Vaginal microecological evaluation is essential for the diagnosis and treatment of gynecological infectious diseases. However, the processes of specimen collection and pretreatment, quality control, morphological and chemical examination, result reporting and clinical application remain inadequately standardized across medical institutions at various levels. To address these inconsistencies, the Clinical Laboratory Science and Technology Transformation Professional Committee of the China Association for Promotion of Health Science and Technology and Branch of Clinical Laboratory Physicians of the Guangdong Medical Doctor Association convened a panel of experts in laboratory medicine and clinical practice. By integrating domestic and international standards, guidelines, and the latest research, and through a rigorous process of discussion, revision, and review, the panel formulated the "Expert Consensus on the Standardization of Clinical Laboratory Evaluation and Reporting of vaginal Microecology" (hereinafter referred to as the "Consensus"). This initiative aims to promote the standardized and consistent application of vaginal microecological evaluation.
