Submission and Collection Notes
The suspected organism may be included under the ‘Test Description’.
Please note on the requisition (under other): If the patient has Eosinophilia, HIV, is immunocompromised, has a critical illness or was admitted to ICU, or had a previous parasitic infection.
Indicate Country/Region and if the patient is a new immigrant or refugee or returned traveler under ‘Travel’ section of the requisition. It is imperative that the foreign country be identified.
Collect a sample in each white top and yellow top (SAF) vial of the Parasitology Kit. Follow the collection instructions on the instruction sheet provided with the Parasitology Kit.
Collect one specimen per day for 3 days in each vial for a total of six (6) specimens.
Limitations
Anti-diarrhoeal medication, radiological dyes (barium) and antibiotics interfere with the identification of intestinal protozoa as well as helminths and coccidians.
Storage and Transport
Place specimen container in a biohazard bag and seal. Reminder: Store the yellow capped container at room temperature at all times. The white capped container must be refrigerated before submission or frozen if there is a delay of more than 72 hours.
Special Instructions
Follow the instruction found in the updated Para Kit Instruction Sheet.
Collect faeces in clean dry container and immediately transfer a portion of the sample to the:
- White Cap sterile container and then emulsify another portion in the
- SAF preservative in the Yellow top container (Mix 1 part faeces with 3 parts SAF or 1 part liquid faeces with 1 part SAF).
The submission of the white top container will allow for method development of newer and more sensitive methods such as polymerase chain reaction (PCR) to obtain improved species identification.
Test Frequency and Turnaround Time (TAT)
Fasciola – Faeces specimen testing turnaround time is up to 5 days from receipt by the PHO laboratory.
Fasciola specimens are examined by microscopy for eggs following centrifugation procedure using the Formalin/Ethyl-Acetate Concentration Method. The concentration method allows for detection of small numbers of organisms.
Microscopy is used to identify eggs of Fasiola gigantica or Faciola hepatica.
