Exploration of Calibration Method for Immunoblot Analyzer

摘要: 针对免疫印迹分析仪的校准方法展开探讨，通过与已有免疫原理的体外诊断仪器比较，论证了开展校准方法的必要性。通过分析仪器的结构和工作原理，提出了校准所需的环境条件和设备要求，重点研究了全自动和半自动免疫印迹分析仪的计量特性、校准条件及校准方法，并详细阐述了进样体积示值误差、重复性以及泵流量稳定性等关键校准项目的实施步骤。研究旨在当前缺乏国家计量技术规范的情况下提供校准指导指南，为仪器的计量溯源提供技术参考，确保检测结果的准确性和可比性。

Abstract: This article explores the calibration methods for immunoblot analyzers and demonstrates the necessity of conducting calibration methods by comparing them with existing in vitro diagnostic instruments based on immunological principles. By analyzing the structure and working principle of the instrument, the environmental conditions and equipment requirements for calibration were proposed. The metrological characteristics, calibration conditions, and calibration methods of fully automatic and semi-automatic immunoblotting analyzers were studied in detail, and the implementation steps of key calibration items such as injection volume indication error, repeatability, and pump flow stability were elaborated. The research aims to provide calibration guidance guidelines in the current lack of national metrological technical specifications, provide technical references for instrument metrological traceability, and ensure the accuracy and comparability of test results.
