Faecal Amoeba Stain

Faecal amoeba stains are used when Dientamoeba fragilis is suspected and no other pathogens causing prolonged diarrhoea or weight loss can be found.

Collection of the specimen

  1. Collect a faecal specimen in toilet paper or a clean container, such as a disposable plate. Urine must not be mixed with faeces. A specimen collected from the toilet bowl may not be used.
  2. Use the spoon in the collection container lid to place some faeces in the container with liquid until the level of liquid in the container rises to the red line. Close the cap carefully.
  3. Mix the faecal specimen with the liquid in the collection container until it forms a smooth paste.
  4. Write your name, date of birth and specimen collection date on the label and affix it to the container. If several specimens were requested, collect them on different days.
  5. Bring the container to the laboratory as soon as possible after collecting the specimen, no later than the following morning. The specimen must be stored in a cool place, such as the refrigerator.
  6. Fill in the details below and bring them to the laboratory with the sample.
