Abstract
Abstract A method for establishing a treatment protocol for correcting an abnormal condition of disease in a living organism is described. The method comprises the steps of analyzing body fluids from normal and abnormal individuals to generate analysis patterns of the normal and abnormal fluids, comparing the patterns to determine differences in the patterns, and establishing a treatment protocol for the abnormal individual through chemical or metabolic therapy which treating will normalize the abnormal pattern.

In a method of identifying abnormalities in a body fluid of an individual which comprises the steps of determining the presence and relative concentration of electrochemically active compounds contained in said body fluid by passing a sample containing said body fluid sequentially through a liquid chromatographic column for achieving time-space separation of materials eluting from the column and an eletrochemical detection apparatus for electrochemically testing a sample containing electrochemically active materials in solution, the detection apparatus comprising a plurality of coulometric cells arranged in series, the improvement which comprises maintaining a number of the testing electrodes of said coulometric cells at different potentials, said cells operating at progressively varying potentials along the path of flow of the eluant through the cells, each said testing electrode having a sufficiently large surface to volume ratio to provide a sufficient number of half times, at the rate of flow of the eluant through each cell, to provide essentially 100% of possible charge transfer at the potential on said testing electrode, maintaining the total volume of the columetric cells sufficiently small that the transit time through the cells of a single material in the eluant is insignificant with respect to overall elution times, recording the results of coulometric measurements from said cells so as to separate said measurements by measuring potential as well as by time of elution, and comparing the said relative concentrations thus obtained with known concentrations of normal or abnormal body fluids.
