Introduction

Transaminases are a group of enzymes found in various tissues of the human body, mainly in liver cells, as well as in myocardial, skeletal muscle, kidney, and other tissues. When these tissues are damaged, transaminases may be released into the bloodstream, leading to elevated levels of transaminases in the blood. Therefore, elevated transaminase levels can be caused by various factors, including—but not limited to—viral hepatitis.

Generally speaking, elevated transaminase levels are not necessarily indicative of hepatitis. If discomfort symptoms occur, it is recommended to seek timely medical consultation at a hospital for standardized treatment under the guidance of a physician. Detailed analysis is as follows:

Transaminases are one type of several enzymes in the human body. They mainly exist in liver cells, as well as in tissues such as the myocardium, skeletal muscles, and kidneys. When these tissues are damaged, transaminases may be released into the bloodstream, leading to elevated levels of transaminases in the blood. Therefore, elevated transaminase levels can be caused by various factors, including—but not limited to—liver inflammation. Additionally, unhealthy lifestyle habits, such as chronic sleep deprivation, excessive fatigue, high levels of mental stress, and excessive alcohol consumption, may also damage the liver and cause elevated transaminase levels. Moreover, certain medications can also cause liver damage, resulting in increased transaminase levels.

When elevated transaminase levels are detected, hepatitis should not be diagnosed directly. A comprehensive evaluation combining the patient's medical history, symptoms, clinical signs, and other test results is necessary. Meanwhile, patients with elevated transaminase levels are advised to actively adjust their lifestyle habits, avoid excessive fatigue and unhealthy dietary practices, which is beneficial for recovery.

What are the effects of excessively high transaminase levels?

Elevated transaminase levels can have multiple effects on the body, including impaired liver function, reduced hepatic metabolic capacity, increased risk of cardiac damage, coagulation disorders, and decreased immune function. It is important to maintain a healthy lifestyle, including a balanced diet and reduced intake of high-fat, high-sugar, and high-salt foods, to help preserve normal liver metabolic function.

Is normal transaminase equivalent to normal liver function?

Under normal circumstances, normal transaminase levels do not necessarily indicate normal liver function. Some liver diseases may not lead to a significant increase in transaminase levels in the early stages, such as fatty liver disease and autoimmune liver disease. Therefore, even with normal transaminase levels, the possibility of liver disease cannot be completely ruled out. If liver problems are suspected, timely medical consultation is recommended, along with further examinations and treatment as directed by a physician.

How serious is an ALT level of 700 U/L?

In general, transaminases are key indicators of liver function and mainly include alanine aminotransferase (ALT) and aspartate aminotransferase (AST). The normal range is typically 0–40 U/L; a transaminase level above 700 U/L represents a significant elevation. Whether this is serious depends on the specific circumstances. If related symptoms are present, immediate medical attention is recommended.

Is alanine aminotransferase a transaminase?

Under normal circumstances, alanine aminotransferase is one type of transaminase. When undergoing an alanine aminotransferase test, it is important to avoid strenuous exercise, alcohol consumption, and staying up late before the test, as these factors may affect the accuracy of the test results. In daily life, maintaining a regular sleep schedule and a balanced diet can help support normal liver function and keep alanine aminotransferase levels within the normal range.
