ISOTRANSFERRINS IN BODY FLUID SAMPLE AS A MEASURE OF ALCOHOL CONSUMPTION

摘要

A method for determining the alcohol consumption of an individual by means of quantifying isotransferrin combinations in the individual's body fluids, these combinations being (A) isotransferrins having a pI higher than 5.6 or (B) isotransferrins having a pI higher than 5.8 or (C) isotransferrins having a pI higher than 6.0. The total concentration of any of said combinations (A), (B), (C) is a measure of the said individual's alcohol consumption during the last few weeks. Ion exchange chromatography with constant ion strength and pH (isocratic conditions) is the preferred method for the separation of said isotransferrins.
