How to read a biochemical test report

In general, a biochemical test report can be interpreted by examining indicators such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin, blood urea nitrogen (BUN), and creatinine. The specific analysis is as follows:

1. Alanine Aminotransferase (ALT): ALT is a specific enzyme found in the liver and serves as an indicator for assessing liver function. The normal range for ALT is 0–40 U/L.

2. Aspartate Aminotransferase (AST): AST is a protease involved in metabolism and biochemical transformations within the liver and is another marker of liver function. The normal range for men is 0–40 U/L, while for women it is 0–35 U/L. Elevated levels of both ALT and AST may indicate possible liver dysfunction.

3. Albumin: Albumin is an important plasma protein that helps maintain plasma osmotic pressure and reflects the body's nutritional status. Low albumin levels may suggest malnutrition, nephrotic syndrome, or similar conditions.

4. Blood Urea Nitrogen (BUN): BUN is the final product of protein metabolism in the body and serves as an indicator of glomerular filtration function. The normal range for adults is 3.2–7.1 mmol/L, while for infants and children it is 1.8–6.5 mmol/L.

5. Creatinine: Creatinine is a compound produced during the process of energy generation in muscles. The normal range for adult men is 0.50–1.50 mg/dL, and for adult women it is 0.80–1.20 mg/dL. If both creatinine and BUN levels are above normal, this may indicate renal insufficiency.

If any of these indicators are abnormal, it is recommended to visit a正规 hospital to determine the underlying cause and receive appropriate treatment.
