Clinical Notes must include: travel history, +/or chronic diarrhoea (include duration), +/or weight loss +/or eosinophilia, +/or overseas adoption +/or immunosuppression when requesting parasite investigation. Otherwise only direct wet-preparation will be performed.

When the index of suspicion is high and when the organisms are not found in stool, duodenal contents should be examined.  Strongyloides serology should also be performed. 

2 x stool specimens collected within any 7 day period should be submitted in faecal containers. 

For each collection, send faeces in a sterile container and a 1/2 teaspoon of faeces in the SAF fixative and shake to emulsify. 

Duodenal contents may be collected using the Enterotest system.

This test can be added up to 5 days from collection.
