Pathology has always relied on a mix of skilled hands and trained eyes. A pathologist studies tissue under a microscope, recognizes patterns, and delivers a diagnosis that shapes a patient’s treatment. That core work hasn’t changed. What has changed is nearly everything around it.
Today’s pathology labs run on a network of software, automation, and digital tools that help them handle more cases, reduce errors, and deliver answers faster. Some of these technologies have been around for years, while others are just starting to reshape the field. Here’s a closer look at how pathology labs put technology to work.
The Anatomic Pathology LIS as the Foundation
Every modern pathology lab builds its operations around an anatomic pathology laboratory information system. This software manages each case from the moment a specimen arrives until the pathologist signs out the final report.
Anatomic pathology workflows look very different from high-volume clinical testing. A single case might include several specimens, each divided into multiple blocks, each producing multiple slides, plus special stains and molecular tests ordered along the way. A general-purpose system often struggles to keep up with that complexity. An AP-focused LIS handles it by:
- Organizing work around cases rather than single test results
- Tracking every specimen, block, and slide in a parent-child structure
- Managing orders for special stains, immunohistochemistry, and molecular tests
- Supporting gross descriptions, microscopic findings, and final diagnoses
- Routing cases to the right pathologist based on specialty or workload
- Generating reports and delivering them to providers and electronic health records
Without a strong LIS, every other technology in the lab works in isolation. With one, the pieces connect.
Barcoding and Specimen Tracking in Histology
The histology lab turns tissue into slides, and it’s one of the busiest and most error-prone parts of any pathology operation. Technicians handle dozens of nearly identical cassettes and slides every hour, often under time pressure.
Labs reduce mix-ups by pairing their LIS with cassette printers, slide printers, and barcode scanners. When a grossing technician creates blocks, the system prints labeled cassettes on demand. When a histotechnologist cuts slides, the system prints matching slide labels. Staff scan items at each station, so the lab always knows where every piece of tissue sits.
This approach does more than prevent errors. It also gives lab managers real-time visibility into bottlenecks, such as a backlog at embedding or a delay at the microtome, so they can shift staff where they’re needed.
Automation in Tissue Processing and Staining
Pathology labs have steadily automated repetitive, hands-on tasks. Modern equipment includes:
- Tissue processors that prepare specimens for embedding on a set schedule
- Automated stainers for routine H&E slides
- Advanced platforms for immunohistochemistry and special stains
- Automated coverslippers that finish slides quickly and consistently
Automation delivers more consistent staining quality, which makes slides easier to read and compare. It also frees skilled histotechnologists to focus on work that truly requires their expertise. When instruments connect to the LIS, they can receive protocols directly and report back their status, which cuts down on manual entry.
Voice Recognition and Structured Reporting
Documentation takes up a surprising share of a pathologist’s day. Many labs now use voice recognition software so pathologists and pathologists’ assistants can dictate gross descriptions and diagnoses directly into the system. This removes the delay of sending recordings to transcriptionists and lets pathologists review and sign out reports faster.
Labs also rely on synoptic reporting templates, especially for cancer cases. These structured templates prompt the pathologist to include every required data point, such as tumor size, grade, margins, and lymph node status. Oncologists get complete, consistent reports that are easy to scan, and labs stay aligned with accreditation standards.
Digital Pathology and Whole-Slide Imaging
Digital pathology represents one of the biggest shifts the field has seen in decades. Whole-slide scanners capture glass slides as high-resolution digital images, which pathologists can review on a monitor instead of a microscope.
Labs that adopt digital pathology software gain several advantages:
- Pathologists can review cases from anywhere with a secure connection
- Labs can share cases with subspecialists for second opinions in minutes instead of days
- Digital archives replace bulky physical slide storage and make old cases easy to retrieve
- Tumor boards can display cases on screen for the whole care team
- Teaching and training programs gain easy access to large libraries of cases
The real value comes when the digital images live inside the same workflow as the case data. When the LIS and the image viewer work together, a pathologist can open a case and see the slides, history, and prior reports without jumping between systems.
Artificial Intelligence as a Pathologist’s Assistant
Once slides exist in digital form, AI tools can analyze them. Pathology labs have started using algorithms that help with tasks like:
- Counting mitotic figures or measuring biomarker expression
- Highlighting areas of a slide that may contain cancer
- Screening routine cases so pathologists can focus on the most complex ones
- Scoring certain stains more consistently than manual review
These tools don’t replace pathologists. They act as a second set of eyes and a productivity boost, handling tedious measurements and helping reviewers prioritize. As more AI tools earn regulatory clearance and prove their accuracy, expect adoption to grow.
Telepathology and Remote Sign-Out
Many hospitals, especially smaller and rural ones, don’t have a pathologist on site at all times. Telepathology fills that gap. During surgery, for example, a surgeon may need a quick frozen section diagnosis to decide how to proceed. With telepathology, a pathologist at another location can view the tissue remotely and deliver a real-time answer.
Remote sign-out has also become a practical way to address staffing shortages. Cloud-based LIS platforms let pathologists access cases, review digital slides, and sign reports from home or another facility. Labs can balance workloads across locations and bring in subspecialty expertise without relocating anyone.
Integrating Molecular and Genomic Testing
Cancer care increasingly depends on molecular testing that identifies specific mutations and guides targeted therapies. Pathology labs sit at the center of this process, since they select the tissue, send it for testing, and often combine molecular findings with their own diagnosis.
Labs use technology to connect these pieces. The LIS can track molecular orders, send specimens to in-house or outside labs, receive results electronically, and fold them into an integrated report. Oncologists then get a complete picture in one place, rather than piecing together separate reports.
Data and Analytics for Smarter Operations
Pathology labs generate a huge amount of operational data, and more labs now put it to use. Dashboards and reporting tools help lab leaders track:
- Turnaround times by case type, location, and pathologist
- Workload distribution across the team
- Specimen volumes and seasonal trends
- Quality metrics like amended reports and diagnostic discrepancies
- Billing performance and denied claims
With this information, lab managers can make smarter staffing decisions, catch problems early, and show hospital partners and referring physicians how well the lab performs.
Connecting to the Wider Healthcare System
Pathology results matter only when they reach the people who need them. Labs rely on interfaces that connect their LIS to electronic health records, practice management systems, billing platforms, and cancer registries. These connections let orders flow in and results flow out without manual re-entry, and they help ensure reports reach the ordering physician quickly and reliably.
Strong interoperability also helps outreach labs win and keep business from physician practices, since clinics want results that land directly in their own systems.
The Bottom Line
Pathology still depends on the judgment and expertise of trained professionals. Technology doesn’t change that. Instead, it removes friction from the process, reduces the risk of errors, and gives pathologists better tools to do their work. From barcoded cassettes and automated stainers to digital slides, AI assistance, and remote sign-out, today’s pathology labs combine many technologies into one connected workflow. The labs that do it well handle more cases with greater accuracy and deliver faster answers to the physicians and patients who depend on them.
