What tests should be done to check the liver?
The liver is an important metabolic and detoxification organ in the human body. Regular liver health checks are essential for the prevention and early detection of liver disease. The following is the liver examination-related content that has been hotly discussed on the Internet in the past 10 days, with structured data and suggestions compiled based on medical guidelines.
1. Core items of liver examination
| Check type | Check items | clinical significance | Reference price (yuan) |
|---|---|---|---|
| blood test | Five items of liver function | Evaluate enzyme activities such as ALT and AST | 80-150 |
| Hepatitis B two and a half | Screening for hepatitis B virus infection | 60-120 | |
| Hepatitis C antibodies | Screening for Hepatitis C | 50-100 | |
| Alpha-fetoprotein (AFP) | Liver cancer screening indicators | 70-150 | |
| Four items of liver fibrosis | Assess the degree of liver fibrosis | 200-400 | |
| Imaging examination | Liver B-ultrasound | Observe liver morphology and structure | 100-300 |
| CT/MRI | Fine assessment of liver disease | 500-2000 | |
| FibroScan | Non-invasive liver stiffness testing | 300-600 |
2. Examination recommendations for different groups of people
1.Healthy population screening: It is recommended to have a liver function test and liver B-ultrasound once a year, focusing on ALT, AST, GGT and other indicators.
2.Screening of high-risk groups(Hepatitis B carriers/long-term drinkers/obese people): Reexamination is required every 3-6 months, and additional items such as hepatitis B DNA testing and liver fibrosis assessment are added.
3.Patients with suspected liver disease: Carry out in-depth examinations such as enhanced CT and liver biopsy according to the doctor’s recommendations.
3. Recent hot discussions
1.New trends in fatty liver examination: The latest research shows that people with abnormal blood sugar metabolism are recommended to undergo insulin resistance testing.
2.Liver cancer early screening technology: Liquid biopsy technology (such as ctDNA testing) has become a recent medical hotspot, but the price is relatively high (about 3,000-5,000 yuan).
3.Inspection Precautions: Fasting requirements have triggered discussions. Most tests require fasting for 8-12 hours, but some new tests have removed this restriction.
4. Key points for interpretation of inspection results
| indicator | normal range | Exceptionally possible |
|---|---|---|
| ALT | 7-40U/L | liver cell damage |
| AST | 13-35U/L | Hepatitis/Myocardial Damage |
| total bilirubin | 3.4-20.5 μmol/L | Biliary obstruction/hemolysis |
| Albumin | 35-55g/L | liver function synthesis capacity |
5. Prevention Suggestions
1. Avoid drug abuse, especially common hepatotoxic drugs such as acetaminophen.
2. Control alcohol intake to no more than 25 grams per day for men and 15 grams for women.
3. Maintain a reasonable weight. It is recommended that the BMI be controlled between 18.5-23.9.
4. Get hepatitis B vaccine (uninfected persons) and complete the 0-1-6 months vaccination schedule.
Through regular and standardized liver examinations, more than 90% of liver diseases can be detected early. It is recommended to develop a personalized examination plan under the guidance of a doctor based on personal risk factors.
