Fecal white blood cells

Fecal leukocyte testing is a project in the stool routine that helps understand digestion and absorption and assists in the diagnosis of digestive diseases. Not seen or occasionally seen in normal feces, mostly seen in mucus-bearing specimens, mainly neutral lobular granulocytes. Enteritis is generally less than 15 / HPF, dispersed. The specific amount is related to the severity and location of inflammation. In the small intestine, the number of white blood cells is small, evenly mixed in the feces, and it is not easily recognizable because the cells are partially digested. When colonic inflammation, such as bacterial dysentery, can be seen in the amount of white blood cells or piles of pus cells, it can also be seen that swallowing foreign bodies is not small phagocytic cells. Basic Information Specialist classification: Digestive examination classification: feces / parasitic examination Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: No or a few white blood cells are normal. Normal value: Number of white blood cells: 0-15/HP Above normal: Above 15/HP means there may be intestinal or parasitic diseases. negative: 0-15/HP. Positive: More than 15 / HP. Tips: Non-invasive examination, all suitable for the crowd. Normal value 0~ Occasionally, neutral lobular granulocytes. In the fecal microscopic examination of the cell reporting method, more than 10 high-powered field of view (referring to a certain cell) reported that every high power field (/HP) 10 fields only saw 1 occasional 10 fields of view sometimes missing, most common A minimum of 5 to 2 to 3 0 to 310 fields of view, and a maximum of 10 5 to 1010 fields of view have a cell number greater than 10 or more. In most of the 10 fields of view, the cells are evenly covered with a field of view and the full field of view cannot be calculated. Clinical significance Abnormal results: Leukocytes in the feces increase when there is inflammation in the intestines, and the number is related to the severity and location of inflammation. When the small intestine is inflamed, the number of white blood cells is small, evenly mixed in the feces, and it is not easily recognizable because the cells are partially digested. When the colon inflammation is like bacillary dysentery, white blood cells appear in large numbers, even full field of view, and degraded white blood cells can be seen. Pus cells with incomplete or broken edges and unclear nucleus can be seen. Allergic enteritis, intestinal parasitic diseases (such as amoebic dysentery or hookworm disease) are sometimes accompanied by Charcot-Leyden crystals in the stool, such as eosinophilic staining with Wright's stain Granulocytes. Need to check the crowd: Patients with suspected digestive system disease, patients with frequent abdominal pain. Low results may be diseases: gastroenteritis, cryptosporidiosis high results may be diseases: intestinal parasitic diseases, red peony, pediatric rotavirus enteritis, violent sputum, malaria, diarrhea, white diarrhea, traveler diarrhea, children Diarrhea, other Vibrio infection results may be disease: intestinal parasitic disease, red peony, pediatric rotavirus enteritis, violent convulsions, malaria, diarrhea, ferrets, traveller's diarrhea, pediatric diarrhea, other vibri infections Negative results may be diseases: gastroenteritis, cryptosporidiosis considerations Requirements for inspection: 1. The purpose of microscopy is to find pathological components such as cells. The film must be observed in full film, from top to bottom, from left to right, avoiding repetition, and observing at least 10 fields per smear during microscopy. Cell examination should be observed with a high power microscope. 2. Specimens should be inspected in a dry, clean container that does not absorb water. 3. Should be sent within 1 hour after defecation. Pre-inspection preparation: In order to make the stool examination results accurate and reliable, it is important to note that the stool sampling must be fresh. Some people took samples for one or two days before they were sent to the hospital laboratory. Because the cells were corrupt and could not reflect the real situation, the inspection would be meaningless. Unsuitable for the crowd: non-invasive examination, no suitable for the crowd. Inspection process The faeces with mucus and thick blood are about 2-3 grams (such as floccate if it is diluted with water), and it is contained in a sterile jar or sterile container. Use a cotton swab to pick up the feces and insert it into the transport medium or phosphate glycerol in pH 7.0 for inspection. The hospital performed smear, microscopic examination, search for white blood cells, recorded the total number of white blood cells in the field of view, and recorded the reference value. The white blood cells are colorless and spherical, have a nucleus, are larger than red blood cells, and have a diameter of 7 to 20 μm. Not suitable for the crowd Non-invasive examinations are all suitable for the population. Adverse reactions and risks This is a non-invasive examination, so the examination itself does not cause complications and harm.
