Could quantitative liver function tests gain wide acceptance among hepatologists?

It has been emphasized that the assessment of residual liver function is of paramount importance to determine the following： severity of acute or chronic liver diseases independent of etiology; long-term prognosis; step-bystep disease progression; surgical risk; and efficacy of antiviral treatment. The most frequently used tools are the galactose elimination capacity to asses hepatocyte cytosol activity, plasma clearance of indocyanine green to assess excretory function, and antipyrine clearance to estimate microsomal activity. However, a widely accepted liver test （not necessarily a laboratory one） to assess quantitative functional hepatic reserve still needs to be established, although there have been various proposals. Furthermore, who are the operators that should order these tests？ Advances in analytic methods are expected to allow quantitative liver function tests to be used in clinical practice.
