The invention relates to a method for confirming an amplified nucleic acid target sequence (target sequence), preferably from human samples, during a multiplication reaction in a collective and continuous reaction batch as a one-pot process, wherein the confirmation of the target sequence amplification product is obtained by means of a hapten-pair-marked artificial template amplification product. The artificial template sequence is amplified and optionally marked by means of the 5′-cleavage products of the at least one target-sequence-specific FEN probe. The 5′-cleavage product of the at least one target-sequence-specific FEN probe is obtained only if the FEN probe hybridizes, by means of the target-sequence-specific 3′ sequence thereof, to a complementary sequence segment of the at least one target sequence. The detection of the obtained plurality of template amplification products occurs distinctly and preferably by means of immunochromatographic methods.
