Abnormal liver function tests (LFTs) are common in primary care, found in 20% of patients. However, these LFT abnormalities often do not indicate significant liver disease, with new diagnoses made in only a fraction of cases.

Area of Science:

  • Internal Medicine
  • Hepatology
  • Clinical Chemistry

Context:

  • Primary care settings frequently order laboratory tests, including liver function tests (LFTs).
  • Abnormal LFTs can manifest as elevated liver enzymes, hyperbilirubinemia, hypoalbuminemia, or abnormal coagulation.
  • Understanding the prevalence and significance of LFT abnormalities in primary care is crucial for effective patient management.

Purpose:

  • To describe the spectrum of liver function test abnormalities encountered in a primary care setting.
  • To determine the diagnostic yield and clinical significance of abnormal LFTs identified during primary care encounters.
  • To analyze the types of liver conditions diagnosed following abnormal LFT findings in primary care.

Summary:

  • A retrospective review of laboratory tests from an urban primary care clinic over 10 months identified abnormal LFTs in 20% of patients (156/1088).

  • New diagnoses were established in 104 patients, with common conditions including non-alcoholic fatty liver disease, Gilbert's disease, infectious hepatitis, alcoholic liver disease, and drug-induced liver injury.
  • While 60 patients had abnormalities deemed negligible, abnormal LFTs ordered for specific complaints were more likely to indicate significant disease (p < 0.001).

    • Impact:

    • Abnormal liver function tests are a frequent finding in primary care but rarely signify serious liver disease.
    • This study highlights the importance of clinical context in interpreting abnormal LFTs, differentiating benign findings from those requiring further investigation.
    • Findings can guide primary care physicians in managing patients with abnormal LFTs, potentially reducing unnecessary referrals and investigations.
