What is LFT Test?

An LFT (Liver Function Test) is an umbrella term used at reputed diagnostic centres for the group of blood tests that focuses on the hepatic panel of a patient. A doctor would prescribe an LFT when the medical professional wants to learn about the overall condition of a patient’s liver. An LFT test is not a singular test, as already mentioned.

An LFT test could be –

  • Prothrombin time (PT/INR) test
  • Activated partial thromboplastin time (aPTT) test
  • Albumin test
  • Bilirubin (direct and indirect) test, and more.
  • If the results of an LFT test show an elevated level of either liver transaminases aspartate transaminase or alanine transaminase then one can conclude that the patient is suffering from a liver ailment or has sustained injuries to their liver.

    When Do You Need an LFT Test?

    An LFT blood test would be needed when a patient is showing all the telltale signs of liver disease. For instance, if a patient has yellowish skin and eyes as well as suffers frequent bouts of nausea then their doctor would recommend them to take an LFT test.

    What is Included in an LFT Test?

    A liver function test in from a reputed diagnostic centre would begin by drawing a 2 mL sample of blood from the patient. The sample would then be put inside a centrifuge in a bid to separate the serum from the blood cells. About 2 ml of serum from the blood sample would then be subjected to a barrage of test methods depending on the liver function test the doctor of the patient has requested.

    What is the use of an LFT Test?

    What are the Precautions for an LFT Test?

    One might need to stop taking certain medications before their blood is drawn as a sample for an LFT test. One might also need to fast.
