Clinical Pathology

The clinical pathology laboratory at the Animal Health Trust is staffed by a boarded clinical pathologist and four technicians.

We have a high-quality laboratory equipped with state-of-the-art analysers; with some of our tests accredited to ISO17025.

We provide a wide range of diagnostic tests and services including haematology, clinical chemistry, serology, endocrinology, cytology, microbiology and parasitology. A clinical pathologist is always available for consultation, helping veterinarians in the interpretation of the results.

Our blood cell counts are performed using an Advia 120 Automated Haematology Analyser. Unlike most other veterinary laboratories, blood film examination is performed manually on all the samples in order to confirm the results of the analyser, making possible the identification of any morphological change that might be missed by the automated analysers.

Special attention is reserved for lymphoproliferative disorders where blood film and bone marrow examinations are crucial for a proper identification and classification.


A wide variety of clinical chemistry tests are offered by our laboratory and are performed on a Konelab 20i random access analyser. These tests are extremely useful in order to diagnose diseases, monitor disease progression or response to therapy.

Our clinical pathology laboratory offers several chemistry panels for both small animals and equine; these panels include routine panels (routine and comprehensive panels) and variants thereof (e.g. liver and renal panels). A direct telephone contact with our clinical pathologist to discuss cases is also available and written interpretation/comments on the tests performed can be requested by ticking the appropriate box on the submission form.

We are also happy to send samples away to various other laboratories on request, for endocrine assays, etc.


We offer a basic coagulation screen to investigate both sides of the coagulation cascade; although further information can be obtained from our full coagulation profile which includes basic haematology with specific focus on platelets and a thrombin clot time to examine the final stage of fibrin formation. We also have assays to identify specific clotting factor deficiencies. We use semi-automated methods which tend not prone to some of the problems seen with fully automated analysers; this also allows us to examine the integrity of the clots formed.

We also offer canine von Willebrands factor antigen testing via Cornell University, New York.
