Summary
Elevated transaminases indicate liver damage. Initial tests focus on drug toxicity and Hepatitis A, with other viruses being common causes. Rare diseases and liver biopsy are typically considered only in severe or persistent cases.
Area of Science:
- Hepatology
- Clinical Biochemistry
- Virology
Context:
- Elevated serum transaminases are abnormal findings requiring investigation.
- Differential diagnosis of abnormal liver function tests is crucial.
- Identifying the etiology of liver enzyme elevation guides patient management.
Purpose:
- To outline an efficient diagnostic approach for elevated serum transaminases.
- To prioritize common causes of liver injury over rare conditions.
- To define criteria for further, more invasive investigations.
Summary:
- Drug-induced liver injury and toxins should be ruled out first.
- Hepatitis A IgM testing is an initial diagnostic step.
- Common viral hepatitis with benign courses are frequent causes.
- Further investigation for rare diseases or liver biopsy is reserved for severe or prolonged cases.
Impact:
- Provides a practical diagnostic algorithm for clinicians.
- Reduces unnecessary investigations and costs.
- Facilitates timely diagnosis and management of liver disease.
