MDx-Chex™ for BCID2

MDx-Chex for BCID2 is a first-of-its-kind quality control designed to meet the standards for verifying the performance of sample-to-result molecular tests for sepsis. Provided in a comprehensive and easy-to-use format, MDx-Chex for BCID2 evaluates the entire analytical process of the test, including cell lysis, DNA extraction, purification and removal of PCR inhibitors, as well as qPCR amplification, detection and analysis. MDx-Chex for BCID2 can be used for assay verification, to track lot-to-lot performance of tests and to reduce the occurrence of incorrect results due to instrument or assay failures.

MDx-Chex for BCID2 is a patient-like full process control designed to validate the entire analytical process for sample-to-result tests. The control kit contains 43 bacteria, yeasts and antimicrobial resistance gene targets packaged in two separate vials, one for Gram (-) bacteria and one for the Gram (+) bacteria and yeasts, covering targets commonly tested for in molecular sepsis tests. The microorganisms are intact, inactivated and suspended in a matrix of stabilized red blood cells, white blood cells and blood culture media components, which is designed to challenge the lysis and purification processes just like a patient sample.
