Cystic Fibrosis (CF) Lower Respiratory Culture
Collect: Sputum, endotracheal aspirate, bronchoalveolar lavage (BAL), bronchial brushing, transbronchial biopsy, deep pharyngeal swab - 5-10 mL sputum, 10-50 mL lavage fluid, 5 mL bronchial washing, one swab
Sputum: The patient should brush his/her teeth and/or rinse mouth well with water before attempting to collect the specimen, in order to reduce the possibility of contaminating the specimen with food particles, oropharyngeal secretions, etc. Instruct the patient that only a specimen brought forth by deep cough should be expectorated into the container. After the specimen has been collected, it should be examined to make sure it contains a sufficient quantity (at least 1 mL) of thick mucus (not saliva). Only the sterile screw-cap container should be submitted to the laboratory.
Deep pharyngeal swab (cough or gagged throat specimen): Place a plastic shaft polyester- or rayon-tipped swab in the back of the throat and induce coughing. Remove the swab when coughed secretions have been collected on the swab. Place swab in plastic transport sleeve containing preservative medium and submit to the laboratory. Note: This technique is used in those CF patients who are unable to produce sputum.
Storage/Transport Temperature: Refrigerate
Note: This test is approved for NY .
