Quantification of coechobilinogen

A project for routine examination of stools that can assist in the diagnosis of jaundice. Astragalus is a common symptom and sign, which is caused by an increase in serum bilirubin concentration due to bilirubin metabolic disorders. Clinically, the sclera, mucous membranes, skin and other tissues are stained yellow. Basic Information Specialist classification: Digestive examination classification: feces / parasitic examination Applicable gender: whether men and women apply fasting: not fasting Tips: It is best for women to do fecal examinations to avoid menstruation, so as to avoid bloodshots. Normal value 68 to 473 μmol/d. Clinical significance Negative complete obstructive jaundice. Increase hemolytic anemia. Low results may be diseases: high results of cholestasis jaundice may be diseases: hemolytic anemia considerations 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.

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 Generally not.
