[Brief Discussion on Representative Models of Instruments for In Vitro Diagnostic Reagents]

Representative models of instruments for in vitro diagnostic (IVD) reagents simplify the performance evaluation of registration. Different from the concept of the US FDA instrument family, the domestic identification of representative models focuses on the risk analysis of instrument differences. However, there are problems such as unclear requirements for the identification of instruments, difficulties in the identification of new technology and high-risk instruments. The performance evaluation of the detection system can be partially simplified by representative models, and representative models can evaluate the performance of non-detection systems. Meanwhile, the comprehensive performance should be evaluated by representative models as conditions. Therefore, according to the analysis, performance evaluations using representative models can guarantee the safety and effectiveness of in vitro diagnostic reagents while promoting the high-quality development of the IVD industry.
