Fecal leukocytes of 0 to 2 are normal, which generally indicates that the condition is not serious, and should be analyzed by the doctor according to the patient’s individual situation. The normal value of fecal leukocytes is 0 to 3. The intestinal wall may also secrete a small amount of leukocytes, but not more than 3 is generally normal. To determine the severity of the disease, it is not possible to rely on a single test, but also need to be combined with symptoms, signs and other auxiliary tests to make a comprehensive judgment. If the fecal leukocytes exceed 3, suggesting the presence of intestinal inflammation, but also diarrhea, abdominal pain and other symptoms, stool may have mucus or even blood, can be seen in infectious and non-infectious diseases. Infectious diseases include bacterial enteritis and amoebic dysentery; non-infectious diseases include ulcerative colitis and Crohn’s disease. If the fecal leukocytes are normal, physiological diarrhea and functional constipation may also exist. General conditioning is the mainstay, and can be supplemented by symptomatic treatment. For the case of fecal leukocytes 0 to 2, it is recommended that the patient promptly consult a doctor to analyze the condition.
