Abstract: Objective: To evaluate the internal quality control(IQC) of vaginal secretions(leucorrhea)routine testing. Methods:Total 1 235 samples were included in this study. Five samples were randomly selected every day from leucorrhea testing by suspension. The smears stained with Wright’s were conducted by microscopic examination. Those suspicious samples with positive neisseria gonorrhoeae were rechecked by Gram stain,to assess the quality of suspecsion assay. The quality of normal saline was monthly checked by microscopic examination in direct smear or centrifugal sediment. Results:Among 12 months in 2011, besides the compliance rates of clue cells only in July and September were not qualified, 74.3% and 78.1% respectively, those rates in other months matched the standard of 82.5%-100%,the monthly average 90.2%-94.7%,suggesting that the testing quality was excellent. The compliance rate of trichomonas was highest(99.3%) in pathogens,while the compliance rate of clue cells was lowest(83.1%). The quality normal saline was eligible. Conclusions:The IQC of routine leucorrhea suspension testing, which established by Wright’s method,can effectively ensure the testing quality in clinical practice.
