with physical slide storage, transportation/shipping, and microscope maintenance since having high- capacity digital pathology scanners reduces reliance on having several traditional microscopes, minimizing the need for maintenance, repairs, and associated costs.

Enhanced Patient Care: Digital pathology enables better treatment decisions and improved

patient outcomes. More accurate diagnoses and efficient consultations reduce clinical costs and

enhance patient care quality.

• Scalability: Digital pathology offers scalability to accommodate growing demands without

significant infrastructure expansions. Laboratories can handle increased sample volumes efficiently, avoiding costly investments in physical resources.

• Additional Financial Benefits: Embracing digital pathology can lead to reduced patient or

consulting pathologist travel expenses. Remote consultations and access to expert opinions without physical travel save patients and healthcare providers money. By embracing digital pathology, laboratories, and healthcare systems can achieve substantial cost

savings while enhancing patient care and improving overall operational efficiency.


The advantages of going digital in pathology are undeniable. Improved efficiency, enhanced
