glutathione S-transferase

Glutathione S-transferase (GST) GST is a group of enzymes involved in liver detoxification. The enzyme is mainly present in the liver and is present in trace amounts in tissues such as the kidney, small intestine, testis, and ovaries. Since the liver cell is rich in GST, when the liver cells are damaged, the enzyme is rapidly released into the blood, resulting in an increase in serum GST activity. 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: Glutathione S transferase: 0-21U/L Above normal: In acute hepatitis, CST changes were positively correlated with ALT; in severe hepatitis and chronic hepatitis, GST was significantly higher than those with elevated ALT; in patients with severe hepatitis, serum GST was significantly elevated, most of them were 5-8 times of normal; GST in patients with acute severe hepatitis sometimes rises to tens of times normal. negative: Positive: Tips: After 8 pm on the day before the medical examination, you should start fasting for 12 hours, so as not to affect the test results. Normal value Enzyme activity method, serum GST <21U / L. Clinical significance Abnormal result In acute hepatitis, CST changes were positively correlated with ALT; In severe hepatitis and chronic hepatitis, the increase in GST was significantly higher than in those with elevated ALT; In patients with severe hepatitis, serum GST is significantly elevated, mostly 5 to 8 times that of normal people; GST in patients with acute severe hepatitis sometimes rises to tens of times normal. Need to check the population suspected of hepatitis or the determination of hepatitis. High results may be diseases: chronic hepatitis precautions 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. 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. 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. Inspection process Inspection method: draw blood. Not suitable for the crowd no. Adverse reactions and risks no.
