Conjugated bilirubin (SDB, DBIL)

Tuberculosis bilirubin refers to the conversion of unconjugated bilirubin in hepatocytes, and binds to glucuronic acid to form bound bilirubin, also known as direct bilirubin. Determination of direct bilirubin is mainly used to identify the type of jaundice. The increase in serum-bound bilirubin indicates an obstacle to the excretion of bilirubin from the biliary tract after treatment and treatment with hepatocytes. Basic Information Specialist classification: Digestive examination classification: liver function test Applicable gender: whether men and women apply fasting: fasting Tips: Fasting for 12 hours before taking blood, taking fresh blood for inspection. Normal value Normal value: 0 to 7 μmol/L. Clinical significance Abnormal results: Increased in hepatocyte jaundice, obstructive jaundice, neonatal hyperbilirubinemia, Dubin-Johnson syndrome, Rotor syndrome. Total bilirubin and combined bilirubin increased, which was obstructive jaundice, total bilirubin and both bound and unbound bilirubin, which were hepatocellular jaundice. According to the ratio of combined bilirubin to total bilirubin, >35% is obstructive or hepatic jaundice, and the ratio <20% is hemolytic jaundice. High results may be diseases: post-hepatitis syndrome, pediatric acute cholecystitis considerations Before inspection: 1, do not eat too greasy, high-protein food the day before the blood, to avoid heavy drinking. The alcohol content in the blood directly affects the test results. 2. Fasting for 12 hours before taking blood, taking fresh blood for inspection. When checking: When you draw blood, you should relax your mind, avoid the contraction of blood vessels caused by fear, and increase the difficulty of blood collection. After inspection: 1. After blood is drawn, local compression is required at the pinhole for 3-5 minutes to stop bleeding. Note: Do not rub, so as not to cause subcutaneous hematoma. 2, the pressing time should be sufficient. There is a difference in clotting time for each person, and some people need a little longer to clotting. Therefore, when the surface of the skin appears to be bleeding, the compression is stopped immediately, and the blood may be infiltrated into the skin due to incomplete hemostasis. Therefore, the compression time is longer to completely stop bleeding. If there is a tendency to bleed, the compression time should be extended. 3, after the blood draw symptoms of fainting such as: dizziness, vertigo, fatigue, etc. should immediately lie down, drink a small amount of syrup, and then undergo a physical examination after the symptoms are relieved. 4. If there is localized congestion, use a warm towel after 24 hours to promote absorption. Inspection process The subject's blood is taken and immediately sent for testing, either by chemical or enzymatic methods. Not suitable for the crowd Unsuitable for the crowd: Newborns, jaundice, nausea and vomiting, abnormal liver function, yellow-stained person, and those without examination indications should not be detected. Adverse reactions and risks It generally does not cause complications and harm.
