Review highlights pathology technicians’ role in veterinary medicine
Bottom line
A new review in Animals argues that pathology technicians are an underrecognized but essential part of veterinary diagnostics, research, and teaching, with responsibilities that directly affect specimen quality, turnaround times, and the reliability of pathology results. The paper, by Diana Araújo, Fátima Carvalho, and Nuno Vale, makes the case that anatomical pathology depends not only on pathologists, but also on the technical professionals who collect, process, section, stain, and manage tissue samples before a slide ever reaches a microscope. That framing aligns with broader veterinary pathology guidance from the American College of Veterinary Pathologists, which describes pathology as central to disease diagnosis and drug development, and with laboratory standards from the American Association of Veterinary Laboratory Diagnosticians that explicitly include histotechnology among core technical staffing needs.

Why it matters: For veterinary professionals, the review is a reminder that diagnostic quality starts well before interpretation. Histology and pathology technicians handle the preanalytic and analytic steps that can determine whether a biopsy, necropsy, or research specimen yields a clear answer, and accredited veterinary diagnostic lab standards recognize those roles as part of the workforce required to run pathology services. In a period of broader veterinary workforce strain, the paper also lands amid ongoing concern about specialist and technical pipeline gaps, including longstanding shortages in pathology and persistent recruiting and retention pressure across technician-facing roles.

What to watch: Expect more attention on training pathways, role recognition, and digital pathology tools that could reshape how pathology technicians support veterinary diagnostics, research, and teaching. (labcorp.com)
A review published in Animals is putting a spotlight on a part of veterinary medicine that often stays behind the scenes: pathology technicians. In “The Critical Contribution of Pathology Technicians to Veterinary Diagnostics, Research and Teaching,” the authors argue that these professionals are foundational to the quality and consistency of veterinary pathology, even though public and professional attention tends to focus more heavily on pathologists themselves. The paper’s central point is straightforward: without skilled technical work in specimen handling and histology, diagnostic pathology can’t function reliably. (vhwda.org)
That message lands in a field where pathology already carries outsized importance. The American College of Veterinary Pathologists says disease diagnosis across companion, food-producing, and wildlife species is central to veterinary pathology, and notes that veterinary pathologists also contribute to drug discovery and development. Longstanding workforce discussions in the specialty have also emphasized that pathology capacity affects not just case diagnosis, but research, toxicology, teaching, and regulatory work. A 2005 workforce commentary described an insufficient training pipeline for veterinary pathologists, while a separate review of specialist training needs pointed to chronic shortages across diagnostic specialties, including pathology.

The technician side of that system is less frequently discussed, but it’s built into how labs operate. Histology personnel prepare tissue sections from animal specimens, embed and section tissues, mount slides, apply stains, and support lab supervision and workflow, according to career guidance from the Virginia Health Workforce Development Authority. In veterinary settings, those tasks sit directly upstream of diagnosis. A current Texas A&M Veterinary Medical Diagnostic Laboratory posting for a histopathology diagnostic technician describes duties including trimming formalin-fixed animal tissue, paraffin embedding, microtomy, coverslipping, and stain preparation, underscoring how specialized and hands-on the role is in day-to-day diagnostic work. (vhwda.org)
Accreditation standards reinforce that this is not optional support work. The American Association of Veterinary Laboratory Diagnosticians’ requirements for accredited veterinary medical diagnostic laboratories list histotechnology among technical and clerical staff functions and set minimum qualifications for laboratory technicians across pathology and related sections. In other words, recognized lab quality systems already treat technical staffing as part of the infrastructure needed for dependable veterinary diagnostics. (aavld.org)
The broader literature also shows how often pathology technicians are embedded in research and teaching, even when they’re acknowledged only briefly. Recent and past veterinary studies indexed by MDPI credit pathology technicians with sample collection and processing in areas ranging from equine bone research to wildlife infectious disease surveillance. Separate veterinary education research has highlighted the growing use of digital pathology platforms for student training, suggesting that technical teams may play an increasing role not just in wet-lab preparation, but also in slide digitization and teaching support. That mirrors commentary from outside veterinary medicine arguing that digital pathology and automation are beginning to change histotechnology workflows rather than replace the need for specialized technical expertise.

Expert reaction specific to this review appears limited so far, but the surrounding industry conversation is consistent with its thesis. Workforce and laboratory sources continue to describe histology and pathology technical roles as highly specialized, hard to staff, and vulnerable to low visibility among trainees. One recent industry commentary called histotechs “the new unicorns,” reflecting recruitment difficulty in pathology labs, while a 2024 workforce article argued that better classification and recognition are needed to make shortages easier to measure and address. That’s human healthcare language, but the underlying pressures, awareness gaps, and training bottlenecks are relevant to veterinary laboratories as well. This is an inference based on parallel workforce reporting, not a claim that the veterinary market is identical. (labcorp.com)
Why it matters: For veterinarians, pathologists, and diagnostic lab leaders, the review is a useful prompt to think about pathology quality as a team output. Slide interpretation may be the visible endpoint, but the validity of that interpretation depends on fixation, trimming, embedding, sectioning, staining, documentation, and workflow control. In practice, that means technician recruitment, retention, training, and career development are quality issues, not just HR issues. It also means teaching hospitals and veterinary schools may need to think more deliberately about exposing students and trainees to pathology laboratory careers, especially as digital pathology expands and workforce strain persists across the veterinary sector. (aavld.org)
What to watch: The next signal will be whether veterinary colleges, diagnostic labs, and professional groups translate this kind of recognition into more formal workforce planning, clearer training pathways, and updated role design as digital pathology becomes more common. (vetlabassoc.com)
