Tests Included in Liver Function Test:

Liver Function Test (LFT) is a series of blood tests that assess the health and function of the liver. It includes several parameters that provide information about the liver’s ability to process and metabolize substances.

Below is a list of common tests included in an LFT:

  • Alanine Aminotransferase (ALT): Measures the level of ALT, an enzyme found mainly in the liver. Elevated ALT levels can indicate liver damage or disease.
  • Aspartate Aminotransferase (AST): Measures the level of AST, an enzyme present in various tissues, including the liver. Elevated AST levels can indicate liver damage or other health issues.
  • Alkaline Phosphatase (ALP): Measures the level of ALP, an enzyme found in the liver and other tissues. Elevated ALP levels may indicate liver or bone disorders.
  • Total Bilirubin: Measures the level of bilirubin, a waste product produced by the liver. Elevated bilirubin levels can indicate liver problems or other conditions.
  • Albumin: Measures the level of albumin, a protein produced by the liver. Low albumin levels can indicate liver disease.
  • Total Protein: Measures the total amount of protein in the blood, including albumin and other proteins. Abnormal protein levels may indicate liver issues.
  • Gamma-Glutamyl Transferase (GGT): Measures the level of GGT, an enzyme found in the liver and other tissues. Elevated GGT levels can indicate liver or bile duct problems.

sample requiredSample Required for LFT :

The Liver Function Test typically requires a blood sample. A healthcare professional will collect the sample by performing a simple blood draw from a vein in your arm.

test timeLiver Function Test Time:

The test for Liver Function usually takes a few minutes for the blood draw. However, the total time for the test, including sample processing and analysis in the laboratory, may vary. Typically, results are available within a few days.

test normal rangeLiver Function Test Normal Range:

The normal range for liver function test values may vary depending on the specific parameters being measured and individual laboratory reference values. Common parameters include alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), total bilirubin, and albumin. It’s important to consult with your healthcare provider for the interpretation of your specific test results.

Below is the reference table Liver Function Test normal values:

Parameter Normal Range
ALT 7 – 56 U/L
AST 8 – 48 U/L
ALP 44- 147 U/L
Total Bilirubin 0.1 – 1.2 mg/dL
Albumin 3.4 – 5.4 g/dL
Total Protein 6.3 – 7.9 g/dL
GGT 0 – 30 U/L

what is the testWhat is LFT?

The Liver Function Test is a group of tests that evaluate the overall health and function of the liver. It measures various parameters to assess liver function, including liver enzyme levels, bilirubin levels, and albumin levels. The test helps in detecting liver disorders and monitoring the effectiveness of treatment.

test procedureLiver Function Test Procedure:

During the Liver Function Test, a healthcare professional will collect a blood sample from your arm using a needle. The blood sample is then sent to the laboratory for analysis. The test measures the levels of specific substances in the blood to evaluate liver function.

when to take the testWhen to take the LFT:

The timing for the Liver Function Test may vary depending on your specific situation and the guidance of your healthcare provider. It may be performed as part of routine health check-ups, when monitoring a known liver condition, or if you have symptoms of liver dysfunction, such as jaundice, abdominal pain, or unexplained fatigue.

who should take this testWho should take Liver Function test:

The Liver Function Test is recommended for individuals who have risk factors for liver disease, such as excessive alcohol consumption, obesity, viral hepatitis, or a family history of liver disease. It is also performed for those with symptoms of liver dysfunction or as part of routine health screenings.

precautions for exceptional casesPrecautions for exceptional cases (pregnancy, etc.):

For pregnant women or individuals with specific medical conditions, additional considerations and specific liver function tests may be recommended. It is important to inform your healthcare provider about any specific medical conditions, pregnancy, or medications you are taking before undergoing the test.


Frequently Asked Questions for Liver Function Test:

Q1: Is fasting required for the Liver Function Test?

A: Fasting is usually not required for the Liver Function Test. However, there may be specific instructions provided by your healthcare provider, so it’s important to follow their guidance.

Q2: How often should I have a Liver Function Test?

A: The frequency of Liver Function Testing depends on your specific condition, risk factors, and the recommendations of your healthcare provider. It may be performed periodically as part of routine health check-ups or as directed based on your individual needs.

Q3: Can the Liver Function Test diagnose liver disease?

A: The Liver Function Test is an important tool in assessing liver function and detecting signs of liver disease. However, a comprehensive evaluation, including additional tests and clinical assessment, is necessary for a definitive diagnosis.

Q4: Can medications affect the Liver Function Test results?

A: Yes, certain medications and herbal supplements can impact the results of the Liver Function Test. It’s important to inform your healthcare provider about any medications or supplements you are taking before undergoing the test.

Q5: How can I maintain good liver health?

A: To maintain good liver health, it’s important to limit alcohol consumption, maintain a healthy weight, avoid exposure to toxins, practice safe sex to prevent viral hepatitis, and follow a balanced diet. Regular check-ups and monitoring of liver function are also recommended, especially if you have risk factors for liver disease.

Q6: What are the warning signs of a damaged liver?

A: Warning signs include jaundice (yellowing of the skin or eyes), abdominal pain, dark urine, pale stool, fatigue, and unexplained weight loss.

Q7: What do high AST and ALT levels indicate?

A: Elevated levels of AST and ALT can indicate liver inflammation or damage, possibly due to conditions like hepatitis, alcohol abuse, or fatty liver disease.

Q8: What happens if SGOT and SGPT levels are high?

A: SGOT and SGPT are synonyms for AST and ALT, respectively. High levels suggest liver damage, but further evaluation is needed to determine the cause.

Q9: What foods are good for liver repair?

A: Foods like leafy greens, fruits, whole grains, lean proteins, and foods rich in antioxidants (e.g., berries) are beneficial for liver health.

Q10: What happens if LFT results are high?

A: High LFT levels may indicate liver dysfunction or disease. Further tests and consultation with a healthcare provider are necessary for proper diagnosis.

Q11: Can I test my liver function at home?

A: While home tests for liver function are available, consulting a healthcare professional for accurate diagnosis and interpretation is recommended.
