2023年4月12日 · ALT levels such as 60, 70, 80, 90, or 100 U/L are frequently discovered accidentally during routine laboratory investigations. In addition, mild elevations of ALT are often asymptomatic. The two most common causes of mildly elevated ALT are nonalcoholic fatty liver diseases (NAFLD) and medications.

2025年1月29日 · Alanine Aminotransferase (ALT) Test: What Does It Mean? What Is an ALT Blood Test? The alanine aminotransferase (ALT) test is a blood test that checks for liver damage. ALT used to be...

2024年4月26日 · Alanine aminotransferase (ALT) is an enzyme found inside liver cells. Liver enzymes, including ALT, help your liver break down proteins to make them easier for your body to absorb. When your...

2023年2月14日 · There are three main lab values that are commonly evaluated in relation to liver health: aspartate aminotransferase (AST), alanine transaminase (ALT) and alkaline phosphatase (ALP). AST and ALT are markers of liver cell injury.

Alanine Aminotransferase (ALT) is an enzyme found mainly in the liver, and its presence in the blood can suggest liver function and potential liver problems. This article will look at typical ALT levels throughout age groups, gender differences, and particular issues, including liver trace results, the cost of the LFT test, and ALT levels in ...

谷氨酸氨基转移酶或称丙氨酸氨基转移酶（alanine aminotransferase, ALT）在人体心脏、肝脏、肾脏等多个组织器官中存在，其中尤以肝脏含量最为丰富。 谷氨酸氨基转移酶主要存在于肝细胞中，是反映肝酶学变化的重要指标。 其指标水平与肝细胞受损程度保持着较高的一致性，即当发生肝细胞坏死及膜通透性增加时，谷氨酸氨基转移酶水平呈升高趋势。 谷氨酸氨基转移酶对于肝胆疾病诊断的专一性较高，因此可用于肝胆疾病的诊断及预后估计。 在除外肝外脏器病变的情况 …

2024年1月18日 · Alanine aminotransferase (ALT) is a liver enzyme, and high levels can indicate liver damage. Dietary and lifestyle steps to lower ALT levels may help the liver recover. This article looks at...

2020年12月18日 · 反映肝实质损害的指标，主要包括谷丙转氨酶（Alanine Transaminase, ALT）和谷草转氨酶 (Aspartate Aminotransferase, AST)。 ALT 是最常用的敏感指标，1% 的肝细胞发生坏死时，血清 ALT 水平可升高 1 倍，ALT 水平与肝脏损伤程度呈正比。 但当肝脏损伤发展到一定的严重程度，肝细胞大量坏死导致 ALT 枯竭，这时血液中的 ALT 反而降低，但是黄疸却持续升高，这种现象即所谓「酶胆分离」 [1]。 这一特殊情况更应引起临床工作者的注意。 AST …

2021年11月4日 · An alanine transaminase (ALT) blood test measures the amount of ALT in your blood. ALT levels in your blood can increase when your liver is damaged, so healthcare providers often use an ALT blood test to help assess the health of your liver.

Elevated alanine aminotransferase (ALT) values are seen in parenchymal liver diseases characterized by a destruction of hepatocytes. Values are typically at least 10 times above the normal range. Levels may reach values as high as 100 times the upper reference limit, although 20- to 50-fold elevations are most frequently encountered.
