Specimen Requirements
Collect liver aspirate or drainage, cyst drainage, or duodenal aspirate specimen following sterile preparation of aspiration site. DO NOT ASPIRATE POSSIBLE ECHINOCOCCAL CYST as leakage may cause anaphylactic shock. Specimens to rule out Echinococcus should be handled carefully as the organism is highly infectious. If Entamoeba histolytica is suspected, send the last part of the aspirate. Put actual specimen, not saline washings, into the O&P transport vial and emulsify specimen well. Transports may be refrigerated or kept at room temperature for up to 1 week. Sputum exam is done by special request; please contact the MLabs Client Services Center before sending fresh sputum. Fresh specimens should be kept at room temperature and sent to the laboratory within 30 minutes of collection. Indicate specific parasite that is suspected, specimen source, and collection date/time. If an unacceptable specimen is received, the client will be notified before disposal of the original specimen.
