MDx-Chex® for Blood Culture Yeast (RUO), MDx-Chex® for Blood Culture GP (RUO) and MDx-Chex® for Blood Culture GN (RUO)

Full-process quality controls for validation of molecular assay workflows

MDx-Chex for Blood Culture Yeast (RUO), MDx-Chex for Blood Culture GP (RUO) and MDx-Chex for Blood Culture GN (RUO) are full-process molecular quality controls designed for comprehensive molecular assay workflow validation. Each control contains intact, inactivated microorganisms suspended in a stabilized, blood-like matrix of red and white blood cells and blood culture media components, making them ideal for evaluating the entire molecular testing process, from extraction to detection. Supplied in single-use vials, these controls cover multiple microbial targets, pathogens and antimicrobial resistance markers, helping labs achieve reliable performance, streamlined workflows and confident results when they matter most.

For Research Use Only. Not for use in diagnostic procedures.  We recommend that you verify that control target coverage is adequate for your sample-to-results system of choice.

*See the Instructions For Use (IFU) for full target coverage.
