The invention discloses a test device comprising a substrate suitably adapted so as to provide aperture(s) wherein said aperture(s) are suitably adapted so as to support selected supportive material (3) so that fluid samples can be efficiently dispensed onto said supportive material (3) located within said apertures. Furthermore, said supportive material is further adapted so as to provide suitable guide means for checking the adequacy of the sample collected. Subsequently said test device can be placed in a suitable pouch (12) or the like, wherein said pouch (12) is adapted so as to provide desiccant properties (13) and thus to dry a fluid sample more efficiently. Eventually said test device is presented to an automated analyser for processing or the like, alternatively, said test device may be adapted so as to provide on the spot results. The device can be used for a variety of genetic, infectious or metabolic diseases and/or conditions and provides a user-friendly, cost effective, efficient means of mass screening.
