(1) The smear method is highly accurate for male acute urethritis, but not suitable for female patients; (2) The culture method is the most accurate, especially for female patients.

(2) Chlamydia trachomatis infection in the genital tract: secretion examination: ① smear method, to check neutrophils in urethral or cervical secretions, the method is simple, but the pathogen cannot be identified; ② Chlamydia trachomatis antigen detection method, simple, but has The sensitivity of the detection methods is not high; ③Polymerase chain reaction (PCR) and ligase chain reaction (LCR), which are molecular biology inspection methods, are to amplify the target DNA or RNA sequence with a limited number of specimens millions of times, Sensitivity is greatly improved.

(3) Syphilis: secretion examination: ① dark field microscopy, suitable for patients with chancroid damage; blood test: ② non-treponemal serological test, such as rapid plasma reagin test (RPR), which is a primary screening test, There may be false positives; ③ Treponema pallidum serological test, such as Treponema pallidum particle agglutination test (TPPA), is a confirmatory test for syphilis, but it cannot be used to judge curative effect, follow-up, etc.

(4) Condyloma acuminatum: Generally, the diagnosis can be made based on clinical manifestations. If necessary, 5% acetowhite test and histopathological examination or HPV test are performed.

(5) Genital herpes: Generally, the diagnosis can be made based on clinical manifestations, and the herpes simplex virus antigen test should be performed when necessary.

(6) AIDS: There are many detection methods, mainly divided into three categories: ① It is the detection of CD4 cells. When the CD4 cells are significantly reduced, AIDS infection is suspected. ② For the detection of etiology, the load of HIV virus should be detected, and the pathogen should be directly detected. ③ detection of HIV antibodies. There is a window period between HIV antibody infection and detection. With the continuous improvement of detection methods, the window period of detection will become shorter and shorter. The original detection method has a window period of about six to eight weeks. The current more advanced HIV detection methods can be significantly shortened to 14 to 21 days, which is two to three weeks. Therefore, different testing methods have different timeliness, and you can consult your local testing doctor.
