Samples should be collected following these guidelines:

Faeces from each animal should be collected into separate containers as outlined below

1. Amount:

Note: It is recommended to fill each of the sample containers. If this is not possible then minimum requirements from each animal are as follows:

  • Individual WEC ~ 10g
  • Pooled WEC ~ 5g
  • Liver Fluke Test ~ 10g

Note: 5 grams of dung in volume measurement is approximately:


  • Dry Pelleted Faeces:5 pellets (Adults); 7 pellets (lambs)
  • Moist Faeces: 1 level teaspoon. 


  • Take 2-3 small ‘grabs’ from each dung pile i.e. one dung pile per animal. Ensure all samples are an equal from each of the samples collected and place all of the containers into the specimen transport bag provided. The samples will be pooled at the laboratory accordingly to the completed test acquisition form.

2. Method

The collection method chosen is determined by the test required. Samples can be collected from freshly deposited dung samples or from the rectum of individual animals. Gloved fingers or forceps may be used to assist collection and deposition into collection tubes.

Pooled Worm Egg Counts

Collect 15 individual faecal samples directly from freshly yarded animals (e.g. have been in yards < 4hrs). Select animals randomly.  Collect approximately 5grams per animal

When using the 15 sample tubes provided in the test kit, the laboratory will combine dung from five animals and thus provide three counts per 15 dung samples. The laboratory determines the average of the three counts.


Muster a large number of the mob, or herd to a clean corner of a paddock for 10 minutes and then let them drift away quietly. Fresh, clean dung samples can then be collected from the ground, avoiding soil. Samples must be fresh. Fresh samples will be warm

Individual Worm Egg Counts

If you are not able to collect a freshly deposited dung sample (10 grams)  then samples may be collected from the rectum of each animal. Run freshly yarded animals into a race and collect approximately 10grams of faeces per animal.

For any individuals which prove difficult to obtain a sample from, set them aside and try again in 15mins.

Place sample into an individual collecting tube.  Label each sample with the animal’s ear tag or reference number.

If you would like to relate the egg count back to the individual animal then label the containers 1 to 15 and keep a record of the animal identification corresponding to the number.

If using zip-lock bag, ensure you squeeze as much air out of the bag as possible.

If ‘larval type’ is requested (that is larval culture and differentiation), dung is pooled from the 15 animals to determine the type of worms present in the mob.


  • Mixing Ewe and Lamb samples
  • Mixing different ages e.g lambs/weaners/adults
  • Soil
  • Very weak or ill sheep
  • Sheep yarded more than 4-6 hrs

3. Timing

Avoid hot weather.  Start collecting samples early in the morning if possible. Use an esky to place samples into on hot days when there are a large number of samples collected.

  • Collect samples at a time that they can be promptly delivered to our laboratory or, if posted, will not be delayed in the post over a weekend.

Complete the Test Acquistion form and packaging as per the instructions provided

4. Packaging/Post

Once you have completed the collection and the accompanying test acquisition form, place samples into the specimen transport bag, then the mailing box and express post parcel satchel.  (Note the absorbent sheet is required to remain within the specimen transport bag with the samples). Your satchel can then be placed into any yellow express post box or delivered directly to the counter at any Australian Postal Shop. Postage is paid if a test kit is pre-purchased.

5. Results

Results are normally sent via email but can be sent by text message if you prefer. Select the relevant option when completing your submission form.

Results are emailed within 24hrs of sample arrival in the lab. Those mobs that require urgent results please mark accordingly so that they get priority. Preferably phone to make arrangements to ensure there are no delays.

NB.Scopex Laboratories strongly recommend that you consult a veterinarian, or other suitably qualified adviser, for advice on monitoring and interpretation of the results
