Abstract: The present invention relates to a device (10; 30; 50) for analysing liquid samples comprising amplified nucleic acids, said device comprising: a sample pad (16); a first (18) and a second (19) sample analysis strip configured to analyse different aspects of the nucleic acid sample wherein said segments comprise nucleic acid sequences which are complementary to the predetermined sequences of target nucleic acids whose presence or absence is analysed; and a housing (11) enclosing said sample pad and at least two elongated sample analysis strips wherein the analysis result is detectable from the outside of the housing from the combination of aligned segments of said first and second analysis strips. The invention furthermore relates to a method for determining the presence or absence of a target nucleic acid, providing confirmatory results, in combination with a predetermined sequence in a sample from a subject using the device according to the invention.
