Abstract:
      Several evaluation standards of method detection limit (MDL) have been reported in literatures. It is important to understand and use correctly these standards so that it could obtain reliable parameters for guiding base laboratories. In this paper, the evaluation standards of MDL at home and aboard were systemic analyzed and summarized, and their features, application scope and key points were introduced. Comparison results of three typical evaluation standards were presented using real data sets from literatures and the author’s laboratory. The modified procedure for the evaluation of MDL was proposed for different laboratory requirements according to scientific and maneuverability principles.
