Fecal red blood cells

Fecal red blood cell examination is a routine routine of stool, which can understand digestion and absorption functions and help diagnose digestive diseases. Red blood cells have no red blood cells in normal feces. Inflammation or bleeding in the lower part of the intestine may occur if dysentery, ulcerative colitis, colon cancer, rectal polyps, acute trematode disease, etc. The fresh red blood cells in the feces are grassy yellow, slightly refraction discs. Bacterial dysentery is less red blood cells than white blood cells, polydisperse and normal morphology; amoebic dysentery has more red blood cells than white blood cells, and many piles exist and are broken. Basic Information Specialist classification: Digestive examination classification: feces / parasitic examination Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Normal value: no Above normal: negative: Negative is normal. Positive: Fecal red blood cell positive suggests a possibility of lower gastrointestinal bleeding. Tips: Please avoid digging the part of the toilet urine and tap water when collecting, and do not place the feces directly on toilet paper or paper towels. Normal value Negative is normal. Clinical significance Abnormal results: When the intestinal mucosa is inflamed, erosive or hemorrhagic, red blood cells can be seen in the feces of diseases such as dysentery, ulcerative colitis, and colon cancer. When the amoebic dysentery occurs, there are more red blood cells than white blood cells in the feces, which appear in piles and are destroyed. Bacterial dysentery feces are mainly white blood cells, and red blood cells are often scattered. Need to check the crowd: Suspected patients with intestinal parasite infection, feces were dark red patients. Positive results may be diseases: lower gastrointestinal bleeding, gastrointestinal bleeding, ulcerative enteritis, bacterial enteritis, proctitis, chronic enteritis, enteritis, dampness and phlegm, ischemic enteritis considerations Requirements for inspection: 1. Please avoid digging the part of the toilet urine and tap water when collecting, and do not place the feces directly on toilet paper or paper towels. 2, when doing chemical occult blood test, should be fasted meat and animal blood food in the first three days and banned iron and vitamin C. Preparation before inspection: 1. Ingestion of drugs that cause gastrointestinal bleeding, such as aspirin, corticosteroids, non-steroidal anti-inflammatory drugs, can cause false positives in chemical occult blood tests, while intake of large amounts of vitamin C can cause false negatives in occult blood tests, chemical examination Upper gastrointestinal bleeding (stomach, duodenum, etc.) is reliable, and the immune method is mainly suitable for the examination of bleeding in the lower digestive tract (small intestine, large intestine). 2. If you use the immunological method to detect fecal occult blood, you do not need to limit the type of diet. 3, because infants and young children are not easy to get a sufficient amount of samples at a time, if you need to collect in separate parts, please temporarily store the samples in the refrigerator to avoid bacterial growth. Inspection process The fecal occult blood test means that when the amount of gastrointestinal bleeding is small, the naked eye cannot see blood in the feces, and a small amount of red blood cells in the feces are destroyed. Detect a small amount of blood components in the stool. Multiple, persistent occult blood test positive, suggesting chronic bleeding in the digestive tract. Not suitable for the crowd This test is a non-invasive test, so there is no contraindication. Adverse reactions and risks This test is a non-invasive test and the test itself does not present complications and hazards.
