* Reference ranges may change over time. Please refer to the original patient report when evaluating results.

Specimen Requirements

Collection Offsite

The patient should be instructed to remove dentures, rinse mouth with water and cough deeply, expectorating sputum into the sputum collection cup. First morning sputum, first morning gastric aspirate, induced sputum, aspirated sputum, bronchial aspirate, tracheal aspirate, transtracheal aspirate, or endotracheal aspirate are acceptable specimens. If Histoplasma or other fungal species is suspected, indicate on requisition. For optimum recovery, send directly to the 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 therapy, and clinical diagnosis. Do not submit more than four specimens in one 7 day period unless by prior arrangement. If an unacceptable specimen is received, the client will be notified and another specimen will be requested before disposal of the specimen.
