What is the normal value for liver?

The liver is the most important organ in the human body, responsible for removing excess toxins and other wastes from the body. Therefore, the health of the liver has a great impact on the body. The health indicators of the liver can be judged by some test values. So, what are the normal values ​​of the liver for reference? Let’s take a look at the explanation below.

1. Alanine aminotransferase (ALT)

Normal reference value: 0-40IU/L

Clinical significance: It is of great significance for the diagnosis of liver parenchymal lesions and the observation of disease course changes.

Note: Blood should be collected on an empty stomach and the specimen should avoid hemolysis. Severe jaundice and turbid serum may also increase the result. Serum should not be frozen.

2. Aspartate aminotransferase (AST)

Normal reference value: 0-40IU/L

Clinical significance: Increased during acute myocardial infarction. It also often rises in cases of liver disease and other organ inflammation.

Note: The specimen should avoid hemolysis and serum should not be frozen.

3. Total protein (TP)

Normal reference value: 60-85g/L

Clinical significance: Understand the general situation of protein metabolism in the body. It has certain diagnostic and differential significance for liver and kidney damage, multiple myeloma, etc. Elevated total protein is often caused by blood concentration due to severe dehydration, shock, chronic adrenocortical insufficiency, etc.; decreased total protein is often caused by malnutrition and increased consumption (such as severe tuberculosis, hyperthyroidism, malignant tumors and chronic intestinal diseases), synthesis disorders (such as cirrhosis) and protein loss (such as nephrotic syndrome, ulcerative colitis, burns and blood loss).

Note: Blood should be collected on an empty stomach and the specimen should avoid hemolysis.

4. Albumin (ALB)

Normal reference value: 35-55g/L

Clinical significance: Albumin has a wide range of physiological functions, including nutritional value; maintenance of effective colloid osmotic pressure; transport of serum calcium, unconjugated bilirubin, free fatty acids, drugs, and thyroid hormones. The multiple physiological functions of albumin make it an important indicator for detecting liver diseases. Increased albumin is common in severe water loss, which leads to plasma concentration and increased albumin concentration. The decrease in albumin is basically the same as the total protein, especially in liver and kidney diseases.

Note: Blood should be collected on an empty stomach and the specimen should avoid hemolysis.
