Serum arginylsuccinate lyase (ASAL)

Arginyl succinate lyase is an enzyme produced during the synthesis and metabolism of urea. It is most abundant in the liver and is present in small amounts in the small intestine and kidney. When the liver develops a lesion, it can break into the bloodstream with the liver cells. It is currently believed that the determination of arginyl succinate lyase in the diagnosis of hepatitis is comparable to that of transaminase. Basic Information Specialist classification: Digestive examination classification: biochemical examination Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: normal. Normal value: Serum arginyl succinate lyase: 0-0.9U/L Above normal: 1, severely elevated in viral hepatitis, primary liver cancer and so on. 2, moderate elevation seen in gallbladder cholangitis, infectious mononucleosis, congestive heart failure, chronic hepatitis, cirrhosis, Hodgkin's disease. negative: Positive: Tips: Do not eat too greasy, high-protein foods the day before the blood draw, avoid heavy drinking. The alcohol content in the blood directly affects the test results. After 8 pm on the day before the medical examination, you should start fasting for 12 hours to avoid affecting the test results. Normal value Reference value <0.9U/L. Clinical significance 1, severely elevated in viral hepatitis, primary liver cancer and so on. 2, moderate elevation seen in gallbladder cholangitis, infectious mononucleosis, congestive heart failure, chronic hepatitis, cirrhosis, Hodgkin's disease. High results may be diseases: viral hepatitis, primary liver cancer, chronic hepatitis, infectious mononucleosis, Hodgkin's disease considerations First, the precautions before blood draw 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. After 8 pm on the day before the medical examination, you should start fasting for 12 hours to avoid affecting the test results. 3, should relax when taking blood, to avoid the contraction of blood vessels caused by fear, increase the difficulty of blood collection. Second, should pay attention after blood draw 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 Immediately after venous blood collection, the test method was determined by colorimetry. Not suitable for the crowd no. Adverse reactions and risks Risk of infection: If you use an unclean needle, you may be at risk of infection.
