Abstract: The present invention relates to a method and test kit for detecting specific nucleic acid sequences, comprising the steps of: 1. matrix-dependent new synthesis of the target nucleic acid; 2. target-specific probe hybridization; and 3. detection of the hybridization event. The invention is characterized in that, in the first step, an oligonucleotide 1, which is marked by a marker 1 and is entirely or partially complementary to the target sequence, acts as a primer in the matrix-dependent new synthesis of the target nucleic acid and, in the second step, an oligonucleotide 2, which is marked by a marker 2 and, owing to its melting temperature being lower than that of the oligonucleotide 1, is not involved in the first step, partially or completely hybridizes with the DNA new synthesis product of oligonucleotide 1.The detection of the hybridization reaction can take place both fluorometrically in the form of a homogeneous assay and, for verification of the result, subsequently immunologically.
