Abstract:
Background Vaginal microbial morphology detection is the main detection method for vaginal infectious diseases, mainly by artificial microscopy, which is time-consuming and has obvious subjective bias. The existing problems can be solved effectively by the automatic vaginal microbial morphology detector based on deep learning, but rigorous controlled test verification is necessary before it is put into use.
Objective To analyze the effectiveness of GY66 automatic detector in vaginal microecological morphological detection.
Methods Totally 303 samples of vaginal secretions were collected from outpatients in the Department of Obstetrics and Gynecology of the First Medical Center of Chinese PLA General Hospital from December 1, 2020 to July 31, 2021. The samples were detected by two detection methods, that were automatic GY66 vaginal microecological detector and manual microscopy after Gram stain. And the detection results were compared, included trichomonas, mold, clue cells and cleanliness. Taking the manual microscopy results as gold standard, the clinical performance of automatic GY66 detector for detecting vaginal microecological formed components was evaluated.
Results There was no statistic difference in the overall detection rates of mold, clue cells and trichomonas between automatic GY66 detector and manual microscopy (P>0.05). The total coincidence rates of mold, trichomonas, clue cells or cleanliness detected by automatic GY66 detector were 98.68%, 99.67%, 99.67% and 97.69% respectively, which were highly consistent with manual microscopy (Kappa values were 0.961, 0.982, 0.939 and 0.950) with no statistical significance. High-concentration positive samples in anti-jamming and cross-contamination tests did not affect the results of the next blank sample. The microscopic examination by GY66 detector was performed in 3 random samples, 3 times for each sample, and the repeatability test results were consistent.
Conclusion The automatic vaginal microecological detection method based on deep learning has good effectiveness in vaginal secretion examination, which can quickly provide reliable and accurate microscopic examination results for clinical practice.
