What is ISO 23640:2011-In vitro diagnostic medical devices — Evaluation of stability of in vitro diagnostic reagents?
ISO 23640:2011 provides guidelines for the evaluation of stability of in vitro diagnostic (IVD) reagents. In vitro diagnostic reagents are substances or preparations used in diagnostic examinations performed outside the living body, typically in a laboratory setting.
The stability of IVD reagents refers to their ability to maintain their intended performance characteristics, such as accuracy and reliability, throughout their shelf life. Proper stability testing is crucial to ensure the consistent performance of these reagents over time, as they are often used for diagnosing diseases and monitoring patient health.
ISO 23640 outlines the general principles and procedures for evaluating the stability of IVD reagents. It provides guidance on various aspects of stability testing, including test design, sample preparation, storage conditions, and performance evaluation. The standard helps manufacturers, regulatory authorities, and laboratories establish appropriate protocols for assessing the stability of IVD reagents.
By following the guidelines outlined in the standard, manufacturers can ensure that the IVD reagents they produce meet the necessary stability requirements, and laboratories can assess the reliability of these reagents before using them for diagnostic purposes. This standard contributes to the overall quality and safety of in vitro diagnostic testing.
Requirements of ISO 23640:2011
Test Design: The standard emphasizes the importance of designing stability tests that are appropriate for the specific characteristics of the IVD reagents. This includes considering factors such as the intended use of the reagent, its composition, and any potential interactions with the sample or other components.

This may involve dilution, mixing, or other techniques to ensure the stability of the reagent is accurately assessed. The standard also discusses the need for appropriate controls and replicates in stability testing.
Storage Conditions: The standard outlines requirements for storage conditions during stability testing. This includes parameters such as temperature, humidity, and light exposure, which should be selected based on the expected storage and use conditions of the reagent. The duration of the stability study should also be determined based on the intended shelf life of the reagent.
Performance Evaluation: The standard provides guidance on the assessment of performance parameters during stability testing. This may include evaluating the accuracy, precision, sensitivity, specificity, and other relevant characteristics of the reagent over time. The standard also discusses statistical analysis methods for interpreting the stability data.
Documentation: The standard emphasizes the importance of documenting all aspects of the stability evaluation process. This includes recording details of the test design, sample preparation, storage conditions, and results obtained. Adequate documentation is essential for traceability, regulatory compliance, and ensuring the reproducibility of stability studies.
Overall, ISO 23640:2011 provides general guidance and principles for the evaluation of stability. The specific requirements and testing protocols may vary depending on the type of IVD reagent, its intended use, and regional regulatory requirements. Manufacturers and laboratories should refer to the complete standard for comprehensive guidance on evaluating the stability of in vitro diagnostic reagents.
