Device (10; 30; 50) for analysing liquid samples comprising amplified nucleic acids, said device comprising: a sample pad; a first and a second sample analysis strip configured to analyse different aspects of the nucleic acid sample, wherein the first and second strips are elongated and extend from the sample pad and each of said first and second strips comprises a substantially straight analysis section divided into a number of segments, each configured to indicate if a target nucleic acid with a predetermined sequence is present in or absent from said sample, which target nucleic acid with a predetermined sequence is directly or indirectly coupled to a detection molecule, and wherein the analysis sections of said first and second sample analysis strips comprises a backing film covered by a transparent layer with a thickness of at least 0.1 mm, said analysis sections are configured to analyse the presence or absence of nucleic acids with different predetermined sequences, said analysis sections of the first and second sample analysis strips having substantially the same length and being arranged side by side such that the analysis result is detectable from the combination of three- dimensional marks appearing in the transparent layer of aligned segments of said first and second analysis strips, 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 enclosing said sample pad and at least two elongated sample analysis strips, said housing comprising a front side in which a sample inlet passage is formed such that the sample pad is accessible from the outside of the housing and at least one opening such that the analysis result is detectable from the outside of the housing. a sample pad; a first and a second sample analysis strip configured to analyse different aspects of the nucleic acid sample, wherein the first and second strips are elongated and extend from the sample pad and each of said first and second strips comprises a substantially straight analysis section divided into a number of segments, each configured to indicate if a target nucleic acid with a predetermined sequence is present in or absent from said sample, which target nucleic acid with a predetermined sequence is directly or indirectly coupled to a detection molecule, and wherein the analysis sections of said first and second sample analysis strips comprises a backing film covered by a transparent layer with a thickness of at least 0.1 mm, said analysis sections are configured to analyse the presence or absence of nucleic acids with different predetermined sequences, said analysis sections of the first and second sample analysis strips having substantially the same length and being arranged side by side such that the analysis result is detectable from the combination of three- dimensional marks appearing in the transparent layer of aligned segments of said first and second analysis strips, 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 enclosing said sample pad and at least two elongated sample analysis strips, said housing comprising a front side in which a sample inlet passage is formed such that the sample pad is accessible from the outside of the housing and at least one opening such that the analysis result is detectable from the outside of the housing.
