LFT Test For Monitor Liver Function and Disease

Liver Function Tests (LFT) are a group of blood tests that provide important information about the liver, including its ability to process chemicals and filter toxins from the body.

LFT Test Full Form

Full form of LFT Test is Liver Function Tests.

 

LFT Test Means

• LFT stands for Liver Function Test, which is a blood test that measures the levels of various substances produced by the liver.
• The test is used to check the overall health of the liver, diagnose liver diseases, and monitor the effectiveness of treatments.
• LFT measures several substances in the blood, including bilirubin, albumin, alkaline phosphatase (ALP), aspartate transaminase (AST) also known as Serum glutamic-oxaloacetic transaminase (SGOT), and alanine transaminase (ALT) also known as serum glutamic-pyruvic transaminase (SGPT).
• Bilirubin is a waste product produced when red blood cells break down and is processed by the liver. High levels of bilirubin can indicate liver damage or disease.
• ALT and AST are enzymes produced by liver cells. High levels of these enzymes in the blood can indicate liver damage or disease.

Interesting Facts About Liver

• The liver is the largest internal organ in the human body.
• It performs over 500 vital functions, including detoxification, metabolism, and nutrient storage.
• The liver can regenerate itself, allowing it to recover from certain types of damage.
• It produces bile, a substance necessary for the digestion and absorption of fats.
• The liver plays a crucial role in blood clotting by producing important proteins.

 

LFT Test Purpose

• The primary purpose of the LFT test is to help diagnose liver disease, monitor the progression of a known liver condition, or evaluate the effectiveness of treatment for a liver disorder.
• LFT tests are also used to assess the risk of liver damage from medications or other substances, monitor liver function in people with certain medical conditions, and evaluate overall health status.
• LFT tests can help identify liver-related symptoms such as jaundice, fatigue, abdominal pain, and loss of appetite, among others.
• The LFT test is typically ordered by a doctor if liver disease is suspected, or as part of routine medical testing in people with a family history of liver disease or other risk factors.

 

 

LFT Test Preparation

Here are some bullet points regarding LFT test preparation:

 

Before the test:

• Inform the doctor about any medications or supplements you are taking.
• Fasting for at least 8 hours prior to the test.
• Wear loose and comfortable clothing.

 

During the test:

• The test is a simple blood draw that usually takes a few minutes to complete.

 

After the test:

• Resume normal activities and diet, unless advised otherwise by your doctor.
• Follow up with your doctor to discuss the results.

Summary

To prepare for an LFT test, inform the doctor about medications, have a blood sample taken, and follow up with the doctor for result discussion.

 

LFT Test Procedure

Here is the LFT Test Procedure:

• The LFT test is a simple blood test that requires a blood sample to be drawn from a vein in your arm.
• Before the test, the healthcare provider will clean the site where the blood will be drawn with an antiseptic solution.
• A tourniquet will be placed around your upper arm to help locate a vein and make it easier to draw blood.
• The healthcare provider will then insert a needle into the vein and collect a sample of your blood into a test tube.
• After the blood is collected, the needle is removed, and pressure is applied to the site to stop any bleeding.

 

LFT Test Result

• LFT test results show the levels of various liver enzymes, proteins, and bilirubin in the blood. These levels can indicate how well the liver is functioning.
• Abnormal LFT results may indicate liver damage, liver disease, or other health conditions.
• Further testing may be necessary to determine the cause of abnormal LFT results and to develop an appropriate treatment plan.

LFT Test Normal Range

Here is a table showing the normal range values for the most common liver function tests (LFTs):

LFT Test	Normal Range
Total bilirubin	0.1 to 1.2 mg/dL
Direct bilirubin	0.0 to 0.3 mg/dL
Indirect bilirubin	0.2 to 0.8 mg/dL
ALT (SGPT)	8 to 40 units/L
AST (SGOT)	8 to 40 units/L
ALP (alkaline phosphatase)	44 to 147 units/L
GGT (gamma-glutamyl transferase)	0 to 51 units/L
Total protein	6.0 to 8.3 g/dL
Albumin	3.5 to 5.0 g/dL

 

LFT Test Interpretation

Here is a possible LFT Test Interpretation:

LFT Test Component	Normal Range	Interpretation
Total Bilirubin	0.1-1.2 mg/dL	Elevated levels may indicate liver disease, blockage of bile ducts, or other conditions affecting bilirubin metabolism. Low levels indicate Anemia, hypothyroidism, liver disease
Direct Bilirubin	0.0-0.3 mg/dL	Elevated levels may indicate liver disease, blockage of bile ducts, or other conditions affecting bilirubin metabolism. Low levels indicate Bile duct obstruction, liver disease
Indirect Bilirubin	0.2-0.8 mg/dL	Elevated levels may indicate hemolysis, a condition where red blood cells are destroyed more rapidly than normal
AST (SGOT)	8-40 units/L	Elevated levels may indicate liver damage or injury
ALT (SGPT)	8-40 units/L	Elevated levels may indicate liver damage or injury
ALP	44-147 units/L	Elevated levels may indicate liver disease, bone disorders, or other conditions affecting the liver or bones
Total Protein	6.0-8.3 g/dL	Low levels may indicate liver disease, kidney disease, malnutrition, or other conditions affecting protein metabolism
Albumin	3.4-5.4 g/dL	Low levels may indicate liver disease, kidney disease, malnutrition, or other conditions affecting protein metabolism
Globulin	2.0-3.5 g/dL	Elevated levels may indicate chronic infections, autoimmune disorders, or other conditions affecting protein metabolism
