Elsevier ImmunoQuery is a specialized evidence-based decision support system for immunohistochemistry (IHC), designed to help pathologists reach accurate diagnoses faster. It draws on data from 3,400,000+ patient cases, 9,700+ references, 64,000+ unique antibody-diagnosis relationships, and 5,100+ antibodies across 2,000+ diagnoses — making it one of the most comprehensive IHC databases available to practicing pathologists.
ImmunoQuery's Build Dx Panel feature allows pathologists to query up to three differential diagnoses simultaneously and identify which of 5,100+ antibodies will most effectively confirm or differentiate the diagnosis. Each result includes complete IHC profiles showing percent positivity of all antibodies tested, staining patterns, and a full list of references with abstract access — helping pathologists design cost-effective, high-value staining panels rather than ordering unnecessary tests.
ImmunoQuery allows pathologists to standardise diagnostic queries to align with WHO nomenclature, with diagnoses from a number of organ systems available in WHO format. This standardisation helps laboratories maintain consistency in how diagnoses are classified and communicated, supporting alignment with international pathology standards and reducing interpretation variability across teams and institutions.
ImmunoQuery and ExpertPath are designed to work as complementary tools: ExpertPath provides sub-specialist-driven anatomic and clinical pathology knowledge across 5,200+ diagnoses, while ImmunoQuery contributes definitive, evidence-based IHC data spanning millions of patient cases. Together, they give pathologists both the diagnostic framework and the antibody-level evidence needed to ensure accuracy, efficiency, and flexibility in even the most demanding diagnostic workflows.
Pathologists in the United States can earn AMA PRA Category 1 Credit™ toward point-of-care learning through ImmunoQuery search queries, allowing them to meet CME requirements as a natural byproduct of daily diagnostic work. This feature embeds continuing education into clinical practice rather than treating it as a separate activity, helping pathologists maintain board certification more efficiently.
