BD's GeneOhm's Cdiff assay B gene results time

BD's GeneOhm's Cdiff assay B gene results time

• A. In twenty-four hours
• B. In less than one hour
• C. In less than two hours
• D. In four hours

Answer: (C)

Turnaround time for rapid molecular diagnostics like the BD GeneOhm Cdiff assay is a key driver of their clinical value. This assay uses real-time PCR to detect the toxin B gene of toxigenic Clostridioides difficile directly from a stool sample, and the workflow is streamlined to deliver results quickly. Because the process—from sample prep through amplification and detection—is designed to be completed in one run, the practical time to result is under two hours. This rapid turnaround is much faster than traditional methods such as culture or toxin assays, which can take days, and it aligns with the need for timely decision-making in suspected C. difficile infection. While some runs may be quicker, the standard performance expectation is that results are obtained in less than two hours, making that option the most accurate reflection of typical use. Twenty-four hours or four hours would not reflect the rapid, same-day capability of this molecular test, and aiming for under one hour would be more aggressive than the assay’s typical stated workflow.
