NoteAdditional information related to the test.
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.
