What is LFT test?
This test measures the levels of bilirubin in the blood. Bilirubin is made by the liver and is excreted in the bile. Elevated levels of bilirubin may indicate an obstruction of bile flow or a problem in the processing of bile by the liver.
Liver function test; Tests for Bilirubin, ALT, AST, Total Protein, Alkaline Phosphatase, Albumin, Globulin, Gamma-GT.
Why get a LFT blood test?
The purpose of liver function tests is to: Screen for liver infections, such as hepatitis. Monitor the progression of a condition, such as viral or alcoholic hepatitis, and determine whether treatment is working. Measure the severity of a condition, particularly scarring of the liver (cirrhosis).
You may need liver function testing if you have symptoms of liver disease. The symptoms include Nausea and vomiting, Jaundice, a condition that causes your eyes and skin to turn yellow.
What does the test measure?
To determine if levels of liver chemicals (enzymes), proteins, and other substances are abnormal, a liver blood test looks at the chemicals(enzymes), proteins, and other substances made by the liver. These include:
ALT and AST are liver enzymes that are released into the bloodstream when the liver cells are damaged and indicate how much inflammation is present in the liver. ALT and AST levels are typically high in conditions like hepatitis.
The level of these enzymes can be monitored to enable doctors to determine whether there is liver scarring (fibrosis) due to conditions such as nonalcohol fatty liver disease (NAFLD) and alcohol-related liver disease.
How long do blood test results take?
The target turnaround time for Liver function test results is one working day.
