Lecithin vesicles 1+ leukocytes 1+ is a test in prostate fluid that means a significant decrease in the number of lecithin vesicles; an increase in leukocytes, which may be associated with prostatitis. Normal prostate fluid lecithin vesicles are abundant and evenly distributed all over the field of view, which is 4+, while lecithin vesicles 1+ means a significant decrease in the number of lecithin vesicles per high magnification field of view, which is unevenly distributed and accounts for only 1/4 of the field of view. leukocytes are negative if they are normally <10 per high magnification field of view, while 1+ suggests that the leukocytes are on the high side. Generally, when lecithin bodies are significantly reduced and leukocytes are increased, it may indicate chronic prostatitis, which needs to be actively treated under the guidance of a doctor.
