MDx-Chex for CT/NG/TV is a full-process molecular quality control designed for the comprehensive validation of molecular assays that identify Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) and Trichomonas vaginalis (TV). Each control contains intact, inactivated microorganisms suspended in a stabilized, patient-like matrix of red blood cells and epithelial cells to evaluate entire molecular testing process, from extraction to detection.
For Research Use Only. Not for use in diagnostic procedures.
Patient-like matrix of inactivated microorganisms, blood cells and epithelial cells
Can be directly used on sample-to-answer platforms
Can be used with multiple assays*
<em>*We recommend that you verify that control target coverage is adequate for your sample-to-results system of choice. </em>
Room temperature stability eliminates freeze-thaw cycles and pooled targets reduce number of cartridges needed per control run
Single-use vials reduce preanalytical variables such as pipetting errors and cross-contamination
Easy to use – simply pipette like a patient sample

MDx-Chex for CT/NG/TV is a full-process molecular quality control designed for the comprehensive validation of molecular assays that identify Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) and Trichomonas vaginalis (TV).

No, MDx-Chex for CT/NG/TV is for Research Use Only and not for use in diagnostic procedures. This control is intended for research applications and validation of molecular assay workflows that detect sexually transmitted infections.
MDx-Chex for CT/NG/TV contains a patient-like matrix of inactivated microorganisms, red blood cells and epithelial cells that mimics actual patient specimens from urogenital sites. This composition challenges the entire molecular testing workflow including sample preparation, nucleic acid extraction and detection, ensuring that quality control evaluates the complete procedure as it would be performed on real patient samples rather than only testing the detection step.
Yes, MDx-Chex for CT/NG/TV can be directly used on sample-to-answer platforms and with multiple assays. However, we recommend that you verify that control target coverage is adequate for your sample-to-results system of choice before implementing the control in your workflow.
MDx-Chex for CT/NG/TV is supplied in single-use vials with room temperature stability. The single-use format eliminates concerns about contamination or degradation after opening, while room temperature stability eliminates freeze-thaw cycles that can degrade nucleic acids and affect control performance.
MDx-Chex for CT/NG/TV uses pooled targets in a single control formulation, meaning all three pathogens (CT, NG and TV) are present in one vial. This reduces the number of cartridges or test runs needed per control session compared to running separate controls for each pathogen, saving time and reducing costs.
Single-use vials reduce preanalytical variables such as pipetting errors and cross-contamination that can occur with multi-use controls. Each vial provides a fresh, uncontaminated sample that can be pipetted directly like a patient sample, ensuring consistent quality control performance and eliminating concerns about contamination between uses.
Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) and Trichomonas vaginalis (TV) are the three most common curable sexually transmitted infections. They are often tested together in multiplex molecular assays because co-infections are common, symptoms can overlap and early detection and treatment are critical for preventing complications and transmission. MDx-Chex for CT/NG/TV provides quality control for all three pathogens in a single control material.
