  • Parasite identification
  • Wet prep exam
  • Baermann for lungworm
  • Quantitative faecal examination
  • Total worm counts of the gastrointestinal tract (GI) or GI washings

2 Pooled or individual samples accepted, although individual samples are preferred.
3 Larval differentiation is performed if the faecal egg count is > 100 eggs per gram. Results are presented as % Trichostrongylus, Ostertagia and Haemonchus. This test must be specifically requested on the submission form if required.

Specimen requirements

Faeces

  • Faeces from each animal collected into separate sterile containers as per below:
    • 5 grams from each animal if pooling samples
    • 10 grams from each animal if testing individual animals
    • 10 grams from each animal if requesting export liver fluke testing to Western Australia
    • 15 grams from each animal if requesting export testing to New Zealand
  • The use of a WormTest kit for collection is recommended for flock or herd testing
  • Refer to the sample collection guide for additional information on sample collection for faecal egg count (worm testing), or faecal egg count reduction (drench test).

Fresh tissue

  • Abomasum, large intestine, small intestine or intestinal contents
    • Submit chilled

Parasite or snail

  • Whole parasite or snail
    • Submit chilled or fixed in neutral buffered formalin at a 10:1 ratio of 10:1 formalin: tissue

Scraping

WormTest Kits

WormTest Kits provided by rural suppliers and from NSW DPI on request. They can be used as a simple and quick way to monitor your worm control program by checking drench effectiveness through standard faecal egg counts and are available for horse and livestock. They contain an information sheet, collection instructions, prepaid postage to the laboratory, a mailing container, a glove and ten sample containers. Two options are available:

  • Worm test (faecal egg count) – Pooled (2 pools of 5 samples)
    • This test is offered for up to ten animals and samples are pooled in the lab into two worm tests. This is a cost effective way to monitor your herd’s health and drenching needs. A minimum of 5 grams of faeces per animal is required.
  • Worm test (faecal egg count) – Individual (10 individual samples)
    • This test is offered for up to ten animals and each sample is tested and reported individually. Animals that are housed separately should be tested individually. Using this test you can benefit from the cost savings by submitting up to ten animals’ samples together from multiple sites. A minimum of 10 grams of faeces per animal is required.
