Pathology has traditionally depended on physical glass slides, microscopes, manual documentation, and in-person slide review. While these methods remain important, advances in digital technology are changing how pathology laboratories manage, view, share, and analyze diagnostic information.
Digital pathology is one of the most important developments in modern laboratory medicine. It allows pathology slides to be scanned into high-resolution digital images that can be stored, accessed, reviewed, and analyzed using digital systems.
In 2026, digital pathology is moving beyond simple slide digitization. Its development is increasingly connected with artificial intelligence (AI), image analysis, laboratory information systems (LIS), cloud technologies, remote collaboration, and data-driven diagnostics.
This guide explains what digital pathology is, its benefits and challenges, how it works, and what the future may look like for diagnostic laboratories.
What Is Digital Pathology?
Digital pathology is the process of converting physical pathology slides into high-resolution digital images using specialized slide scanners.
Instead of relying only on a physical microscope and glass slide, pathologists can view digital slide images using computer systems.
A simplified digital pathology workflow looks like this:
Sample Collection → Tissue Processing → Slide Preparation → Slide Scanning → Digital Image → Pathologist Review → Report
Digital pathology can support the storage, retrieval, sharing, and analysis of pathology images.
Depending on the setup, digital pathology may also be integrated with laboratory information systems and other healthcare technologies.
How Does Digital Pathology Work?
A typical digital pathology workflow involves several stages.
1. Sample Collection
A tissue or specimen is collected from the patient according to the required diagnostic procedure.
2. Slide Preparation
The specimen is processed and prepared on a glass slide using standard laboratory procedures.
3. Slide Scanning
A digital slide scanner captures a high-resolution image of the slide.
The resulting file is commonly referred to as a whole-slide image (WSI).
4. Digital Storage
The digital slide can be stored electronically and associated with the relevant patient and case information.
5. Digital Review
Pathologists can view and navigate the digital slide using specialized software.
6. Analysis and Reporting
The pathologist reviews the image, interprets the findings, and prepares the diagnostic report.
Digital tools and AI-based image analysis may also assist with certain workflows, depending on the laboratory’s technology and intended use.
8 Major Benefits of Digital Pathology
1. Easier Access to Pathology Slides
One of the biggest advantages of digital pathology is accessibility.
Instead of physically transporting glass slides, authorized users can access digital images through appropriate systems.
This can be particularly useful for laboratories with multiple locations or specialists working remotely.
2. Remote Collaboration
Digital pathology can make it easier for pathologists and specialists to collaborate on cases.
For example, an authorized specialist in another location may be able to review a digital slide without requiring the physical slide to be transported.
This can support:
- Second opinions
- Specialist consultations
- Multi-location collaboration
- Remote case review
- Educational discussions
The availability of these capabilities depends on the laboratory’s infrastructure, software, security controls, and regulatory requirements.
3. Better Organization of Digital Records
Physical slides require dedicated storage and careful organization.
Digital pathology allows scanned images to be associated with electronic case information.
When integrated with laboratory systems, pathology images can potentially be connected with:
- Patient information
- Sample information
- Test details
- Case history
- Pathology reports
This can make case retrieval and information management more efficient.
4. Support for AI and Image Analysis
Digital pathology provides the digital images required for computer-based image analysis.
AI systems can potentially analyze whole-slide images to identify patterns or areas of interest.
Potential applications include:
- Cell detection
- Tissue classification
- Image segmentation
- Quantitative analysis
- Pattern recognition
- Identification of suspicious regions
AI should be considered a decision-support technology, and appropriate professional review remains essential.

8. Data-Driven Pathology
Once pathology information becomes digital, it becomes easier to combine images with structured laboratory data.
This can create opportunities for:
- Image analytics
- AI development
- Research
- Quality monitoring
- Population-level analysis
- Workflow analytics
This is one of the reasons digital pathology is increasingly viewed as a foundation for future data-driven pathology.
Digital Pathology and AI
Digital pathology and artificial intelligence are closely connected.
AI requires digital data to perform image analysis, and whole-slide images provide a rich source of visual information.
A future-oriented workflow may look like:
Tissue Sample → Digital Slide → AI-Assisted Analysis → Pathologist Review → Final Report
AI may help identify areas of interest, perform quantitative measurements, classify patterns, or prioritize cases depending on the specific application.
However, AI does not eliminate the need for a pathologist.
The final interpretation should remain under appropriate professional oversight.
Digital Pathology and LIS Integration
A Laboratory Information System (LIS) manages laboratory information such as patient records, test orders, samples, results, and reports.
When digital pathology is integrated with an LIS, the workflow can become more connected.
For example:
Patient Registration
↓
Test / Pathology Order
↓
Sample Collection
↓
Slide Preparation
↓
Digital Slide Scanning
↓
Digital Image Review
↓
Pathology Report
↓
Report Delivery
This reduces the need to manage patient, laboratory, and pathology information in completely separate systems.
