Ten days after presentation, she developed Pneumocystis carinii pneumonia which was confirmed by identification of the organism in bronchial lavage specimens.

These results agree with those recently presented of tests that examined bronchial lavage fluid, in which half of patients with sarcoidosis were positive for M tuberculosis DNA.

Epi proLung - a test to measure the methylation status of the SHOX2 gene in bronchial lavage fluid, to help in the workup of patients suspect to have lung cancer.

Other examples of specimen requiring amplification for genome-wide characterization of gene expression include purified populations of cells obtained by either flow cytometry, laser capture microdissection, breast ductal or bronchial lavage, or microendoscopy.
