The bilirubin in normal human bile is decomposed into faecal tract by the bacteria at the end of the ileum and the colon. Some of it is reabsorbed into the intestinal hepatic circulation by the intestine, and most of it is oxidized into sessile biliary in the colon and excreted with feces. The faecal biliary is also known as urinary biliary and bilirubin. The bilirubin in normal human bile is decomposed into feline by the bacteria at the end of the ileum and the colon. Some of it is reabsorbed into the intestinal hepatic circulation by the intestine, and most of it is oxidized into fecal biliary tract in the colon and excreted with feces. After exposure to air, it becomes sucralin, which is brownish red, so the stool is often reddish.Basic Information
Specialist classification: Digestive examination classification: feces / parasitic examination
Applicable gender: whether men and women apply fasting: not fastingReminder: After the specimen is collected, it should be checked within 1 hour. Otherwise, it may be destroyed due to the influence of PH gel digestive enzymes. Normal value
75-350 mg/100 g of feces (Ehrlich method).Clinical significance
(1) Increased hemolytic jaundice, paroxysmal nocturnal hemoglobinuria, pernicious anemia, thalassemia, aplastic anemia, intra-tissue hemorrhage and other red blood cell destruction.
(2) reduce obstructive jaundice.
The principle of fecal gallbladder in hepatic jaundice can be increased or decreased, depending on the intrahepatic obstruction. The original test of faecal biliary has certain value for the identification of jaundice type.
Need to check the crowd:
Patients with abnormal bleeding symptoms.Low results may be diseases: neonatal congenital biliary atresia results may be high disease: hemolytic jaundice, congenital pure red blood cell aplastic anemia precautions
Preparation before inspection:
1, women do stool examination is also best to avoid menstruation, so as not to mix blood.
2. After the specimen is collected, it should be checked within 1 hour. Otherwise, it may be destroyed due to the influence of PH gel digestive enzymes.
Requirements for inspection:
1. Because infants and young children are not easy to get enough samples at one time, if they need to be collected separately, please temporarily store the samples in the refrigerator to avoid bacterial growth.
2. Normal stools are yellow or brownish yellow because they contain sessile bilirubin.
Not suitable for people:
There is no suitable crowd for the time being.Inspection process
Fecal gallbladder in feces is significantly increased in hemolytic jaundice due to the large amount of bilirubin discharged into the intestine by bacteria; obstructive jaundice is significantly reduced due to less bile sputum discharged into the intestine; hepatocytes The principle of fecal gallbladder in jaundice can be increased or decreased, depending on the condition of intrahepatic obstruction. The qualitative or quantitative determination of fecal gallbladder has certain value for the identification of the type of jaundice. Ehrlich method is used for qualitative or quantitative methods. The red compound is formed after the melon, and the ratio of the depth to the original amount of the fecal gallbladder is normal. The amount of biliary in the normal human per 100 g of feces is 75-350 mg. Below or above the reference value can be diagnosed as obstructive or hemolytic jaundice.Not suitable for the crowd
Generally no taboos.Adverse reactions and risks
