Leukocytosis means the presence of a small number of white blood cells in the test performed, suggesting that a mild inflammation or chronic infection may be present. Leukocytes are often found in routine urine, fecal, leukorrhea, and semen tests. If there are a few leukocytes in the urine routine, it suggests that there may be a slight urinary tract infection, or chronic cystitis, pyelonephritis, etc. If there are a few leukocytes in the fecal routine, there may be an intestinal infection. If there are a few leukocytes in the leukorrhea routine, it suggests that there may be pathogenic infections, but if there is no increase in leukorrhea, color abnormalities, odor and other inflammatory manifestations, it does not necessarily require treatment. The presence of a few leukocytes in the test program, the specific condition judgment and the need for treatment, need to consult a doctor, combined with other tests and clinical symptoms to consider.
