The normal range of stool leukocytes is 0. Routine blood, urine and stool tests are all common tests performed during hospital examinations. Under normal circumstances the human body should have a normal range of 0 fecal leukocytes during a stool high magnification examination, and a few patients are found to have 0-1 leukocytes during the examination. This is mainly due to the fact that in some cases, the stool specimen is contaminated, or the urine is mixed in or the stool specimen is left for a longer period of time, which can affect the results of the test. Therefore, if you find that the index leukocyte is ≥2, it indicates that the patient may have an intestinal infection, and you should go to the hospital to improve the blood count or C-reactive protein test. At the same time, the clinical symptoms of the patient should be taken into account, such as diarrhea, fever, abdominal distension and other manifestations, to exclude intestinal infection. If there is an infection, it can be treated by rehydration or oral antidiarrheal drugs, such as montelukast.
