A certified reference material (CRM) is the best choice when it comes to purchasing a chemical standard for precise quantitation of a poison in biological fluids. CRM is a high-quality reference material that is provided with a certificate of analysis that proves its accuracy and traceability to a recognized measurement system. This means that the CRM has been thoroughly characterized and tested by an independent organization to confirm that its properties are accurate and reliable.
