The correct term for 3 plus lecithin is lecithin 3+, and lecithin 3+ found on a prostate fluid test is usually normal. Prostate fluid is an important test in prostate examination. Normally, the number of lecithin vesicles in prostate fluid is about 3 ~ 4, so lecithin 3+ is normal. When prostatitis occurs, the number of lecithin vesicles decreases and the number of white blood cells in the prostate fluid increases. The retention of prostate fluid is only used for the diagnosis and treatment of suspected chronic prostatitis. When prostatitis is in acute attack, it is not allowed to take prostate fluid through anal fingerprinting, otherwise it will easily lead to the spread of prostate inflammation and systemic infection. If the patient feels unwell, it is recommended to go to a regular medical institution for examination and standardized treatment under the guidance of a professional doctor, so as not to delay the condition.
