The laboratory medicine community is aware that healthcare stands on the cusp of a profound AI-driven transformation. Pathology faces daunting workloads. Examining tissue samples for cancer or other abnormalities under the microscope can be exceptionally time-consuming, and human attention inevitably varies. AI systems have recently demonstrated remarkable speed and accuracy in detecting malignant cells, allowing pathologists to cut review times dramatically.
In one study, using an AI-assisted workflow sliced the time spent per slide by more than half, while also boosting cancer detection rates. Over time, this should reduce missed cases, lower costs, and expand access to high-quality pathology services across more regions.
Pathology and laboratory medicine are not alone when it comes to the inevitable shift towards AI-powered solutions. Particularly in other specialties that are dependent on image interpretation, we are already seeing AI match or even exceed human performance in key diagnostic tasks. The AI revolution is both real and urgent, promising faster, more accurate, and more accessible patient care.
Take radiology, for example, which takes the lionshare of over 700 AI algorithms that have already been cleared by the FDA to support clinicians. The need is clear: radiologists – like pathologists – interpret countless images and must grapple daily with fatigue, growing caseloads, and the risk of missed findings. Studies suggest that AI can quickly pinpoint subtle abnormalities that even the most seasoned radiologists might overlook after hours of image review. In one large study of mammograms, an AI-assisted approach flagged 20 percent more cancers than radiologists working without computer aid, while simultaneously reducing overall workload. Such results highlight the promise of an AI that can elevate quality, reduce errors, and ensure more consistent outcomes.
Dermatology is another specialty profoundly impacted by AI’s image-recognition prowess. Deep learning algorithms can already identify melanoma or other skin cancers from photographs of suspicious lesions with a level of accuracy that surpasses many dermatologists. Shifting resources from unnecessary biopsies to earlier essential biopsies could have a tremendous impact on patient outcomes; early detection is often the key to successful cancer treatment.
Ophthalmology is witnessing similar breakthroughs. AI systems such as IDx-DR, approved by the FDA, can independently diagnose diabetic retinopathy from retinal images without a specialist’s interpretation. This innovation allows primary care clinics to catch eye disease early, offering a lifeline for many diabetic patients who might otherwise skip yearly eye exams.
Beyond these visually oriented fields, primary care and internal medicine may experience their own seismic shift. Large language models (LLMs) like ChatGPT excel at analyzing patient histories, symptoms, and lab data to suggest possible diagnoses or triage levels. In recent trials, LLMs often matched or surpassed general physicians in diagnostic accuracy, correctly ranking the eventual diagnosis among their top suggestions in most cases. These systems could act as triage “assistants,” helping frontline doctors capture subtle red flags or identify which patients might need urgent care.
Meanwhile, consumer-facing apps are evolving into robust symptom checkers that guide patients on whether to seek immediate attention or try home remedies first. Tools that let individuals photograph moles or ear infections for instant analysis, or wearables that detect arrhythmias in real time, help identify serious issues early or spare unnecessary office visits.
Future scenarios might feature a suite of smart home devices, including scales, blood pressure cuffs, and even camera-enabled kits-that continuously relay health data to AI systems. When a significant deviation is detected, a prompt alert could direct the patient to contact a healthcare provider for intervention, shifting the focus from reactive treatment to proactive prevention.
The true revolution, then, will be in bringing these disparate systems together to achieve a truly holistic health care approach. Only when our digitized systems are truly interoperable will AI be able to interrogate a patient’s entire health profile. The apps and algorithms must be built around a connected system to deliver on AI’s potential to expand access to expert level care.
Imagine a future with pathology and laboratory medicine at the center of that network, with AI acting as the glue that binds these previously siloed specialties.
