A method for discriminating single nucleotide polymorphisms (SNPs) offers improved sensitivity and specificity. A test kit is also provided. The method may be for genotyping in typing assays applied to a biological sample. The method may include steps of performing a real-time amplification of the target, generating multiple copies of amplicons, in presence of at least two different labeled probes, each probe allowing real-time detection at the SNP position of both the wildtype and at least one possible mutation, assessing the discriminatory variable value(s) based on the signals of each combination of two detection probes, and discriminating between the genotypes. The methods may be for diagnostic, preventive and therapeutic applications.
