LFT 4 parameters
LFT stands for Liver Function Test. It's a group of blood tests used to assess how well your liver is working. The “4 parameters” usually refer to a basic panel of four key liver-related enzymes or substances.
A typical LFT (4 parameters) package might include:
-
ALT (Alanine Aminotransferase) – High levels may indicate liver damage.
-
AST (Aspartate Aminotransferase) – Also elevated with liver or heart problems.
-
ALP (Alkaline Phosphatase) – Can rise with liver or bone disorders.
-
Total Bilirubin – High levels may cause jaundice and indicate liver/bile issues.
A full Liver Function Test (LFT) panel typically includes 8–10 parameters to give a more complete picture of liver health. Here are the most common ones:
Full LFT Panel Includes:
-
ALT (SGPT) – Indicates liver cell injury
-
AST (SGOT) – Also linked to liver and heart conditions
-
ALP (Alkaline Phosphatase) – High in liver, bile duct, or bone problems
-
Total Bilirubin – Measures overall bilirubin (yellow pigment from red blood cells)
-
Direct (Conjugated) Bilirubin – Linked to bile duct issues
-
Indirect (Unconjugated) Bilirubin – Linked to red blood cell breakdown
-
Total Protein – Measures overall protein in blood (liver makes most of it)
-
Albumin – A major blood protein made by the liver
-
Globulin – Other proteins that include immune-related ones
-
A/G Ratio (Albumin/Globulin Ratio) – Balance of albumin and globulins
These tests can help detect:
-
Hepatitis
-
Fatty liver
-
Cirrhosis
-
Bile duct obstruction
-
Liver tumors or damage.

Inclusions & Exclusions
Inclusions
ALT (SGPT) – Enzyme that rises with liver damage
-
AST (SGOT) – Enzyme found in liver and heart
-
ALP (Alkaline Phosphatase) – Enzyme linked to bile ducts and bones
-
Total Bilirubin – Total amount of bilirubin in blood
-
Direct (Conjugated) Bilirubin – Water-soluble form; rises with bile obstruction
-
Indirect (Unconjugated) Bilirubin – Fat-soluble form; rises with red blood cell breakdown
-
Total Protein – Measures all proteins in blood
-
Albumin – Main protein made by the liver
-
Globulin – Group of proteins including antibodies
-
A/G Ratio (Albumin to Globulin Ratio) – Checks protein balance
-
(Optional in some labs): GGT (Gamma-Glutamyl Transferase) – Sensitive to alcohol and bile duct issues
-
(Optional): LDH (Lactate Dehydrogenase) – May be elevated in liver diseases
Exclusions
- Hepatitis Panel (A, B, C tests) – Tests for liver infections (done separately)
Prothrombin Time (PT/INR) – Measures blood clotting ability (liver makes clotting factors)
Liver Ultrasound or Imaging – Physical scans of liver (not a blood test)
FibroScan / Liver Biopsy – For assessing liver stiffness or damage (more advanced)
Ammonia Levels – Important in liver failure, but not included in routine LFTs
Ceruloplasmin – For Wilson’s disease (copper metabolism issue)
Alpha-fetoprotein (AFP) – Tumor marker, used to detect liver cancer
Iron Studies / Ferritin – To check for hemochromatosis (iron overload in liver)
Autoimmune Liver Disease Markers – Like ANA, ASMA, AMA tests
Glycated Hemoglobin (HbA1c) – Related to diabetes, often tested separately if liver disease affects
About The Treatment
A Health Check-Up is a preventive medical examination designed to assess your overall health status and detect early signs of diseases or risk factors. These check-ups typically include a series of physical examinations, laboratory tests, and diagnostic screenings tailored to age, gender, medical history, and lifestyle.
Routine health check-ups are essential for early detection of conditions such as diabetes, heart disease, hypertension, and cancer. They help doctors monitor critical indicators like blood pressure, cholesterol levels, organ function, and more. Depending on the package or provider, a health check-up can range from basic blood tests to advanced imaging like CT scans or full-body MRIs.
