In patients with trichomoniasis, the diagnosis can be confirmed if trichomonas is found in the vaginal secretions. The most simple method is the saline suspension method, where the trichomonas can be seen under the microscope in a wave-like motion and the increased white blood cells can be pushed. The sensitivity of this method can reach 60%-70%. 2. Culture of the secretion can be performed: the accuracy can reach about 98%. It is important to avoid sexual intercourse, vaginal irrigation or local medication 24-48 hours before taking the secretions, not to apply lubricant to the speculum when taking the secretions, and to send the secretions for examination in a timely manner and to keep them warm, otherwise the trichomonas activity will be weakened and it will be difficult to identify them. It has a sensitivity of 90% and a specificity of 99.8%. 4, Trichomonas can be checked by routine urine tests to see if there is trichomonas infection in the urine.
