Abstract

Microbial limit testing of pharmaceuticals is one of the core aspects of pharmaceutical quality control. The accuracy of its test results is directly related to drug safety, efficacy, and the prevention and control of clinical medication risks. As the testing process involves multiple stages, such as sample processing, experimental environment, operational procedures, and instrument and equipment usage, it is susceptible to various interfering factors that may lead to testing errors, thereby affecting the scientific validity and reliability of drug quality evaluation. Based on recent research advances in the field of pharmaceutical microbial limit testing, this paper systematically analyzes the main factors influencing testing errors, including personnel operation, instruments and equipment, experimental materials, testing methods, and environmental conditions. Corresponding preventive measures are proposed accordingly, aiming to standardize testing procedures, reduce testing errors, and enhance the accuracy of test results. This study provides theoretical reference and practical guidance for the standardized implementation of pharmaceutical microbial limit testing.
