What is the diagnosis of non-gonococcal urethritis?

Non-gonococcal urethritis is very common in life. Once the disease occurs and causes frequent urination, painful urination, and urgent urination, you should pay attention to examination. Through physical examination, direct immunofluorescence, enzyme-linked immunosorbent assay, Chlamydia trachomatis culture and other examinations, you can understand the patient's condition and get targeted treatment.

1. Physical examination

Physical examination is very important for non-gonococcal urethritis. It mainly judges the severity of the disease by observing the perineum visually and touching it, and observes the characteristics of the secretions when necessary. At the same time, it can make a preliminary judgment on whether the patient has complications, which provides important guidance for subsequent treatment.

2. Direct immunofluorescence

Non-gonococcal urethritis can also be examined by direct immunofluorescence, which requires the use of fluorescein to label specific chlamydia monoclonal antibodies, and then detect chlamydia antigens in the specimen. If there are chlamydia in the specimen, combined with antibodies, fluorescence can be found under a fluorescent microscope, and the number of chlamydia in the coating exceeds 10, which is positive.

3. Enzyme-linked immunosorbent assay

Enzyme-linked immunosorbent assay mainly uses a spectrometer to detect chlamydia antigens in the urogenital tract, and a color change can be found to be positive. Generally speaking, the results can be obtained within 24 hours, and its sensitivity can reach 60%-90%.

4. Cultivation of Chlamydia trachomatis

Chlamydia trachomatis is a parasite that lives in specialized cells and can only grow and reproduce in living cells. Mccoy cells and Hela229 cells are generally suitable for culturing Chlamydia, with a specificity of 99%-100%, and can be used as the gold standard for diagnosing Chlamydia trachomatis.

The above introduces four methods of checking non-gonococcal urethritis, which involve the patient's urethral health and are prone to frequent urination, urgency and pain. After the onset of the disease, attention should be paid to the inspection work, careful inspection, a clear diagnosis, and symptomatic treatment. Patients should pay attention to personal hygiene and should not have sexual intercourse during the onset of the disease to avoid cross infection.
