Which statement best describes the scope of tumor-specific variants tracked by Precise MRD?

• A. Up to 50 variants
• B. Up to 500 variants
• C. Up to 1,000 variants
• D. Up to 5,000 variants

Answer: (C)

Precise MRD detects residual cancer by following a broad set of tumor-specific mutations identified in the patient’s tumor. The more variants you track, the better you can detect tiny amounts of remaining cancer cells because you cover more of the tumor’s mutational diversity. Tracking up to 1,000 variants provides substantial breadth to catch heterogeneous clones without requiring impractically deep sequencing or excessive costs. Too small a panel might miss residual cells carrying untracked mutations, while a vastly larger panel would increase sequencing demands with diminishing returns. So, the best description is that Precise MRD monitors up to 1,000 tumor-specific variants.
