Research Use Only

Meaning

Research Use Only, designated as RUO, is a regulatory classification applied to reagents, instruments, or other products that are strictly intended for use in laboratory research and are explicitly prohibited from use in clinical diagnostic or therapeutic procedures. This designation signifies that the product has not undergone the rigorous validation, quality control, and regulatory clearance required for clinical application. RUO materials are essential tools for advancing scientific discovery and developing new methodologies.
