Horse Worm Count Reduction test after worming


Worm egg count kit to test to do after worming for resistance to redworm and roundworm in equines, including horses, ponies, donkeys and mules.

Does your horse have resistant worms? Following a positive redworm or roundworm count that has required worming treatment or a winter worming dose for the possibility of encysted redworm, a second worm egg count can be conducted, ideally 10-14 days after treatment to test for drug efficacy. To take advantage of this special offer customers must include the box end of the wormer with the batch code with the faecal sample.


Test kit includes everything you need to take and send a sample including pre-paid voucher(s) for laboratory testing.

Kit price includes:

  • a pot to collect a faecal sample for each horse
  • a voucher for the laboratory processing of the tests
  • a compostable glove (if we have supply)
  • one pre-paid envelope to send the sample(s) to the lab

Test price includes veterinary approved worming advice from our friendly team of qualified SQP's if required. Please phone, email or contact us on our Facebook page. 

£7 per horse, one box end per test please.


If this test is used in any other way than after treatment then an additional fee will occur.

I have a tricky horse, he can have a worm burden even when his fellow herd mates do not so I have to keep an eye on this with regular checks. I have used Westgate Labs worm counts for many years now and thankfully as a result of their reliable, efficient service we are on top of the situation. 

Thank you Westgate Labs, much appreciated.
