The common laboratory tests of epididymal tuberculosis mainly include routine blood and urine examination, antacid bacillus culture test, tuberculin test, interferon-gamma release analysis and so on. 1. Routine blood and urine examination: routine blood examination reveals accelerated blood sedimentation; routine urine examination reveals elevated red blood cells and white blood cells in urine. 2. Antacid bacillus culture test: it is the gold standard test for the diagnosis of genitourinary tuberculosis at present. Generally, the anterior segment of urine is taken as the culture specimen, and the bacterial culture is carried out immediately after the specimen collection is completed. The methods of bacterial culture include the use of Roche medium for culture and the liquid detection system culture method. 3. Tuberculin test: This method is widely used to detect Mycobacterium tuberculosis and is a common screening method. This method is informative for patients such as adolescents, children and infants. 4. Interferon-gamma release assay: It is a blood test that can be used to detect the gamma-interferon produced by the body’s immune cells in response to Mycobacterium tuberculosis antigens, thus achieving the purpose of detecting the disease. For patients with epididymal tuberculosis, they should go to the relevant departments of regular hospitals as soon as possible, and under the guidance of specialized physicians, so as not to delay the condition and lead to adverse consequences.
