How To Prepare For Liver Function Blood Test?
It is advised to avoid eating fatty or fried foods for at least 24-48 hours before the healthcare provider can collect your blood for the Liver Function Test.
It is also best to avoid drinking alcohol or using drugs at least 48 hours before the test, as it may hamper the test result’s accuracy; instead, drink plenty of water before the test to help with blood circulation and hence make it easier to draw blood for the lab technician.However, if you are currently taking any medications, it is important to let the provider know this before the test. They might request you stop taking certain medications before the test for accurate results.
What Happens During LFT Testing?
A Liver Function Blood Test only takes a few minutes.
- As per the scheduled time of the blood test, a Lab Technician who usually takes blood samples will arrive.
- A thin needle will be used to draw blood from your arm’s vein.
- The needle might cause a mild pinch and some discomfort.
- The lab technician then fills a collection tube with blood and then removes the needle from the skin.
- They place a small bandage on the arm
- These samples are then sent over to the laboratory for analysis of the levels of certain compounds, including Alanine Aminotransferase (ALT), Aspartate Aminotransferase (AST), Alkaline Phosphatase (ALP), and Gamma-Glutamyl Transferase (GGT)
Please note there might be slight pain or bruising at the spot of insertion, but most of the symptoms go away quickly.
