丙胺酸转胺酶(ALT)是一种主要存在于肝脏细胞中的酶,常用于血液检测以评估肝功能或诊断肝脏疾病。

用法要点

句型搭配

ALT通常作为名词使用,在医学语境中常与表示测量、升高或降低的动词搭配,用于描述检测结果或临床状况。

• measure ALT levels
• elevated ALT
• ALT is normal

介词用法

在描述ALT与身体部位或疾病关系时,常用介词'in'表示位置(如在肝脏中),或用'for'表示检测目的(如用于肝功能检查)。

• ALT in the liver
• test for ALT
• ALT for liver function

语域说明

ALT是高度专业化的医学术语,主要用于医疗、科研和健康管理领域,日常对话中较少使用,除非讨论健康检查结果。

• clinical ALT testing
• ALT in medical reports
• discuss ALT results

基础例句

My doctor said my ALT levels are a bit high, so I need to cut back on alcohol.

医生说我的丙胺酸转胺酶水平有点高,所以我需要减少饮酒。

During my annual check-up, they always test for ALT to check my liver health.

在我每年的体检中,他们总是检测丙胺酸转胺酶来检查我的肝脏健康。

If your ALT is normal, it usually means your liver is functioning well.

如果你的丙胺酸转胺酶正常,通常意味着你的肝脏功能良好。

高级例句

The study found that elevated ALT levels were correlated with increased risk of metabolic syndrome in patients.

研究发现,患者丙胺酸转胺酶水平升高与代谢综合征风险增加相关。

In clinical practice, ALT is commonly measured alongside AST to differentiate between hepatic and cardiac issues.

在临床实践中,常同时测量丙胺酸转胺酶和天冬氨酸转胺酶,以区分肝脏和心脏问题。

The new drug trial showed a significant reduction in ALT activity, indicating potential hepatoprotective effects.

新药物试验显示丙胺酸转胺酶活性显著降低,表明其可能具有肝保护作用。

常见错误

❌ 错误:My ALT is high because I eat too much fat.
✓ 正确:My ALT is high, which may be related to my diet high in fat.

错误用法直接因果关联,但ALT升高可能由多种因素引起;正确用法更准确,使用'可能相关'来表述,符合医学语境的不确定性。

❌ 错误:I need to check my ALT enzyme in the hospital.
✓ 正确:I need to have my ALT levels tested at the hospital.

错误用法中'check my ALT enzyme'不够自然,且'enzyme'在此冗余;正确用法使用'tested'和'levels'更符合英语母语者习惯,强调检测行为。

近义词辨析

AST (aspartate aminotransferase)

AST也是转胺酶,但主要存在于心脏和肌肉细胞,常与ALT一起检测以区分肝脏损伤和其他问题;ALT更特异性指示肝脏状况。

While both ALT and AST can be elevated in liver disease, a higher ALT/AST ratio often suggests alcoholic liver disease.

liver function test

肝功能测试是一个 broader term,包括ALT、AST、胆红素等多种指标;ALT是其中 specific 的一项,专注于转胺酶活性。

The liver function test showed abnormal results, particularly in the ALT component, indicating possible hepatitis.
