Aspartate aminotransferase (AST) and alanine aminotransferase (ALT), also known as ‘aspartate aminotransferase,’ also has an old name, which is called ‘glutamic-oxaloacetic transaminase.’ It exists in many parts of the body, such as the heart, kidneys, liver, muscles, and other tissues. Then, what are the causes of its lower levels? What are the causes of slightly lower levels of blood cell aspartate aminotransferase (AST) and alanine aminotransferase (ALT)?

1. Aspartate aminotransferase (AST) and alanine aminotransferase (ALT)

1. It is present in every tissue of the human body to a certain extent, with a very wide range, but its levels vary in each tissue. The main tissues where it is generally distributed are the heart, liver, kidneys, muscles, etc.

2. It not only belongs to a type of aminotransferase but also serves as a cellular function enzyme. Since it generally exists in the nuclei and mitochondrial matrix of tissues, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) are similar to about 80% of which are in the membrane proteins, so it is still a cellular function enzyme.

3. If a healthy person is in a normal state, the normal range of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) from the liver is generally 0-40U/L (corporation).

Causes of fluctuations in aspartate aminotransferase (AST) and alanine aminotransferase (ALT)

Its levels can reflect the condition of liver necrosis, and checking the levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) is very accurate in determining whether a patient has liver cirrhosis, liver fibrosis, or liver cancer.

1. Causes of slightly lower aspartate aminotransferase (AST) and alanine aminotransferase (ALT)

In clinical medicine, generally speaking, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) at slightly lower levels are not a major concern. They may be slightly lower in the morning or after exercise.

2. Causes of elevated aspartate aminotransferase (AST) and alanine aminotransferase (ALT)

Generally, higher levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) indicate liver damage. Under such conditions, it is easy to suffer from diseases such as hepatitis B, liver cirrhosis, fatty liver, and alcoholic liver. However, if the patient has engaged in excessive exercise, drinking alcohol, or staying up late before the examination, it may cause an increase in aspartate aminotransferase (AST) and alanine aminotransferase (ALT).

If the aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels are slightly lower than usual, there is generally no major problem. However, it is still necessary to pay attention to rest, intake of a certain amount of nutrients, and regular exercise to enhance the body’s resistance.
