Advanced Liver Tests and Diagnosis for Hepatology Diseases

At PACE Hospitals, we utilize advanced diagnostic tools to accurately assess liver health and diagnose a wide range of hepatological conditions. Our liver experts employ advanced techniques and molecular testing to ensure precise diagnosis and personalised treatment plans for each patient. These tests help us identify liver diseases early and guide effective management strategies.

Blood Tests

Complete Blood Count (CBC)

A CBC measures red blood cells, white blood cells, and platelets. In liver disease, low platelet levels may indicate portal hypertension caused by scarring of the liver. If anemia is present, it can be due to chronic liver disease, internal bleeding, or nutritional deficiencies, which are linked to liver dysfunction. Elevated or low levels of white blood cells may point toward infection or inflammation.

Liver Function Tests (LFT)
Liver function tests measure enzymes, proteins, and substances produced or processed by the liver, such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), bilirubin, and albumin. When liver cells are damaged or inflamed, these enzymes leak into the blood and their levels rise. Abnormal LFT results help doctors identify liver injury, inflammation, bile flow blockage, or reduced liver function. Patterns in these values also help differentiate between acute liver damage, chronic liver disease, and advanced liver failure.

Viral Hepatitis Panel

A viral hepatitis panel is a blood test used to detect infections caused by hepatitis viruses. It identifies viral antigens, antibodies, or genetic material that indicate current infection, past exposure, or immunity. This test is used to diagnose viral causes of liver inflammation, which are common reasons for elevated liver enzymes.

Prothrombin Time (PT) / International Normalised Ratio (INR)
PT and INR assess how quickly blood clots, which depends on clotting factors made by the liver. When liver function declines, production of these clotting proteins decreases, leading to prolonged PT/INR values. This test is especially useful for evaluating the severity of liver disease and detecting liver failure. A rising INR often indicates worsening liver function and helps doctors assess prognosis and the need for urgent medical intervention.

Autoimmune Liver Markers
This test helps to detect specific antibodies that appear when the immune system mistakenly attacks liver cells. These markers aid in diagnosing autoimmune-related liver diseases by confirming immune-mediated inflammation rather than alcohol or virus-related causes. Identifying these antibodies is important because autoimmune liver diseases often require long-term immunosuppressant treatment.

Iron Studies
Iron studies measure iron levels, ferritin, and iron-binding capacity in the blood. Excess iron accumulation can damage liver cells and lead to chronic liver disease. Abnormal iron levels help doctors identify iron overload disorders that may cause liver inflammation and scarring.

Genetic Testing

Genetic testing identifies inherited conditions that affect liver function by analysing specific genes. It helps diagnose liver diseases caused by abnormal metabolism or storage of substances within liver cells. These tests are especially useful in patients with unexplained liver disease, early-onset symptoms, or a family history of liver disorders.

Imaging Tests

Ultrasound Abdomen
This scan uses sound waves to create images of the liver and nearby organs. It helps detect changes in liver size, fatty deposits, cysts, tumors, gallstones, and fluid accumulation in the abdomen. This test is often the first imaging step when liver disease is suspected because it is safe, painless, and quick.

Doppler Ultrasound
Doppler ultrasound evaluates blood flow within liver vessels, including the portal vein and hepatic veins. It helps identify reduced or reversed blood flow, which can occur in advanced liver disease and portal hypertension. This test is useful for detecting vascular problems, blood clots, and complications related to liver scarring.

CT Scan Abdomen
A CT scan provides detailed cross-sectional images of the liver using X-rays. It helps identify liver tumors, abscesses, bleeding, fatty changes, and structural damage. CT scans are especially useful for detecting complications of chronic liver disease and for cancer staging.

FibroScan (Transient Elastography)
FibroScan is a non-invasive test that measures liver stiffness using sound waves. Increased stiffness indicates liver fibrosis or scarring. This test helps assess the severity of chronic liver disease and monitor disease progression over time. FibroScan reduces the need for liver biopsy in many patients and is widely used to detect early liver damage before symptoms appear.

Upper Gastrointestinal Endoscopy
Upper GI endoscopy is commonly used in hepatology to detect complications of chronic liver disease rather than liver damage itself. It helps identify enlarged veins in the food pipe or stomach caused by portal hypertension, a common result of liver scarring.

Endoscopic Retrograde Cholangiopancreatography (ERCP)
ERCP is a specialised procedure used in hepatology to diagnose disorders of the bile ducts that affect liver function. It helps identify bile duct blockages, narrowing, stones, leaks, or tumors that cause jaundice and abnormal liver tests. ERCP provides detailed imaging of bile flow and allows doctors to confirm the cause of cholestatic liver disease.

Invasive Tests

Liver Biopsy
A liver biopsy involves taking a small tissue sample from the liver for microscopic examination. It helps doctors directly assess liver inflammation, scarring (fibrosis), fat buildup, and abnormal cell growth. This test is beneficial when blood testing and imaging cannot determine the cause or stage of liver disease. Biopsies are used to confirm diagnosis, determine disease severity, and guide therapy options in chronic and complex liver conditions.

Ascitic Fluid Analysis
This analysis examines fluid collected from the abdomen in patients with ascites, which is a common complication of advanced liver disease. The test helps determine whether fluid buildup is due to liver-related portal hypertension or other causes. It also detects infection, inflammation, or cancer cells. Ascitic fluid analysis is essential for identifying serious complications and guiding urgent treatment in patients with decompensated liver disease.

Hepatic Venous Pressure Gradient (HVPG)
HVPG measures the pressure difference within liver blood vessels to assess portal hypertension. Increased pressure indicates significant liver scarring and impaired blood flow. This test helps diagnose advanced liver disease, assess severity, and predict complications such as bleeding from enlarged veins.

Additional Diagnostic Approaches

Liver Elastography (Other than FibroScan)
This is a non-invasive imaging technique that measures the stiffness of the liver, which can indicate the presence of liver fibrosis or cirrhosis. It works by sending a low-frequency wave through the liver, and the speed at which the wave travels helps determine the degree of stiffness. Stiffer liver tissue typically suggests more advanced liver disease, such as fibrosis or cirrhosis, and can help assess the severity of liver damage. 

Liver-Specific Imaging (MRI or MRCP)
Magnetic Resonance Imaging (MRI) and Magnetic Resonance Cholangiopancreatography (MRCP) are modern imaging techniques used to evaluate liver structure and function. MRI provides high-resolution images of the liver, helping to detect abnormalities such as tumors, fatty liver disease, or cirrhosis. 

MRCP is useful for visualising bile ducts and detecting blockages or diseases affecting the bile flow, such as primary biliary cholangitis or gallstones. 

Liver DNA or mRNA Analysis
Liver DNA or mRNA analysis is a molecular diagnostic technique used to detect genetic mutations or alterations in gene expression associated with liver diseases. By analysing the genetic material in liver cells, this test can identify liver cancer, genetic liver diseases like viral infections, hemochromatosis or Wilson's disease. 

mRNA analysis, on the other hand, helps in the detection of certain genes that are upregulated or downregulated in response to liver injury or disease. This test offering an understanding of the disease's molecular underpinnings and guiding targeted therapy for disorders such as liver cancer.
