The Carrier Test Plus for autosomal-recessive disorders is a laboratory test that uses next generation sequencing (NGS) technology for the detection of +6000 mutations described in the databases as the cause of +300 recessive diseases. The Carrier Test Plus analyzes complete coding regions and therefore, avoids performing, in most of the cases, a different genetic test for compatibility determination between individuals. The NGS allows us to approach, in a single analysis, the study of different types of mutations: single nucleotide (SNVs), small insertions / deletions, and variants.
