The present invention relates to a device and a method for analysing a sample comprising from 0.1 pg to 1 μg of analyte, and more specifically to a lateral flow device and a method for testing the presence of very low amounts of drugs or drug metabolites in a sample. The present invention also relates to a method of dissolving a bodily fluid.

Sample analysing device

A sample capture unit comprising a housing defining an enclosed substrate chamber containing a substantially planar sample-capture substrate extending in a plane for receiving a skin-print thereon. The housing comprises: a first part having an aperture providing access to the substrate chamber for depositing a skin-print on the sample-capture substrate; and a second part movable relative to the first part, from a first position in which the aperture is uncovered so as to allow receipt of a sample on the sample-capture substrate, and into a second position in which the aperture is covered, thereby preventing access to the substrate chamber; the housing further comprises a retaining mechanism configured to retain the second part in the second position; and an element having a perimeter defined by a line of frangibility, which enables irreversible detachment of at least a part of the element so as to create an access port dimensioned to allow removal of the sample-capture substrate.

Sample capture unit

A device for receiving and analysing a sample, wherein the analysing involves use of a solution. The device comprises: a sample receiving portion for receiving a sample to be analysed; and a solution capsule having a sealed configuration in which the solution capsule is sealed and a release configuration in which contents of the solution capsule are released via a flow path that provides fluid communication between the solution capsule and the sample receiving portion. The device further comprises a bistable release mechanism comprising an actuator wherein the bistable release mechanism releases only in the event that a force applied to the actuator reaches a threshold force and wherein actuation of the actuator results in one-way conversion of the solution capsule from the sealed configuration into the release configuration.
