Understanding the Liver Function Tests
The liver function test is prominently known as LFT. It is a routine blood test that provides you with a window into the detailed world of liver health. You can just think of them as liver report cards. It indicates how well it's handling the different tasks. But what exactly does the liver function test all about?
The key players in the assessment include enzymes, proteins, and bilirubin enzymes, including Lt. AST, which indicates liver cell damage when it is increased. No matter whether bilirubin is a yellow pigment, it helps in understanding how well your liver is processing the waste.
These tests support the diagnosis of liver illnesses, the assessment of the general health of the liver, and the tracking of therapy efficacy. Typically, these charts include the following tests:
- Aspartate amylase (AST) and alanine aminotransferase (ALT): These enzymes aid in the evaluation of liver injury.
- Alkaline phosphatase (ALP): Increased levels may indicate problems with the liver or bones.
- Bilirubin: Elevated bilirubin levels may be a sign of liver or red blood cell dysfunction.
- Total Protein and Albumin: These assess liver function in relation to protein synthesis.
The normal range for each test is usually shown on the liver function test normal range chart, which helps medical professionals comprehend and interpret the findings of different tests. It assists in detecting departures from the typical range, suggesting possible disorders or problems with the liver.
Medical professionals use this chart as a comparison tool to evaluate the liver health of their patients. Interpretation entails determining whether the patient's results are within the defined reference range, showing normal liver function, or whether they differ, pointing to possible issues that would require additional research or care.
Why should you go for liver function tests regularly?

Normal ranges and interpretations
It is important to know that the normal ranges for liver function tests can vary slightly from one lab to another. Your factors can also influence it.

6.0 – 8.3 g/dL |
Common Liver Diseases and Liver Function Tests
- Viral infections often cause it. It can increase the ALT and AST levels to a great extent. A late stage of scarring of the livers is cirrhosis, and it can lead to decreased albumin and total protein. It might show elevated liver enzymes.

- Even though it is tempting to play detective with your health, it is a risky game to interpret LFT results at home. You should always consult a medical expert for accurate analysis and diagnosis.
