Reliable and comparable measurement results are key to reduce health-care costs, improve clinical management and lower the risk of medical error. Efficient, resilient and safer food production systems rely on verification through monitoring and measurements. The reduction of pollutants in the environment to levels no longer considered harmful to humans and nature requires consistent monitoring are based on reliable measurement results. The competitiveness of the EU economy and the smooth functioning of international trade also depend on reliable measurements. State-of-the-art RMs can also play a crucial role in emerging EU focus areas such as biotechnology and preparedness and response to health crises like pandemics or widespread food products contaminations.</p><p>At the heart of reliable measurements are RMs. They provide a benchmark for analytical laboratories around the world to deliver accurate results. Testing laboratories use CRMs to calibrate their measuring instruments. Additionally, RMs are also used as quality control assurance tools, proving that obtained measurement results are correct, helping to eliminate the need to duplicate or dispute testing data.</p><p>The JRC is one of the major developers and producers of reference materials in the world. It currently provides over 760 reference materials under the BCR, IRMM, EURM and ERM brands, and distributes around 20,000 units per year to testing laboratories worldwide. The JRC has RM production facilities unique in the world, including specialised laboratories and a pilot plant for material processing. </p><p>JRC鈥檚 reference materials can be ordered directly from the JRC, Geel or from one of its authorised distributors.</p><p>Check the <a href="https://crm.jrc.ec.europa.eu/">Certified Reference Materials Catalogue</a> for the full catalogue of reference materials, ordering, user support, application noticed and frequently asked questions.</p></div> </div> <div class="ecl-u-mb-2xl"> <a id="paragraph_5167"></a> <div class="ecl-content-item-block"><div class="ecl-row"><div class="ecl-content-item-block__item contextual-region ecl-u-mb-l ecl-col-12 ecl-col-l-3 "><article class="ecl-card" ><picture class="ecl-picture ecl-card__picture" data-ecl-picture-link ><img class="ecl-card__image" src="/sites/default/files/styles/oe_theme_ratio_3_2_medium/public/2013-05/jrc-irmm-rms-for-clinical-chemistry_0.jpg?itok=h5jNEP5_" alt="jrc-irmm-rms-for-clinical-chemistry_0.jpg" ></picture><div class="ecl-card__body"><div class="ecl-content-block ecl-card__content-block" data-ecl-auto-init="ContentBlock" data-ecl-content-block ><div class="ecl-content-block__title"data-ecl-title-link><a href="/scientific-activities-z/certified-reference-materials/reference-materials-clinical-analysis_en?prefLang=pt" class="ecl-link ecl-link--standalone" >Reference materials for clinical analysis</a></div><div class="ecl-content-block__description"><div class="ecl"><p>Good health care requires reliable measurements of health status and disease markers.
