Tests reflecting the excretory function of the liver

The test that reflects the function of liver excretion is to detect the ability of the liver to excrete certain endogenous (bilirubin, bile acid, etc.) or exogenous (dyes, drugs, etc.) high ingested substances. Be careful not to take the drug before the test, because some drugs will increase the burden on the liver, causing temporary damage to the liver function, which will lead to the accuracy of the liver function test results. Pay attention to ensure adequate sleep before the examination, do not exercise vigorously. Basic Information Specialist classification: Digestive examination classification: liver function test Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Common in hemolytic jaundice. Normal value: TBILI (total bilirubin): 3.0-20.0umol/L DBILI (direct bilirubin): 1.7-8.0umol/L IBIL: 3.4-13.5umol/L Above normal: Common in severe hepatitis. negative: Positive: Tips: Do not eat before the test, blood test requires fasting, fasting time is generally 8 to 12 hours. Normal value TBILI (total bilirubin) has a normal value of 3.0-20.0 umol/L. The normal value of DBILI (direct bilirubin) is 1.7-8.0 umol/L. The normal value of IBILI (indirect bilirubin) is 3.4-13.5 umol/L. Clinical significance Abnormal results Total bilirubin greater than 17.1μmd / L is a case of jaundice. If bilirubin is progressively elevated with ALT, it is called enzymatic biliary separation, suggesting that the condition is aggravated and there is a possibility of switching to severe hepatitis. Hemolytic jaundice generally TBil <85μmol / L, direct bilirubin / total bilirubin <20%; hepatic jaundice generally TBil <200μmol / L, direct bilirubin / total bilirubin > 35%; obstructive jaundice Generally TBil>340μmol/L, direct bilirubin/total bilirubin>60%. Need to check patients with viral hepatitis, drugs or alcohol caused by toxic hepatitis, hemolytic jaundice, pernicious anemia, paroxysmal hemoglobinuria and neonatal jaundice, internal bleeding and other patients. Low results may be diseases: high hepatitis results may be diseases: hemolytic jaundice precautions Taboo before inspection: 1. Be careful not to take the drug before the test, because some drugs will increase the burden on the liver, causing temporary damage to the liver function, which will lead to the accuracy of the liver function test results. 2. Pay attention to ensure adequate sleep before exercise, do not exercise vigorously, which may cause elevated transaminase, thus affecting the test results. 3. You must not drink alcohol the day before. Drinking alcohol will cause an increase in transaminase and affect the test results. 4. It is best not to eat too greasy, too spicy food the night before. Taboo when checking: 1. Can not eat before the examination, blood test requires fasting, fasting time is generally 8 to 12 hours. 2. Check the morning of the day as far as possible not to exercise or strenuous exercise, if the exercise should go to the hospital after a quiet rest for 20 minutes before taking blood test. Inspection process 6 ml of venous blood was drawn, and the tube was used to check the concentration of total bilirubin, direct bilirubin and indirect bilirubin. Not suitable for the crowd 1. Patients who have taken contraceptives, thyroid hormones, steroid hormones, etc., because the drug will increase the burden on the liver, may affect the results of the examination, and prohibit patients with a history of drug administration in the near future. 2, special diseases: patients with hematopoietic function to reduce disease, such as leukemia, various anemia, myelodysplastic syndrome, etc., unless the examination is essential, try to draw less blood. Adverse reactions and risks 1, subcutaneous hemorrhage: due to pressing time less than 5 minutes or blood draw technology is not enough, etc. can cause subcutaneous bleeding. 2, discomfort: the puncture site may appear pain, swelling, tenderness, subcutaneous ecchymosis visible to the naked eye. 3, dizzy or fainting: in the blood draw, due to emotional overstress, fear, reflex caused by vagus nerve excitement, blood pressure decreased, etc. caused by insufficient blood supply to the brain caused by fainting or dizziness. 4. Risk of infection: If you use an unclean needle, you may be at risk of infection.
