This invention is concerned with a method for evaluating the dynamic biological state of a patient, said method, which involves measuring several elements or substances contained in the blood and interpreting results of the measurements carried out, comprising the following steps (1.degree.) taking a sample of blood from the patient to be examined; (2.degree.) determining hematic substances serving as metabolic and/or tissue parameters; (3.degree.) measuring, on the basis of the determination of step (2.degree.), the totality or part of indexes J1 to J157 defined in the disclosure; and (4.degree.) comparing at least part of said indexes J1 to J157 with similar values obtained at steps (2.degree.) and (3.degree.) on subjects already identified as healthy, to dynamically assess the biological state of the patient to be examined. This invention is also concerned with a software product for executing on a computer steps (3.degree.) and (4.degree.).
