There are several types of methods to determine DNA polymorphisms (SNPs). GeneLink utilizes the Single Base Chain Extension (SBCE) assay which is the most accurate method availalbe to detect single nucleotide polymorphisms. The SBCE assay identifies the (SNP) directly on the DNA.
The profile accuracy is nearly 100%. The assay is performed robotically, which virtually eliminates human error in sample manipulation. In rare instances, when a particular SNP area of a profile 'does not read', it is repeated. All repeats thus far have been successful.
