A leuko test is an examination of a woman’s vaginal secretions and is one of the most common gynecological examinations for women. It is also an important indicator of the vaginal self-cleaning function. Routine leukocyte examination includes cleanliness, leukocytes and red blood cells, trichomonas, mycobacteria, clue cells and miscellaneous bacteria. Under normal circumstances, a cleanliness level of 1-2 degrees is normal, but if the cleanliness level reaches 3 and 4 degrees, it is not normal and indicates an inflammatory infection. Leukocytes are an important indicator of inflammatory vaginal infections and an important basis for leukocyte cleanliness typing. Under normal circumstances, the leucocytes contained in the leucorrhoea under the microscope do not exceed 5. If there are more leucocytes, it means that the degree of inflammatory infection is also more serious. The examination of red blood cells is actually not very meaningful, mainly because it will touch the vaginal wall during the process of taking the leucocytes and cause a small amount of bleeding, so it is not very clinically significant. Trichomonas, mycobacteria and clue cells are tests that can reflect the type of vaginal inflammation suffered. If trichomonas is positive, it means trichomoniasis, mycobacteria is positive, and clue cells are positive, it means bacterial vaginitis. Stray bacteria are not present under normal circumstances, but can appear in cases where the vagina is less self-cleaning. After getting the report of the routine white belt test, you can also consult your clinical gynecologist if you are not sure about anything, and he or she will explain it to you in detail.
