[Overview of Status of Medical Device Registration and Quality Evaluation Requirements for Clinical Mass Spectrometry].

Mass spectrometry technology is becoming an important tool for clinical analysis due to its high specificity, high sensitivity and high multi-component detection capability. The current applications of this technology are mainly in liquid chromatography-tandem mass spectrometry (LC-MS/MS), matrix-assisted laser desorptionionization time-of-flight mass spectrometry (MALDI-TOF-MS), inductively coupled plasma mass spectrometry (ICP-MS), gas chromatography-mass spectrometry (GC-MS) and the related in vitro diagnostic kits. At present, the number of medical device (MD) based on mass spectrometry technology is growing rapidly, especially the number of LC-MS/MS and MALDI-TOF-MS registered MD products, and the standardization of relevant product quality requirements is also being effectively carried out.

[Research on the Standardization System of Diagnosis Products at Home and Abroad].

Objective: The quality of diagnostic products is closely related to people's health. The standards and standardization system are essential to IVD industry and supervision.

Methods: Through a study of the standards of ISO, EU, the USA and China, a comparative analysis was carried out.
