ABSTRACT:
A method to determine presence of a disease condition in a medical patient by evaluating conductivity information. Point-attributes values obtained from highly accurate conductivity data-sets taken as a function of time, over a period of time, are compared to previously determined threshold values. Z-scores may be determined to combine a plurality of point-attribute values in formulation of a composite score for a patient. Sometimes, z-scores are weighted by overall accuracy of the point-attribute in predicting presence of the disease.
