Whether a plus sign of lecithin vesicles is serious or not needs to be judged in combination with symptoms and other test results. The lecithin somes are a substance secreted by normal male prostate fluid, when prostatitis occurs, the secretion of lecithin somes decreases, therefore, it is mainly used to detect prostatitis, but the amount of its quantity is not proportional to the severity of prostatitis. Normal lecithin bodies are 3 plus or more, when lecithin bodies are a plus, with prostate fluid white blood cells rising significantly, or there is obvious frequency of urination, urinary urgency, lower abdominal pain and discomfort, and even fever, it means that the condition is more serious. If there is no obvious urinary frequency, lower abdominal pain and other symptoms of prostatitis, no obvious rise in prostate white blood cells, despite the lecithin microsomes a plus sign, the decrease is obvious, but the general condition is not very serious. If the examination found abnormalities, should go to the regular hospital, follow the physician’s advice to deal with, do not use private medication, so as not to cause danger.
