Twist Bioscience Corporation announced it will supply the U.S. Centers for Disease Control and Prevention (CDC) with a customized version of Twist SARS-CoV-2 Synthetic RNA Controls for use in the CDC Influenza SARS-CoV-2 (Flu SC2) Multiplex Assay. The CDC SARS-CoV-2 (Flu SC2) Multiplex Assay tests for influenza A, B and SARS-CoV-2 simultaneously. Positive controls provide quality control measures for the development, verification, and ongoing validation of both next-generation sequencing (NGS) and reverse transcription-polymerase chain reaction (RT-PCR) assays. In addition to using the assay at its primary site, CDC intends to distribute this multiplex assay to additional public health laboratories for testing across the United States.
