In addition to symptoms such as swelling, itching, and increased secretion, balanitis has many pathogenic bacteria, such as mold, bacillus, staphylococcus, mycoplasma, chlamydia, etc. It needs to be combined with blood, urine, secretion, and other related tests to identify specific causes and targeted treatment. The blood sampling test for balanitis is mainly to check the blood routine to see whether the white blood cells are increased. If the white blood cells are increased to a very high degree, it means that there is bacterial infection. At this time, antibacterial treatment is carried out according to the different bacteria. The course of treatment is long, and it must be standardized. In order to prevent cross infection, it is best to avoid sexual life during the unhealed period, and be responsible for the other half.
