The invention concerns a method applied to a substance treated to exhibit a biological activity, for example a coagulating or anticoagulation activity. The treated substance has been obtained, from a source substance having the biological activity, after a treatment such that the treated substance does not contain any molecule of the source substance in significant amount. The treatment may consist in carrying out a high dilution process of the type used for producing homeopathic solutions or granules. The method is designed to diagnose potential alterations of the treated substance by external factors. It comprises the step which consists in: placing a reference substance sample in a zone (19) protected from external influence; subjecting a sample of the treated substance to external influence (20); comparing the results of the tests carried out using a biological control system respectively with the reference substance sample and the treated substance sample. Thus, if the results of the tests are different, the alterations of the treated substance by external influence (20) are demonstrated.
