Lungworm Test for Dogs

Further information

Our Dog Lungworm Test provides extended laboratory screening for canine respiratory and nasal parasites using specialist faecal testing methods. To do this, our laboratory team examines faecal samples for relevant larvae and eggs associated with five parasite targets. As a result, this screening supports a test led approach to lungworm monitoring and helps you make informed decisions about your dog’s health.

What does the Dog Lungworm Test include?

Our extended lungworm screen covers the following parasites:

  • Angiostrongylus vasorum (French heartworm)
  • Crenosoma vulpis (Fox lungworm)
  • Oslerus osleri (Tracheal lungworm)
  • Filaroides hirthi (Pulmonary lungworm)
  • Eucoleus spp. (Respiratory and nasal capillarids)

Who is this test suitable for?

Lungworm screening can be particularly useful for dogs with increased exposure risks. For example, we recommend considering this test for:

  • Dogs that spend significant time outdoors, particularly in gardens, parks, woodland or countryside.
  • Dogs that may encounter or accidentally ingest slugs, snails or other potential sources of lungworm infection.
  • Dogs that scavenge, hunt or eat wildlife, including frogs or other small animals.
  • Dogs living in or regularly visiting areas where lungworm infections have been reported.
  • Dogs with a previous history of lungworm infection or those requiring ongoing monitoring as part of their parasite control programme.
  • Owners concerned about lungworm exposure who want a dedicated screening test.

How does the testing process work?

Each kit includes clear instructions and the materials needed to collect and return your dog’s faecal samples to our laboratory. Collect small faecal samples over three consecutive days. This is essential because parasite larvae and eggs may be shed intermittently. Therefore, samples collected over all three days are required for the lungworm screen. During collection, keep the lungworm samples in a cool place. Do not refrigerate or freeze them. Once your samples arrive, our trained laboratory team carries out the appropriate screening procedures. We then email your results on the next working day following arrival at our laboratory. In addition, every Dog Lungworm Test includes a clear laboratory report and free after-test advice where required.

Looking for gastrointestinal worm screening too?

If you would also like to screen for gastrointestinal worms, our Combined Worm Count and Lungworm Test for Dogs includes both screens in one convenient package. This provides broader parasite screening while keeping the sample collection process straightforward.

Canine Lungworm Screen

Our laboratory team uses two complementary testing techniques to provide a broader screening approach for lungworm and other respiratory parasites.

Parasites screened for include:

  • Angiostrongylus vasorum (French heartworm)
  • Crenosoma vulpis (Fox lungworm)
  • Oslerus osleri (Tracheal lungworm)
  • Filaroides hirthi (Pulmonary lungworm)
  • Eucoleus spp. (Respiratory and nasal capillarids)

Sample Collection

Collect faecal samples over three consecutive days. This is essential for reliable lungworm screening, as parasites may shed larvae or eggs intermittently rather than continuously. Collecting samples across three days increases the likelihood of detection and helps reduce the risk of a false-negative result.

Laboratory Reporting

Our trained laboratory team examines and reviews each sample before issuing clear, easy to understand results.

The test includes free after test advice where required.

We report whether lungworm larvae or relevant parasite eggs were detected in the submitted faecal sample.

Extended Lungworm Screen Results

Our extended canine lungworm screen uses specialist laboratory methods to look for respiratory and nasal parasites that may shed larvae or eggs in faeces. The screen includes:

  • Angiostrongylus vasorum (French heartworm)
  • Crenosoma vulpis (Fox lungworm)
  • Oslerus osleri (Tracheal lungworm)
  • Filaroides hirthi (Pulmonary lungworm)
  • Eucoleus spp. (Respiratory and nasal capillarids)

We report whether relevant larvae or eggs were detected and, where appropriate, identify the parasite and assess the findings.

Lungworm larvae and eggs may be shed intermittently. Faecal samples collected over three consecutive days are essential for this screening procedure.

Understanding Your Results

Every sample is carefully analysed by our trained laboratory team, with all results reviewed before your results are issued by email.

Your report clearly shows what we have tested for, whether any parasites were detected, and any relevant measurements. This helps you understand your results and make informed decisions about your animal’s parasite management, with free after test advice available whenever needed.

Turnaround time: We issue worm count results within 24 hours of the sample arriving at our laboratory. Please note: Laboratory testing is undertaken Monday to Friday, excluding bank holidays. Weekends and bank holidays are not included in our stated turnaround times.

Sample collection: Collect a fresh, representative faecal sample and follow the instructions supplied with your kit.

Results: We email your report once the laboratory examination and review are complete.

Your kit includes the materials needed to collect and return your faecal sample(s) to our laboratory:

  • A recyclable padded return envelope with prepaid Tracked 24 return postage.
  • Laboratory request forms and clear sample collection instructions.
  • Recyclable sample collection containers and resealable write-on bag(s).
  • Biodegradable secondary sealable bagS.
  • Biodegradable natural wood sampling spoon.

Each kit is for one dog. Please follow the sample collection instructions supplied.
