Approach to Abnormal Liver Biochemistries in the Primary Care Setting

Area of Science:

• Hepatology
• Primary Care Medicine
• Clinical Biochemistry

Background:

• Liver biochemistry tests are frequently ordered in primary care.
• Abnormal results can occur even in asymptomatic individuals, necessitating careful interpretation.
• Physicians require a structured method for managing abnormal liver function tests.

Purpose of the Study:

• To provide primary care physicians with a systematic approach to interpreting abnormal liver biochemistry tests.
• To outline common causes, diagnostic workup, and referral criteria for abnormal liver function.
• To aid in appropriate patient management and timely intervention.

Main Methods:

• Review of patterns of liver biochemistry derangement.
• Identification of common aetiologies and relevant history/examination findings.
• Guidance on initial investigations and urgent referral criteria.

Main Results:

• Presents a systematic framework for interpreting abnormal liver biochemistries.
• Details common causes and necessary diagnostic steps.
• Defines critical indicators for emergency department referral.

Conclusions:

• A systematic approach is crucial for managing abnormal liver biochemistry in primary care.
• Understanding test patterns and aetiologies aids in appropriate investigation and referral.
• This review empowers primary care physicians to effectively manage liver biochemistry abnormalities.
