Why should you check?
The liver is one of the most important organs in the human body, responsible for metabolism, detoxification, nutrient storage, and other functions. However, liver disease often has no obvious symptoms in the early stages, and by the time discomfort appears, it may have progressed to a more severe stage. Therefore, regular check-ups can help detect liver problems early and prevent their condition from worsening. According to the Hong Kong Health Bureau, liver cancer is one of the top 10 cancers in Hong Kong, with more than 1,800 new cases every year, most of which are related to hepatitis B or C infection. In addition, the prevalence of fatty liver disease is increasing year by year, and about 25% of adults suffer from fatty liver disease to varying degrees. These data show that testing is essential for the prevention and early diagnosis of liver disease.
Types of exams
Liver function tests (blood tests)
Liver function tests are blood samples that assess the health of your liver. Common indicators include:
- GOT(AST)とGPT(ALT): These two enzymes are mainly present in liver cells and are released into the bloodstream when damaged, so high values may indicate liver inflammation or damage.
- 胆紅素 (Bilirubin): Bilirubin is a product of the breakdown of red blood cells, which are processed and excreted by the liver. High bilirubin levels may indicate abnormal liver function or biliary obstruction.
- Alkaline phosphatase (ALP): Elevated ALP may be associated with biliary tract disease or bone problems.
- Albumin (albumin) and total protein (total protein): These two proteins are synthesized in the liver, and if their levels are too low, they may indicate liver dysfunction.
- 凝血機能 (PT, INR): The liver is responsible for the synthesis of clotting factors, and prolonged clotting may indicate abnormal liver function.
Imaging Tests
Imaging tests can visualize the structure and morphology of the liver, and common tests include:
- Abdominal ultrasound (): It is a convenient and rapid test method that does not use radiation, suitable for screening liver diseases. It is relatively cheap, ranging from around HK$800 to HK$1,500.
- Computed tomography (CT): CT can provide clearer images but carries the risk of radiation and is often used to further evaluate liver tumors and other lesions.
- Magnetic resonance imaging (MRI): MRI has a very high resolution of soft tissues and does not irradiate, but the examination time is long and expensive.
- 肝臟彈性掃描 (FibroScan): This test can assess the degree of liver fibrosis, which is especially important for people with chronic liver disease.
Viral hepatitis test
Viral hepatitis is one of the leading causes of cirrhosis and liver cancer, and common tests include:
- Hepatitis B surface antigen (HBsAg): positive indicates hepatitis B virus infection.
- Hepatitis B surface antibodies (anti-HBs): A positive indicates immunity to the hepatitis B virus.
- Hepatitis C antibodies (anti-HCV): Positive indicates possible hepatitis C virus infection and requires further confirmation.
Inspection Process
reserve
For liver examination, it is very important to choose the right medical institution. Both public and private hospitals in Hong Kong offer related services, but the waiting time and cost may vary. Tests in private hospitals are usually faster but more expensive. It is recommended to choose according to your needs and budget.
Preparation before the exam
Most liver function tests require 8 to 12 hours of hunger to avoid diet affecting the results. Imaging tests, such as abdominal ultrasounds, may also require fasting, and certain requirements must follow your healthcare provider’s instructions.
Review the process
Different test items have different precautions.
- blood test: Only a small amount of blood is drawn, the process is quick and painless.
- Abdominal ultrasound: During the examination, you will need to lie down, the doctor will apply the gel to the abdomen and scan the liver with a probe.
- CT or MRI: Injection of contrast agent may be required, and the examination should be stationary.
Interpreting the Report
After the examination is completed, you should consult a doctor to interpret the report. Based on the results, your doctor will assess your liver health and recommend further treatment or follow-up.
Who needs regular liver tests?
The following groups should have regular liver examinations:肝超聲波
- Hepatitis B and C carriers: These viruses can cause chronic hepatitis, cirrhosis, and even liver cancer.
- Patients with fatty liver: Fatty liver disease can develop into steatohepatitis and cirrhosis.
- Long-term drinkers: Alcohol damages liver cells and increases the risk of liver disease.
- Those who have a family history of liver cancer: Family history is an important risk factor for liver cancer.
- Other high-risk groups: For example, diabetics and obese people.
How to choose the right liver test?
When choosing a liver test, you should consider your health and risk factors. For example, hepatitis B carriers should undergo regular liver function tests and liver ultrasounds. Patients with fatty liver disease may need to undergo FibroScan to assess the extent of fibrosis. It is recommended to consult a doctor and choose the most suitable test items based on the advice of a specialist.
Precautions after a liver test
After the examination, you should pay attention to your diet and lifestyle, avoid drinking alcohol and eating high-fat foods, and maintain regular exercise. If the test results are abnormal, follow your doctor’s recommendations for treatment or regular follow-up.肝臟超聲波價錢
