The AccukitTM ONCO1LB kit was designed for researchers who perform clinically relevant NGS-based tests, as well as the pharma and CRO labs sponsoring these tests. The kit contains a blend of 13 synthetic DNA standards to clinically important oncogenic regions of the genome. Spiked into the sample as a single reagent addition prior to library prep, the Accukit ONCO1LB controls provide a “background” reference call for each of the matching regions of the genome, providing accurate LOB and performance information, reducing false positive and false negative calls for more accurate clinical interpretation.
