It may be influenced by some media exaggerated propaganda, in the clinic encountered a lot of patients, moving to ask doctors to check whether he has chlamydia or mycoplasma infection, and even some people simply do not have symptoms, feel very difficult, therefore, it is necessary to talk about the problems related to chlamydia mycoplasma here for your reference. Urethritis caused by chlamydial mycoplasma infection is also known as non-gonococcal urethritis. It is worth mentioning that mycoplasma is widely present in nature and can be detected in the genitourinary tract of normal people, and its pathogenicity is still being studied and discussed. The diagnosis of non-gonococcal urethritis in China is still mainly based on its history and clinical manifestations, and the examination is mainly based on the urogenital tract secretions seen under the microscope polymorphonuclear leukocytes and exclude gonococcal infection, not necessarily to make the pathogenetic examination. The method of examination of mycoplasma chlamydia mostly uses polymerase chain (PCR) test, because of the high requirements of laboratory conditions, prone to false positives due to contamination, the Ministry of Health has stipulated that this method is not used for clinical diagnosis at this stage, but many specialized hospitals are still applying it, resulting in low credibility of the results. Due to some problems with blood sampling for antibody testing, it is less commonly used in regular hospitals. And if you want to do culture, not only expensive, high requirements for experimental equipment, and it takes a lot of time. The author believes that for patients with clinical history and signs consistent with non-gonococcal urethritis, the examination of mycoplasma chlamydia is not necessary because it will not have an impact on the treatment, and it will cost a lot more, and the results may not be accurate.
