The Dietetic Test (cytotoxic test) is a methodology patented at the European level for both its reading techniques as well as for the preparation modality of the suspension to be read. The (lyophilized) reagents used are produced by an important international pharmaceutical industrial concern in conformance with the ISO 9001 norms and are individually certified.

In preparing the slides, substances that could interfere with the leucocytic response are not used, (e.g., chemical products used to obtain maximum adhesion of the lyophilized elements on the slide, or other chemical derivatives added for various reading purposes
