Introduction: Trichomonas vaginalis is the third prevalent cause of vaginitis. Because of lack of precise diagnosing methods and the similarity of its symptoms with other STD, diagnosis of trichomoniasis is not an easy effort. Valid resources pointed out that diagnosis of trichomonas vaginitis merely based on clinical signs is not possible, but on the basis of the test results. Thereupon, this research is accomplished to compare clinical and laboratorial methods in diagnosis of trichomonas vaginitis.
Methods: This observational research was accomplished on 550 women with vaginitis infection. Eligible women with signs of vaginitis infection were examined and sample of vaginal discharge taken for wet smear testing. Data were gathered by means of interviews and observation forms, and analyzed by SPSS software version 14.5 and descriptive statistics.
Results: The tests performed on 550 patients suffering from vaginal infection shows that 54 cases of trichomoniasis were positive. According to the clinical observation of the subjects, 14.54% had infection; while on the basis of microscopic diagnosis 9.81% were trichomonas positive. 10.18% of the patients that were trichomonas positive in clinical observation, their microscopic observation result were negative. The result of investigations indicated that, 5.45% that were trichomonas negative in clinical observation, were positive in microscopic observation.
Conclusion: Lake of application of laboratorial method in identifying vaginitis patients may lead to incorrect diagnosis, so it is suggested to utilize laboratorial results in precise diagnosis.
