What diseases can be detected by the 7 liver function tests?

Generally, the seven-item liver test mainly includes liver function tests, liver enzyme profile, bilirubin measurement, and liver imaging examinations. These tests can help diagnose conditions such as viral hepatitis, gallstones, fatty liver, cirrhosis, and liver cancer. If experiencing any discomfort, it is recommended to seek medical attention promptly. The detailed explanations are as follows:

1. Viral Hepatitis

Viral hepatitis may be related to infections caused by bacteria, parasites, or other pathogens. Common symptoms include fatigue, loss of appetite, and nausea. The seven-item liver test may show elevated levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), indicating possible liver damage.

2. Gallstones

Gallstones may be associated with improper diet, lack of physical activity, and other factors. Common symptoms include skin itching and dark urine. As the condition worsens and affects bile excretion, it may damage the liver and lead to abnormal liver function. During the above-mentioned tests, abnormal liver function and bile duct dilation may be observed.

3. Fatty Liver

Fatty liver is usually associated with long-term high-fat diet, lack of exercise, and other factors. Patients may experience symptoms such as liver area pain and abdominal distension. The above tests may show fatty infiltration of the liver along with abnormal liver function.

4. Cirrhosis

Cirrhosis may be related to infections, alcohol consumption, staying up late, and other factors. These causes may damage liver function and cells, leading to symptoms such as abdominal swelling and liver area pain. During the seven-item liver test, elevated levels of total protein, albumin, and bilirubin may be observed, and imaging tests may show a shrunken and deformed liver structure.

5. Liver Cancer

Liver cancer is a type of malignant tumor, which may be associated with hereditary factors and unhealthy lifestyle habits. As the disease progresses, symptoms such as jaundice, generalized bone pain, and weight loss may occur. Liver imaging examinations may reveal solid liver lesions, with hard and poorly mobile nodules.

It should be noted that the above tests can only provide preliminary diagnosis and cannot confirm a diagnosis definitively. If abnormalities are detected, further diagnosis and analysis should be conducted based on accompanying symptoms and additional test results. Once the cause is identified, standardized treatment should be carried out under a doctor's guidance.
