Liver Function Test (LFT) is a blood test that measures the levels of several substances (enzymes and proteins) excreted by your liver.
Levels that are higher or lower than normal can indicate liver problems and this package helps in the diagnosis of liver diseases or conditions.
The test is advised if a person has symptoms like nausea, vomiting, yellow skin and eyes (jaundice), abdominal pain and swelling, dark urine colour, pale stool colour, chronic fatigue, history of hepatitis, family history of liver disease, over weight, alcohol abuse and consumption of medication that may cause liver damage.
This test is used as a routine health check-up, monitoring of hepatitis, alcoholism, monitoring of liver disease or condition and response to medication/treatment.
Frequently asked questions
How is the blood sample taken?
To take the blood sample, a tourniquet (elastic) band is placed tightly on the upper arm. The patient is then asked to make a fist. This helps in the build-up of blood filling the veins and it becomes easy to collect the blood. The skin is cleaned before inserting the needle in the vein in order to prevent bacteria from entering. Needle is inserted into the vein of the arm and the blood sample is collected in the vacutainer.
