The Liver Function Test (LFT) is a blood test that measures the levels of various enzymes, proteins, and substances in the blood to assess how well the liver is functioning.It is useful in diagnosing liver diseases such as hepatitis, cirrhosis, and fatty liver disease and provides valuable insights into liver damage or inflammation
Indications for Liver Function Test:
● Fatigue or weakness: If you experience unexplained tiredness or weakness, LFT can help determine whether liver dysfunction is contributing to your symptoms.
● Abdominal pain or discomfort: Pain, discomfort or heaviness in the upper right quadrant of the abdomen, can indicate liver problems.
● Yellowing of the skin or eyes (Jaundice): High bilirubin levels in the blood may lead to jaundice, and an LFT can help diagnose the underlying cause.
● Nausea, vomiting, or loss of appetite: These can be symptoms of liver conditions such as hepatitis or cirrhosis.
● Exposure to risk factors: Individuals with a history of alcohol consumption, viral infections, or drug use should undergo LFTs regularly to check for liver damage.
How Liver Function Test Works:
LFT typically includes measuring levels of bilirubin, albumin, alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and prothrombin time. High or low levels of these substances can indicate liver damage or dysfunction.
● Bilirubin: A substance produced when red blood cells are broken down. High levels suggest liver disease.
● Albumin: A protein made by the liver. Low levels may indicate liver damage or cirrhosis.
● ALP: Elevated levels can indicate a blocked bile duct or bone disease.
● AST and ALT: Enzymes that are released when liver cells are damaged. Elevated levels indicate liver inflammation.
● Prothrombin Time: Measures how long it takes for blood to clot. Longer clotting times may indicate liver dysfunction.
Normal Range:
● Total Bilirubin: 0.1–1.2 mg/dL
● Albumin: 3.4–5.4 g/dL
● ALP: 44–147 IU/L
● AST: 10–40 IU/L
● ALT: 7–56 IU/L
● Prothrombin Time: 11–13.5 seconds
Abnormal Test Significance:
● Elevated bilirubin levels: Can indicate liver disease, gallstones, or hemolytic anemia.
● Low albumin levels: Suggest liver damage, cirrhosis, or nephrotic syndrome.
● Elevated ALP levels: Can indicate bile duct obstruction, liver cancer, or bone diseases.
● High AST and ALT: Elevated AST and ALT levels are indicative of liver inflammation or hepatitis.
● Prolonged prothrombin time: Can be a sign of liver cirrhosis or liver failure.
Management Based on Results:
● For liver diseases: Treatment depends on the condition, ranging from medications for hepatitis or fatty liver disease to liver transplant in severe cases of cirrhosis or liver failure.
● For bile duct obstruction: Surgical procedures or endoscopic treatments may be needed to remove blockages.
● For fatty liver disease: Lifestyle changes like weight loss, dietary modifications, and exercise are essential.
Price in India:
Approx. ₹1,500 – ₹5,000 for a Liver Function Test panel.The Ketone Test measures the levels of ketones in the blood or urine. High ketone levels are a sign of diabetic ketoacidosis (DKA), a life-threatening condition that can occur in individuals with type 1 diabetes or type 2 diabetes.
Indications for Ketone Test:
● Uncontrolled diabetes: To check for ketones in individuals with poorly controlled blood glucose levels.
● Symptoms of diabetic ketoacidosis (DKA): Such as nausea, vomiting, fruity-smelling breath, and abdominal pain.
● Sick days: During illness or infection, the body may produce more ketones, so monitoring is essential for diabetes patients.
How Ketone Test Works:
● The test can be performed on a blood sample (blood ketone test) or urine sample (urine ketone test) to measure the level of acetoacetate, acetone, and beta-hydroxybutyrate—the three main ketones produced during fat metabolism.
Normal Range:
● Blood ketone levels: 0.6–1.5 mmol/L.
● Urine ketone levels: Negative or trace.
Abnormal Test Significance:
●Elevated ketone levels: Indicate the body is burning fat instead of carbohydrates for energy, often seen in diabetic ketoacidosis or in individuals following a ketogenic diet.
Management Based on Results:
● For high ketone levels: Immediate intervention is needed to prevent diabetic ketoacidosis, which may involve insulin therapy and fluid replacement.
Price in India:
Approx. ₹500 – ₹1,000 for ketone testing.
FAQs
How often should I get a liver function test?
If you are at risk for liver disease (due to alcohol use, viral infections, or obesity), it’s recommended to get tested annually.
What are the symptoms of liver problems?
Symptoms may include fatigue, yellowing of the skin, abdominal pain, nausea, and loss of appetite.
Disclaimer: Liver function tests are useful in diagnosing liver disease but should be interpreted by a healthcare provider in conjunction with other diagnostic tests and clinical findings.
