Abstract
Abstract A method for assessing or determining alcohol consumption rates including using a blood specimen from a human subject to develop an individual blood constituent panel; comparing the individual panel with a reference blood constituent panel to provide categories corresponding to rates of alcohol consumption; and identifying the category of consumption rate. The methods of the invention can be varied through modification of one of several statistical models used therewith to preferentially weigh the analysis and identify one consumption category over another. Multi-variate and similar such statistical techniques correlate comparisons of individual/subject blood and reference panel constituents with recognized consumptions rates.

Claims Analysis
Total Claims: 33
Claim 1
Independent Claim
96 words
A method of initially assessing alcohol consumption rates, comprising: using a blood specimen from a human subject to develop an individual blood constituent panel, said panel having at least ten constituents including a ratio of direct bilirubin concentration to total bilirubin concentration as a constituent; comparing said individual panel with a reference blood constituent panel to provide categories corresponding to rates of alcohol consumption, said blood reference panel including the ratio of direct bilirubin concentration to total bilirubin concentration as a constituent; and identifying the category of consumption rate for said subject indicated by said comparison.
