Companion Diagnostics Expansion Drives Molecular Reagent Demand
Companion diagnostic testing requirements are expanding across a growing range of oncology indications as targeted therapies increasingly require biomarker confirmation before treatment initiation, pushing pathology laboratories to adopt in situ hybridization and immunohistochemistry reagents capable of identifying specific genetic alterations and protein expression levels that routine hematoxylin and eosin staining cannot detect. This is driving laboratories to work directly with specialized reagent developers on validated assay panels rather than relying solely on general-purpose staining protocols. Suppliers with proven regulatory-validated reagent portfolios are capturing disproportionate share of this fast-growing demand pool relative to competitors offering only routine staining products.
Market Impact: Adds testing volume worth $480M annually
