Interpreting abnormal liver function tests (LFTs) can be challenging, as not all abnormalities indicate liver disease. This review guides clinicians through LFT interpretation, considering biochemistry and pathophysiology.

Area of Science:

  • Clinical Biochemistry
  • Hepatology
  • Diagnostic Medicine

Background:

  • Abnormalities in liver function tests (LFTs) are frequently encountered in clinical practice.
  • The rise of automated laboratory testing has increased the detection of incidental LFT abnormalities.
  • Distinguishing true liver disease from non-pathological LFT variations is a diagnostic challenge.

Purpose of the Study:

  • To provide a comprehensive review of liver function tests.
  • To elucidate the pathophysiology behind various biochemical liver tests.
  • To outline a systematic approach for interpreting abnormal liver function test results.

Main Methods:

  • Review of existing literature on liver function tests and their interpretation.
  • Discussion of the biochemical basis and clinical significance of common LFTs.

Related Experiment Videos

  • Presentation of a structured diagnostic algorithm for abnormal LFTs.

    • Main Results:

    • LFT abnormalities do not always correlate with the presence of liver disease.
    • Understanding the specific biochemical markers and their underlying pathophysiology is crucial.
    • A systematic approach aids in accurate diagnosis and patient management.

    Conclusions:

    • Clinicians require a clear framework for interpreting abnormal LFTs.
    • Differentiating true liver pathology from benign variations is essential for appropriate patient care.
    • This review offers a practical guide for navigating LFT interpretation.
