MDx-Chex® for BC-GP and MDx-Chex® for BC-GN
MDx-Chex for BC-GP and BC-GN are controls designed to evaluate the entire analytical process of the Luminex VERIGENE® BC-GP and BC-GN Panels for sepsis. With MDx-Chex for BC-GP and BC-GN, you can track lot-to-lot performance of the BC-GP and BC-GN assays and reduce the occurrence of incorrect results due to instrument or assay failures.

Product Description
MDx-Chex for BC-GP and BC-GN are patient-like full process controls designed to validate the entire analytical process of the Luminex VERIGENE BC-GP and BC-GN Panels, including automated nucleic acid extraction, DNA purification, hybridization of target DNA to the microarray, hybridization of gold nanoparticles to target DNA and silver staining of hybridized probes. MDx-Chex for BC-GP and BC-GN cover all targets tested with Luminex VERIGENE for BC-GP or BC-GN, respectively. Microorganisms are intact, inactivated and…

Features
- Patient-like matrix of inactivated microorganisms, blood cells and culture media components
- Can be directly used on the Luminex VERIGENE system
- Complete coverage of all BC-GP or BC-GN Panel targets in a single vial
- Negative controls contain only blood cells and culture media components for a true patient-like negative control
Benefits
- Challenges and verifies the entire analytical process of the Luminex VERIGENE assays
- Reduces preanalytical variables such as pipetting errors and cross-contamination
- Easy to use — simply pipette like a patient sample
