AST是一种I类磷酸吡哆醛依赖的酶,存在于细胞质中的为AST1,存在于线粒体中的为AST2。编码可溶性AST1的基因位于第10号染色体(10q24.2),编码线粒体AST2的基因位于16号染色体(16q21)。 AST主要分布在心肌,其次是肝脏、骨骼肌以及肾脏中。最初,AST被用于心肌损伤的诊断具有一定的价值,...
AST/ALT Ratio Test to Detect Liver Function When Are Tests Required? Lesson Summary Frequently Asked Questions What does it mean when ALT and AST are high? If your AST and ALT levels are above the upper limit of normal (ULN), you are likely experiencing symptoms of abdominal pain, darkene...
this denotes alcoholic liver disease. And if the ratio is between 1.4 and 2.0, it suggests cirrhosis. Interestingly enough, the severity of cirrhosis is measured by the level of the ratio, implying that patients of cirrhosis with a high AST:ALT ratio would probably...

BARD score was calculated by summing up three variables: BMI > 28 for 1 point, AST/ALT ratio > 0.80 for 2 points, and diabetes for 1 point. It is demonstrated that score values of 0 or 1 would have a high NPV for advanced fibrosis [21], and a score of 2 to 4 is correlated wit...
(rs188273166), proportional with the observation of increased ALT and AST (OR = 1.47); however, owing to the small sample size of carriers and liver disease cases, we are underpowered to confidently determine whether this high point estimate is due to chance (although the 95% CI from ...

AST:天冬氨酸转氨酶;ALT:谷丙氨酸转氨酶;CHB:慢性乙型肝炎;HBV:乙型肝炎病毒;HBeAg:乙型肝炎e抗原;NK:自然杀伤细胞;qHBsAg:乙型肝炎表面抗原定量;ULN:正常上限。 除治疗组肝脏炎症分级较高外,两组间基线参数无显著性差异。治疗组基线HBV DNA为7.99lgIU/ml,对照组为8.53lgIU/ml。治疗组基线ALT为43U/L,对照组为...
Too high AST ALT ratio with low levels of AST and ALT. Can be caused by factors located outside of the liver, such as hemolysis (the breakdown of the red blood cells), and muscle or thyroid gland diseases. Too Low AST ALT ratio - check the section below. The interpretation of an ele...
AST Often used alongside ALT to assess liver health. The ratio of ALT to AST helps diagnose certain liver conditions. 12 ALT A key indicator of liver health and function. High ALT levels may hint at underlying liver diseases. 3 AST Abbreviation for Aspartate Aminotransferase. Elevated AST levels...
