The present invention relates to an enhanced extracting and sampling device for collecting faeces samples, particularly suitable for performing laboratory diagnostic tests in a total laboratory automation, in particular for dosing one or more analytes, and allowing the screening of markers of diagnostic interest for purposes of prevention and treatment. Such a device for sampling faeces may indeed be received and processed by robotic systems in highly automated analysis laboratories as the samples of body fluids (whole blood, plasma, serum, etc.) are processed.
