Specimen Requirements

Offsite Collection Instructions

Collect specimen using standard bronchoscopy procedure. Acceptable specimen types include bronchial aspirate, bronchoalveolar lavage, tracheal aspirate, transtracheal aspirate, leukens, and induced sputum. Do not incubate. For optimum recovery, send directly to MLabs. If specimen must be stored and Histoplasma isolation is not desired, refrigerate immediately after specimen collection. May be refrigerated up to 24 hrs. If Histoplasma isolation is desired, keep specimen at room temperature and send within 4 hrs of specimen collection. Specify specimen source, collection date/time, current antibiotic or antifungal therapy, and clinical diagnosis. If an unacceptable specimen is received, the client will be notified before disposal of the original specimen.
