Labcorp Holdings Inc. introduced two new molecular residual disease (MRD) assays on January 13 2026: Labcorp Plasma Detect ID, a whole‑exome sequence‑guided panel for stage I–III breast cancer and stage I–IIIA non‑small cell lung cancer, and Labcorp Plasma Detect Genome, a whole‑genome MRD test for stage III colon cancer. Both tests are designed for nationwide use and aim to detect cancer recurrence earlier than conventional imaging by measuring circulating tumor DNA (ctDNA) with a limit of detection of 0.005 % (LOD95).
The clinical data underpinning the launch are compelling. Recurrence rates for the target cancers—35 % for stage III colon cancer, 10–40 % for stage I–III breast cancer, and 10–55 % for stage I–III non‑small cell lung cancer—highlight the substantial patient population that could benefit from earlier detection. Labcorp’s studies, presented at AMP 2025, demonstrated that the assays can identify minimal residual disease in patients who are clinically disease‑free, providing a tool that could guide adjuvant therapy decisions and potentially improve long‑term outcomes.
From a business perspective, the new assays reinforce Labcorp’s strategy to focus on high‑complexity, high‑margin specialty tests. The oncology mix already grows 2–3 times faster than routine diagnostics, and the addition of these liquid‑biopsy products is expected to accelerate that growth trajectory. Pricing power in the MRD space, combined with the high switching costs associated with liquid‑biopsy platforms, positions Labcorp to capture a larger share of the rapidly expanding MRD market and to differentiate itself from competitors such as Quest Diagnostics. The high‑margin nature of the assays also supports the company’s broader margin expansion goals, as the cost of reagents and instrumentation is offset by premium pricing for early recurrence detection.
Labcorp’s Q3 2025 results—revenue of $3.56 billion, up 9 % YoY, and adjusted EPS of $4.18—illustrate the company’s strong financial foundation. The oncology segment contributed significantly to that growth, and the new MRD assays are expected to add further revenue and margin lift. CEO Adam Schechter emphasized that oncology, women's health, autoimmune, and neurology are the core therapeutic areas where Labcorp has launched over 100 tests in 2025, and that these areas are projected to grow 2–3 times faster than the overall diagnostics market. The new MRD tests align with that growth narrative and provide a clear path to higher profitability.
The market opportunity for MRD testing is sizable. With recurrence rates ranging from 10 % to 55 % across the targeted cancers, the potential patient base is in the millions. Early detection of recurrence can reduce costly late‑stage treatments and improve survival, creating a strong value proposition for payers and providers. By expanding its MRD portfolio, Labcorp taps into a high‑growth niche that complements its existing liquid‑biopsy offerings and positions the company to capture a larger share of the projected multi‑billion‑dollar MRD market.
In summary, Labcorp’s launch of Labcorp Plasma Detect ID and Genome represents a strategic expansion into a high‑margin, high‑growth oncology diagnostic segment. The move strengthens the company’s specialty oncology mix, supports margin expansion, and aligns with its broader focus on high‑complexity tests that command premium pricing and create switching costs for clinicians. The announcement is a material event that will likely influence long‑term investment theses focused on Labcorp’s growth trajectory and competitive positioning in the diagnostics space.
