26、g the stability of a product, then determining and verifying the expiry date of the product that is placed on the market. To determine shelf life, transport stability, and in-use stability, the manufacturer performs an evaluation. In order to provide this important information to the customer, the m
27、anufacturer identifies critical factors that might influence stability of the IVD reagent and carefully evaluates these characteristics. Stability of the IVD reagent affects the performance of the device and therefore has an impact on patient results.It is the manufacturers responsibility to determi
28、ne and monitor stability of IVD reagents to ensure that performance characteristics of the product are maintained. This is best accomplished by developing a stability evaluation protocol, and producing valid data and analysis to establish appropriate shelf life, transport limitations and in-use stab
29、ility information, which are then provided to the customers.The basis for this ISO standard is EN 13640, Stability testing of in vitro diagnostic reagents2.ISO 23640:2011(E)iv ISO 2011 All rights reservedBS EN ISO 23640:2013Copyright European Committee for Standardization Provided by IHS under licen

This International Standard can also be applied to specimen collection devices that contain substances used to preserve samples or to ini
