How to check non-gonococcal urethritis

Nongonococcal urethritis examination methods include pathogen examination, bacterial culture, antigen detection, nucleic acid detection, etc.

1, pathogen examination

Take urethral secretions as samples, and then carry out Gram staining, through high-power microscope to find Gram-negative diplococcus.

2, bacterial culture

Take urethral secretions, inoculated in culture medium, 37℃ culture for 24 hours, observe bacterial growth, and do colony morphology identification.

3, antigen detection

using ELISA or chemiluminescence method to detect mycoplasma, chlamydia antibody in the patient's serum, if the antibody is positive, it indicates infection with mycoplasma or chlamydia.

4, nucleic acid detection

using polymerase chain reaction to detect mycoplasma, chlamydia DNA in the patient's urethral secretions, if positive, it indicates infection with mycoplasma or chlamydia.
