The Animal Health Trust (AHT) offers a biopsy (histology) service which includes examination of both surgical biopsies and post mortem samples, delivered by our experienced and approachable team of pathologists.
Our pathologists are all on-site and are always willing to discuss cases and offer advice on related matters such as appropriate sampling techniques. In difficult or challenging cases the final histology report will often reflect a ‘consensus opinion’, reached after examination by more than one pathologist.
We have a turn-around time of approximately 24-36 hours from receipt. In exceptional cases, such as large samples (that may need additional fixation prior to processing) and samples that require decalcification (including toes and bone biopsies) the turnaround time may be longer. We endeavour to keep you, the client, informed in all cases in which delay are expected.
In urgent cases suitable samples can also be reported on the day of receipt for a small additional fee (contact us and ask to speak to our histology laboratory for further details).
In addition to routine H&E staining normally used for histopathology, we also use a wide variety of special stains (including stains for copper accumulation in canine livers) to improve the accuracy of our diagnoses. These stains are done at the pathologists’ discretion, usually at no extra cost. However, if stains, such as the silver stains for fungi, is required (or requested by you) an additional charge may be incurred. We will NOT add any additional cost without prior consultation.
Biopsy samples should be submitted in 10% neutral buffered formalin in a non-glass leak-proof container. The ideal ratio between tissue and formalin should be 10:1, to insure adequate fixation. Especially in larger samples such as samples taken at post mortem/necropsy the thickness should ideally not exceed 10mm. Large samples should be partially incised through the superficial aspect to minimize distortion during fixation.
|The Animal Health Trust (AHT) is extremely grateful to the Horserace Betting Levy Board (HBLB), Racehorse Owners Association (ROA) and Thoroughbred Breeders’ Association (TBA) for their continued combined contribution to the AHT’s Equine Infectious Disease Service, which in particular supports key staff within the Diagnostic Laboratory and Pathology Service and allows enhanced investigation and control of significant equine infectious diseases in the United Kingdom.
