Diagnosing Liver Failure
Liver failure is a condition where the liver is unable to function properly, which disrupts its important functions in the body.
To diagnose liver failure, doctors may use a combination of examinations, screening tests, and procedures. These help confirm a diagnosis and determine the type, severity, or stage of liver failure. These tests include:
- Medical history: The doctor will ask about your medical history to understand your symptoms and any underlying conditions that could contribute to liver failure.
- Physical examination: During a physical examination, the doctor will examine your abdomen for any signs of tenderness or swelling in the liver area.
- Blood tests: Blood tests are commonly used to assess liver function. Liver function tests measure the levels of proteins and enzymes in your blood that can indicate how well your liver is functioning. Specific biomarkers such as liver enzymes (alanine aminotransferase and alkaline phosphatase) may be checked to assess liver toxicity or damage.
- Imaging tests: Techniques like ultrasound, CT scan, or MRI allow doctors to see the liver’s structure and spot any abnormalities or scarring. Ultrasound is usually the first choice for viewing liver tissue, while CT scans and MRIs offer more detailed insights into cirrhosis, liver lesions, tumors, blood clots in the portal vein, and fluid buildup (ascites).
- Liver biopsy: In some cases, a liver biopsy may be necessary to make or confirm a diagnosis of liver failure. During a biopsy, a small sample of liver tissue is taken for examination under a microscope. This can help identify factors contributing to the type, severity, or stage of liver failure.
- Additional tests: Depending on the specific situation and suspected causes of liver failure, additional tests such as viral hepatitis testing or genetic testing for conditions that can cause liver damage.
Doctors use these tests to diagnose liver failure by checking how well the liver works and spotting any issues with liver tissue. The results help identify the type (like toxic or viral), severity (mild to severe), and stage (early or advanced) of liver failure.
Specialists like gastroenterologists or hepatologists are needed for diagnosing and managing liver failure, as they have the expertise to treat liver-related conditions. If you have symptoms or concerns about your liver, it's important to see a healthcare professional for personalized advice.
