Overview
EN ISO 19001:2013 (ISO 19001:2013) defines the information that manufacturers must supply with in vitro diagnostic (IVD) reagents used for staining in biology. Published by CEN/ISO, it applies to producers, suppliers and vendors of dyes, stains, chromogenic reagents, fluorochromes, antibodies and other reagents used in histology, cytology, bacteriology, haematology and histochemistry for both routine and research use. The standard’s objective is to ensure that labelling and product information enable comparable and reproducible staining results across laboratories.
Key topics and requirements
EN ISO 19001:2013 focuses on the content and format of manufacturer-supplied information (labelling, instructions for use). Key technical topics include:
- Scope and applicability
- Reagents for staining in biology used in medical laboratories (routine and research).
- Format and units
- Chain of suppliers
- Manufacturers must ensure upstream suppliers meet quality-system expectations (e.g., ISO 9001, ISO 13485).
- Warnings and precautions
- Product identification
- Product name should include relevant identifiers where applicable (CAS registry number, Colour Index name/number).
- Product identity and batch data
- Physico‑chemical data and batch-specific documentation, including:
- Molecular formula (including counter-ion)
- Molar mass (specify with/without counter-ion)
- Permissible limits for interfering substances
- Handling and storage instructions
- For coloured organic compounds: molar absorbance (or dye content), wavelength of maximum absorbance, and chromatographic data (TLC, HPLC, HPTLC).
- Suggested use and performance
- Recommended specimen types, pre‑treatment, test protocol(s) used by the manufacturer and expected results (Annex A provides example information).
Applications and users
Who uses EN ISO 19001:2013 and why:
- Manufacturers, suppliers and distributors of staining reagents - to produce compliant labelling, technical data sheets and instructions for use (IFU).
- Clinical and research laboratories (histology, cytology, bacteriology, haematology) - to select reagents with complete documentation that supports reliable, reproducible staining.
- Regulatory and quality teams - to demonstrate conformity with IVD labelling requirements and supply-chain quality controls.
- Procurement specialists - to compare product specifications using standardized identifiers (CAS, C.I. numbers).
Adoption of EN ISO 19001:2013 improves traceability, safety and inter-lab comparability of staining procedures.
