Understanding My EFEC Results

Updated: Jan 3

How to understand your results from EFEC Nutrition?

Faecal Worm Egg Counts

  • Once your horses' sample has been tested results will be emailed to the email address provided on your horse sample information form.

  • The email will outline the parasitic burden identified (if applicable) and provide you with recommendations for suitable treatment, based on your horses' information.

  • Further recommendations will also be included such as when to next provide a faecal worm egg count, if a reduction test is recommended and management practices to help support your targeted worming programme.

What do the results mean?

  • <200epg - This is considered a low burden and no treatment is required.

  • 225epg- 1,500epg - A moderate to high burden and treatment is required.

  • >1,500epg - A high burden, treatment is required and sometimes veterinary referral will be recommended.

Equisal Test

  • After posting your Equisal sample it will be processed in the Austin Biologist lab and the results will be emailed to EFEC Nutrition.

  • These results will be emailed over to you with treatment recommendations (if required) and when the test is recommended.

What do the results mean?

  • * An indeterminate result means that we have been unable to obtain a result for this horse's sample during today's testing. There are a number of reasons why this happens; a) the sample was too dilute to obtain a reliable result, in this case we are able to concentrate the sample and retest on the next test day; b) the scientific data for the sample was inconclusive and needs repeating on our next testing day. Apologies for the inconvenience but we ensure that each result is reported accurately by following this quality control procedure.

  • ** This sample was too dilute to obtain a reliable result and it has not been possible to concentrate it. Please could you issue another kit (we will credit you for this on your next order) and emphasise the sampling instructions i.e. wait for 30 mins after feeding/exercise before sampling. This is very important to obtain a reliable result. It may be that the horse is naturally slobbery, but we think that resampling this horse would be a good place to start.

  • *** This sample generated results that were off scale in one of the tests and, as a result, the saliva score is likely to be higher than reported. This horse has been diagnosed as having a moderate/high burden and therefore worming for tapeworm is recommended.


The results provided will identify horses with a low burden, a borderline result or a moderate/high burden and treatment is recommended by Austin Davis Biologics as detailed in the table below.
