AI can leverage large volumes of medical data to generate personalized interpretations of test results, shifting from defining normal values in general to defining them for specific individuals. Chemistry and immunology laboratories, with their large and structured datasets, are particularly well-suited to benefit from machine learning techniques.

Molecular Pathology and Digital Pathology

AI techniques have found applications in molecular pathology, particularly in the classification of central nervous system tumors using DNA methylation profiling. By analyzing DNA methylation patterns, AI models can accurately classify tumors, providing valuable insights for diagnosis and treatment planning. Digital pathology, which involves the analysis of digitized histopathology slides, also benefits from AI algorithms. Image analysis tools powered by AI can automate the interpretation of slides, assisting pathologists in identifying and quantifying various cellular features, ultimately improving accuracy and efficiency.

Predicting Laboratory Test Values and Optimizing Utilization

AI has shown promise in predicting laboratory test values based on patient data, aiding in early detection and diagnosis. For instance, a neural network model was used to predict iron-deficiency anemia and serum iron levels using features extracted from routine complete blood count results. Such predictions can guide healthcare professionals in timely interventions and tailored treatment plans.

Additionally, AI can optimize laboratory utilization by analyzing test ordering patterns and suggesting appropriate tests based on patient characteristics. Machine learning models have been developed to recommend laboratory tests, reducing unnecessary testing and improving resource allocation. These AI-based approaches hold great potential for streamlining laboratory workflows and improving efficiency.
