Your liver is one of the most important organs in the body. It helps process nutrients, remove toxins, support digestion, store energy, and produce proteins required for many body functions. A Liver Function Test, commonly called an LFT, is a blood test that helps assess how well the liver is working. Doctors often recommend this test during routine health checkups, when symptoms suggest a liver problem, or when monitoring certain medications. Regular liver health monitoring can help identify problems early and support timely medical care.
A Liver Function Test is a group of blood tests that measure enzymes, proteins, and substances produced or processed by the liver. The test helps healthcare professionals evaluate liver health and identify signs of liver injury, inflammation, or impaired liver function. A small blood sample is collected from a vein and sent to a laboratory for analysis. Results are usually available within a short period depending on the laboratory and healthcare facility.
LFT results can provide useful information about many liver-related conditions. The test may help detect liver inflammation, viral hepatitis, fatty liver disease, alcohol related liver damage, cirrhosis, bile duct disorders, and medication-related liver injury. Abnormal values do not always indicate serious disease, but they may suggest that further medical assessment is needed.
Alanine Aminotransferase (ALT or SGPT): Measures liver cell injury and is one of the most sensitive markers for detecting liver inflammation, fatty liver disease, hepatitis, and other liver conditions.
Aspartate Aminotransferase (AST or SGOT): An enzyme found in the liver and other tissues that may increase when liver cells are damaged or inflamed due to disease or injury.
Alkaline Phosphatase (ALP): Helps evaluate bile duct health and may rise when there is blockage, inflammation, or disease affecting the liver or biliary system.
Bilirubin: Measures the liver’s ability to process and remove waste products from red blood cells, helping identify jaundice and liver function abnormalities.
Albumin: Assesses the liver’s ability to produce essential proteins that help maintain fluid balance and support various functions throughout the body.
SGOT, also known as AST, and SGPT, also known as ALT, are enzymes commonly measured in a liver function test. ALT is found mainly in the liver and is often considered a more liver specific marker. AST is present in the liver, heart, muscles, and other tissues. Elevated levels may indicate liver inflammation, fatty liver disease, hepatitis, alcohol related liver injury, or other conditions affecting liver cells. Healthcare professionals often review both values together rather than relying on a single result.
Reference ranges can vary slightly between laboratories, age groups, and testing methods. The values below represent commonly used adult reference ranges and should be interpreted by a qualified healthcare professional.
|
Test |
Typical Normal Range |
|
ALT (SGPT) |
7–56 U/L |
|
AST (SGOT) |
10–40 U/L |
|
ALP |
44–147 U/L |
|
Total Bilirubin |
0.1–1.2 mg/dL |
|
Albumin |
3.5–5.0 g/dL |
Normal results generally suggest that the liver is functioning within expected limits. Mildly elevated results may occur due to temporary illness, medications, obesity, or fatty liver disease. Significantly high values may require further investigation to identify the underlying cause. Results should always be reviewed alongside symptoms, medical history, physical examination findings, and other investigations. Medical decisions should not be based solely on a single test value.

High liver enzyme levels can occur for many reasons. Common causes include fatty liver disease, viral hepatitis, alcohol consumption, obesity, metabolic conditions, certain medications, bile duct disorders, and autoimmune liver diseases. Temporary increases may sometimes occur after illness or intense physical activity. A high result does not automatically mean severe liver damage, but it should be evaluated by a healthcare professional to determine the cause and appropriate next steps.
Possible signs of liver damage include jaundice, fatigue, dark urine, pale stools, swelling in the abdomen, nausea and vomiting, and unexplained weight loss. Some people may experience itching, loss of appetite, or swelling in the legs. Liver disease may not cause noticeable symptoms during its early stages, which is one reason routine screening may be recommended for individuals with risk factors.
People can monitor symptoms such as jaundice, persistent fatigue, abdominal swelling, or unexplained digestive issues. Some healthcare providers offer home blood sample collection services, allowing liver function tests to be performed without visiting a clinic. However, symptoms alone cannot accurately assess liver health, and home monitoring should not replace professional medical evaluation. Laboratory testing remains the most reliable way to assess liver function.
No. A Complete Blood Count, or CBC, evaluates blood cells including red blood cells, white blood cells, and platelets. A Liver Function Test measures liver related enzymes, proteins, and bilirubin levels. These tests serve different purposes. In many situations, healthcare professionals may recommend both CBC and LFT testing together as part of a comprehensive health assessment.
There is no single test that provides all information about liver health. A standard Liver Function Test panel is usually the first step because it evaluates multiple markers at the same time. Depending on symptoms and results, additional tests such as hepatitis screening, ultrasound imaging, FibroScan assessments, CT scans, MRI studies, or other specialized investigations may be recommended.
A Kidney Function Test evaluates how well the kidneys filter waste products and maintain fluid balance. Common markers include creatinine, urea, and estimated glomerular filtration rate. A Liver Function Test evaluates liver enzymes, proteins, and bilirubin levels. While both tests assess different organs, they are often requested together during preventive health screening and chronic disease management.
Before comparing kidney and liver function tests, it is helpful to understand how kidney assessments work. Our guide on Kidney Function Tests Explained: Types, Normal Ranges, and Results provides a detailed overview of the tests and their significance.
Testing kidney and liver function together can provide a broader view of overall health. Combined screening may be useful for people with diabetes, hypertension, obesity, chronic medication use, or long term medical conditions. Monitoring both organs can help healthcare professionals detect changes early and make informed decisions about treatment and follow up care.
The cost of a Liver Function Test in Dubai can vary based on the healthcare provider, laboratory, location, and package selected. Standalone LFT testing commonly ranges from AED 80 to AED 300. Comprehensive health screening packages that include liver testing may cost more. Some providers also offer home sample collection services, which may involve an additional fee depending on the location and service type.
Liver function testing may be recommended for people with diabetes, obesity, fatty liver disease risk factors, regular alcohol consumption, a family history of liver disease, or long term medication use. Individuals with symptoms such as jaundice, persistent fatigue, unexplained abdominal discomfort, dark urine, or abnormal imaging findings may also require testing. The frequency of testing depends on individual health needs and medical advice.
