Specimen Requirements
Collection Instructions

Collect body fluid, pleural fluid, peritoneal fluid, pericardial fluid, synovial fluid, ascitic fluid, or thoracentesis fluid in a sterile container. Do not refrigerate or incubate. For optimum recovery, send directly to MLabs. If Histoplasma isolation is desired, keep specimen at room temperature and send to MLabs within 4 hrs of specimen collection. If specimen must be stored and Histoplasma isolation is not desired, refrigerate immediately after specimen collection. May be refrigerated up to 24 hrs. Specimen Collection: Cleanse area with soap solution, remove soap with 70% ethanol. Apply 1% tincture of iodine. Iodine must remain on skin 2-4 minutes for maximum effectiveness. Remove with 70% alcohol. If patient is allergic to iodine, alcohol alone can be used. DO NOT TOUCH prepared skin during collection of specimen.

Normal Volume
0.5-50 ml fluid; DO NOT SEND SWABS
Minimum Volume
0.5-50 ml fluid; DO NOT SEND SWABS
Additional Information

Test includes culture and, if specimen is adequate, direct smear. Isolation of Histoplasma is suboptimal from specimens older than 4 hrs and is unlikely from specimens older than 8 hrs.
