Could quantitative liver function tests gain wide acceptance among hepatologists?

Area of Science:

• Hepatology
• Clinical Biochemistry
• Medical Diagnostics

Background:

• Accurate assessment of residual liver function is vital for managing acute and chronic liver diseases, predicting prognosis, and evaluating treatment efficacy.
• Current methods, including galactose elimination capacity, indocyanine green clearance, and antipyrine clearance, assess specific hepatocyte activities but lack universal acceptance for quantitative hepatic reserve.
• The need for a standardized, quantitative liver function test remains unmet, despite various proposed methods.

Discussion:

• The importance of residual liver function assessment spans disease severity, progression, surgical risk, and therapeutic response.
• Existing functional tests measure hepatocyte cytosol activity, excretory function, and microsomal activity.
• A consensus on a universally accepted quantitative liver function test is still lacking.

Key Insights:

• Residual liver function assessment is critical for determining liver disease severity, prognosis, progression, surgical risk, and treatment effectiveness.
• Commonly used tests include galactose elimination capacity (hepatocyte cytosol activity), indocyanine green clearance (excretory function), and antipyrine clearance (microsomal activity).
• A universally accepted quantitative test for hepatic reserve is still needed, highlighting ongoing research and development in this area.

Outlook:

• Future advances in analytical methods are anticipated to enable the routine clinical use of quantitative liver function tests.
• Further research is needed to establish a widely accepted, quantitative measure of hepatic functional reserve.
• Clarifying the roles and responsibilities of healthcare professionals in ordering these tests is also an important consideration.
