When your sample reaches our laboratory it is examined under the microscope and the result is added to your account within 24 to 48 hours of the lab receiving it. We email you when it is ready.
What does the report show?
The report lists which types of eggs or oocysts were seen in your sample. The standard livestock worm count reports roundworm (strongyle) eggs, Nematodirus, tapeworm, and coccidial oocysts. Other eggs, such as whipworm or pig roundworm, are reported when seen.
Egg counts are a guide, not a rule
There is no single egg count that applies to every animal. What counts as high depends on the species, the age of the animal, the season, the type of worm and whether animals are growing and healthy. Roundworm eggs are reported as eggs per gram (e.p.g.) where a count is made. As a guide, young stock and animals in poor condition matter most, while healthy adults with good immunity can carry lower counts without harm. Talk to your vet or animal medicines adviser about what a result means for your animals.
Group samples
A sample usually covers a group of animals of the same species and age on the same ground, so the result shows what the group is carrying, not each animal. Sampling several animals gives a more reliable picture than a single dropping.
Coccidia results
Coccidia are reported as none, low, moderate or high. A few oocysts are normal in young animals. A high result matters more if lambs, kids, calves or piglets are scouring or growing slowly, so speak to your vet.
What does it mean if no eggs are seen?
That is good news, but it is a snapshot. Worms shed eggs intermittently, and very young animals or animals with immature worms may not yet be shedding. A clear result does not guarantee animals are worm-free, and testing again gives a better picture over time.
Checking that a wormer has worked
A follow-up test 7 to 14 days after treatment, depending on the wormer used, shows whether the egg count has fallen as it should. A poor drop can mean the worms are resistant to that wormer. Wormer resistance is widespread in sheep and goat worms, so checking is worthwhile. Always follow the label for dose and withdrawal times.
Ready to test?
Collect fresh faeces at home, post them free to our laboratory (Monday to Wednesday) and your result appears in your account within 24 to 48 hours of the lab receiving your sample.
