- parasite identification
- wet prep exam
- Baermann for lungworm
- quantitative faecal examination
- total worm counts of the gastrointestinal tract (GI) or GI washings

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) – Basic (2 pooled 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) – Gold (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.
