Summary

This is an observational, non-interventional diagnostic accuracy study designed to evaluate a diquat quantitative detection kit (ambient ionization mass spectrometry method) and a portable mass spectrometry analysis system for measuring diquat concentrations in human blood samples (whole blood/plasma), using LC-MS/MS as the clinical gold standard for comparison.

Conditions

  • Diquat Poisoning

Interventions

DEVICE

Portable Mass Spectrometry Analysis System for Quantitative Diquat Detection (with Diquat Quantitative Detection Kit; In-Situ/Ambient Ionization Mass Spectrometry Method)

The portable mass spectrometry analysis system is an in vitro diagnostic device used with a diquat quantitative detection kit based on an in-situ/ambient ionization mass spectrometry method to quantify diquat concentrations in human blood samples. Whole blood specimens collected in routine clinical care will be analyzed using this device, and the quantitative results will be compared against those obtained using the reference standard method, liquid chromatography-tandem mass spectrometry (LC-MS/MS), to evaluate analytical accuracy and agreement. Each specimen will be tested repeatedly (three measurements per sample), and the mean value will be used for statistical analysis. The study is observational and non-interventional, and test results generated by the portable mass spectrometry system are used for research evaluation purposes and do not alter routine clinical diagnosis or treatment decisions
