratory specimen: Bronchial washing, bronchoalveolar lavage (BAL), or induced sputum.
Transfer 5 mL respiratory specimen to a sterile container. (Min: 1 mL) Place each specimen in an individually sealed bag.
Tissues. Formalinized specimens. Slides or swabs.
Specimen source required.
Ambient: 2 hours; Refrigerated: 1 week; Frozen: Unacceptable
A negative stain result does not exclude the possibility of infection. False-negative results may occur due to sampling errors or a low number of organisms in the specimen. If Pneumocystis jirovecii DFA is negative, then Pneumocystis jirovecii by PCR testing will be added. Additional charges apply.
