Purpose of Liver Function Test (LFT)
The liver function test is a panel of tests that tell you about the functioning of your liver. This is a blood-based test where a technician or a phlebotomist will take your blood sample to do the testing.
Liver function test diagnoses the liver diseases by measuring the levels of proteins, liver enzymes and bilirubin in your blood.
The liver function test consists of testing multiple parameters that help in the evaluation, detection, and monitoring of liver diseases or damages. It includes the following parameters
- Aspartate aminotransferase (AST) – measures enzymes that release in response to disease
- Alanine aminotransferase (ALT) – measures enzymes that release in response to liver dysfunction
- Alkaline phosphatase (ALP)
- Bilirubin – include Total Bilirubin, Direct Bilirubin, Indirect Bilirubin. Bilirubin tests measure how well the liver disposes of bilirubin, a waste product of blood.
- Total protein (TP)
- Gamma-glutamyl transferase (GGT)
- Prothrombin time (PT)
The liver is considered the workhorse of our body performing various important functions including conversion of fats, carbohydrates, and proteins, is a storehouse of some vitamins and, metabolism of certain hormones. Its functioning impacts most body functions in one way or the other. Some of the other functions of the liver include:
- Converts carbohydrates and some amino acids into glucose which gives energy to the body
- Works on the proteins to make them usable for the body
- Helps in the breakup of waste materials that is then passed out of the body through urine
- Processes alcohols and various medicines including antibiotics
- Processes certain hormones including the thyroid hormones and estrogen
- Contributes to the production of Vitamin D in the body along with skin and kidneys
- Helps in the formation of cellular components of blood
Many of us abuse the liver through our own voluntary actions like excessive alcohol drinking or eating unhealthy food. Unfortunately, there are also things that are beyond our control that are harming our lives irreparably.
The chemical-laced food that has become commonplace in our country, where regulation implementation is really lax, harms our liver. Additionally, some medicines impact liver function, as a side effect. The author knows of a relative, who was on Parkinson’s medication.
The doctor failed to mention that the medicines for Parkinson’s disease can cause liver damage. The relative died of liver cirrhosis when a simple liver function test could have identified the problem earlier and remedial steps could have been taken.
In the Indian context, it is recommended that all individuals above the age of 30 should get a liver function test done as a part of annual preventive health check-up. People who have the following symptoms or attributes should consider getting a liver function test done at regular intervals.
- Weakness, fatigue or loss of energy
- Yellow skin or eyes
- Abdominal pain
- Weight loss
- Family history of liver disease
- Too much eating of fast food
- People of regular medication for diseases like Parkinson’s
As it is a simple blood test, there is no special preparation required before the test. Your doctor may advise you not to take some food or medications that may affect the protein or enzyme levels in your blood. Some doctors may ask to fast for some period of time prior to the test.
Liver dysfunction can be tested through a basic blood test called the liver function test. This test can be a part of preventive health check-up or is prescribed by doctors as the first screening test.
During the test, a healthcare professional will clean your skin with an antiseptic so that the microorganisms present in your skin will not affect. Then, he will wrap an elastic band around your arm to easily access the veins swollen with blood.
He will draw blood samples using a needle and cleans the injected area with cotton to stop bleeding. The blood samples taken will be sent to the lab for analysis.
It usually takes a few minutes to complete this test. Home collection can be arranged if you don’t have time to visit the lab.
Normal Range of Liver Function Test Parameters
Normal blood test results for typical liver function tests include:
- ALT. 7 to 55 units per liter (U/L)
- AST. 8 to 48 U/L
- ALP. 45 to 115 U/L
- Albumin. 3.5 to 5.0 grams per deciliter (g/dL)
- Total protein. 6.3 to 7.9 g/dL
- Bilirubin. 0.1 to 1.2 milligrams per deciliter (mg/dL)
- GGT. 9 to 48 U/L
- PT. 9.5 to 13.8 seconds
These results are for a typical male. Normal results vary from lab to lab and might be slightly different for women or children. LFT test results are generally available within a day.
