Bio-Rad’s ddPCR expansion (acquisition + portfolio launch): what changed and why it matters
Executive summary
What Bio-Rad did. On July 7, 2025, Bio-Rad announced an expansion of its Droplet Digital PCR (ddPCR) offering built around two pillars: (1) a strategic acquisition of Stilla Technologies and (2) the launch of four ddPCR platforms, notably the QX Continuum™ and the QX700™ series. The move broadens Bio-Rad’s instrument lineup (now spanning QX200™, QX600™, QX ONE™, QXDx™, QX Continuum™, and QX700™ variants) and is paired with a very large assay catalog to smooth migration from qPCR to ddPCR.
Why it matters. ddPCR provides absolute quantification, higher sensitivity, and superior reproducibility versus qPCR, while offering faster, simpler, and more cost-effective workflows than many NGS workflows for targeted, quantitative questions. Bio-Rad’s updated portfolio explicitly targets that middle ground—rare allele detection, precise CNV calling, residual disease/viral reservoir monitoring—and positions ddPCR as a routine tool in research and clinical labs.
What was announced (and when)
-
Acquisition & platform rollout (July 7). Bio-Rad introduced QX Continuum™ (all-in-one, qPCR-like workflow, four-color multiplexing, up to 8 thermal profiles/plate) and the QX700™ series (E/S/HT) featuring seven-color multiplexing, continuous loading, >700 samples/day, and flexible throughput tiers. These instruments complement the existing QX200/QX600/QX ONE/QXDx portfolio.
-
Webinar (Aug 26). Management hosted an investor/analyst webinar on Aug 26, 2025 (10:00 am PT) to walk through the technology, portfolio positioning, and Q&A.
Portfolio at a glance (and who each system is for)
-
QX Continuum™ – entry/bridge system for academic & translational groups moving from qPCR; run 1–96 samples on standard qPCR plates with the lowest per-sample running cost (same cost whether 1 or 96 wells), easing plastics/inventory burden. Ideal when you want qPCR-like simplicity with ddPCR accuracy.
-
QX700™ series (E / S / HT) – integrated, scalable line with highest multiplexing (7-color) and formats matched to 48 / 192 / 384 samples; >700 samples/day possible in high-throughput contexts (biopharma QA/QC, environmental testing, cell & gene therapy).
-
QX600Dx™ / QXDx™ – registered systems aimed at clinical/LDT labs, including hematologic and solid-tumor monitoring (liquid biopsy) use cases; the deck explicitly maps platform families to Clinical/LDT and BioPharma QA/QC segments.
Positioning map. The 18-page deck shows where each platform lands across entry-level, high-performance research, clinical/LDT, and QA/QC lanes, underscoring a “no-compromise coverage” strategy for all ddPCR use cases.
Why scientists care: the technical and practical deltas
1) Absolute quantification & sensitivity (core ddPCR value).
ddPCR’s partitioning into droplets enables absolute copy number measurements without standards, rare-variant detection, and highly reproducible quantitation across labs. The deck cites independent metrological work and >12,000 publications demonstrating real-world sensitivity, precision, and reproducibility—attributes that matter for MRD, viral reservoir work, and biosurveillance.
2) Fit-for-purpose vs qPCR and NGS.
Compared to NGS, ddPCR offers lower cost, shorter TAT, and simpler analysis for targeted questions; compared to qPCR, it reduces variability, avoids standard curve drift, and reaches rare-event regimes qPCR struggles with. The deck frames ddPCR as the right tool when high sensitivity, absolute measurements, and reproducibility are required.
3) Migration friction is low (assays, plastics, workflows).
Bio-Rad highlights ~490k+ validated assays (with detailed counts for CNV, mutation, gene expression, methylation, infectious disease, cell & gene therapy) and notes ~600k assays designed for qPCR are compatible with ddPCR, making it straightforward to port assays you already trust. Continuum’s use of standard qPCR plates eliminates new-plastic hassles.
4) Throughput & multiplexing choices.
From single-sample to hundreds/day, the refreshed lineup covers low- to high-throughput labs and scales multiplexing from 4-color (Continuum) to 7-color (QX700 series), letting labs right-size instrument capex and consumable pull-through.
Where Bio-Rad sees ddPCR going next
Adoption curve & markets. The deck sizes the absolute-quantitation segment at roughly $600M today, with growth driven by (i) expanding use alongside qPCR/NGS where unmet sensitivity/precision needs remain, and (ii) proven clinical utility pushing ddPCR toward routine diagnostics.
Applications spotlight. Oncology liquid biopsy monitoring, biopharma production/QA (dose control, contamination), and bio-surveillance (e.g., wastewater) are highlighted as “save-lives” applications that prize reproducibility and precision.
Assay/menu strategy. Beyond internal assay design, Bio-Rad references external partnerships to expand clinical menus (e.g., colorectal cancer screening and transplant monitoring programs cited on the webinar), signaling a roadmap to more registered tests through 2026–2027.
Practical implications for labs
For research groups (migrating from qPCR).
-
Start with QX Continuum™ to keep plates, plastics, and per-sample cost familiar while gaining ddPCR accuracy; it’s designed to look and feel qPCR-like.
-
Port your existing assays: large validated menus and qPCR↔ddPCR compatibility minimize method-development time.
-
Scale up to QX700 E/S/HT if you need 7-color multiplexing or high throughput for screening or production workflows.
For clinical/LDT labs.
-
Use registered platforms (QX600Dx / QXDx) to support oncology monitoring (liquid biopsy) and related quantitative assays where absolute measurements and lot-to-lot reproducibility are critical for patient management.
-
Expect gradual adoption: the webinar candidly notes the slow cycle for replacing entrenched, validated, reimbursed methods—so pair platform adoption with a menu strategy and evidence roadmap.
“When should I choose ddPCR over qPCR or NGS?”
-
Choose ddPCR when you need absolute copies (no standards), rare-variant detection, tight CVs across sites, rapid TAT, and cost control for targeted questions (MRD trendlines, viral reservoir quant, CNV precision, low-level contamination).
-
Choose qPCR for fast, low-cost relative quant where the biology tolerates higher variability and less sensitivity.
-
Choose NGS for discovery, high-plex variant surveys, or when you need genome-scale context—and accept longer TAT, higher cost, and heavier bioinformatics.
Evidence & credibility signals to watch
-
Peer-reviewed usage: >12,000 publications span research and a growing share of clinical application papers.
-
Metrology: the deck cites independent inter-lab reproducibility supporting droplet partitioning as the precision benchmark.
-
Company follow-through: Bio-Rad publicly committed to portfolio depth and discussed assay/menu expansion on the August 26 webinar; investor materials remain available via IR.
Risks & adoption hurdles (from Bio-Rad’s own remarks)
-
Clinical adoption is slow—replacing validated, reimbursed methods takes time and evidence; markets into 2026 remain macro-uncertain.
-
Forward-looking: All guidance is subject to change; Bio-Rad flags typical market, regulatory, supply chain and competitive risks in its safe-harbor statements.
Bottom line for potential adopters
-
If you’re qPCR-centric: the QX Continuum™ offers a low-friction on-ramp—same plates, lowest per-sample cost, and absolute quantification to improve rigor and sensitivity in familiar assays.
-
If you’re scaling quant or QA/QC: QX700™ variants provide 7-color multiplexing and throughput headroom (to >700 samples/day) to industrialize targeted quantitation.
-
If you’re clinical: align platform choice with registered systems and plan evidence generation for utility + reimbursement, leveraging Bio-Rad’s growing assay/menu ecosystem.

Here’s the same payor-facing one-pager rewritten in paragraph format so it reads as a polished briefing note rather than a bullet summary:
Why Payors Should Care About Bio-Rad’s Expanded Digital PCR Portfolio
Bio-Rad, a leader in molecular diagnostics, has recently expanded its Droplet Digital PCR (ddPCR) offering with new platforms (QX Continuum™, QX700™ series) and through a strategic acquisition that strengthens its technology base. The result is a broad, tiered portfolio that makes ddPCR more accessible to both research and clinical laboratories. For payors, this matters because ddPCR is no longer a niche platform; it is positioned to become a routine tool in oncology, transplantation, infectious disease, and cell and gene therapy monitoring—areas that already represent significant spend and reimbursement pressure.
The importance of this development lies in ddPCR’s ability to fill a precision gap between qPCR and NGS. While qPCR remains inexpensive and fast, it is limited by variability and poor sensitivity for rare variants. NGS, in contrast, is comprehensive but expensive, slow, and analytically complex. ddPCR offers a middle path, providing absolute quantification, high reproducibility, and rare-variant sensitivity at a fraction of the cost of NGS and with turnaround times closer to qPCR. For payors, this means that in many targeted applications ddPCR may substitute for more costly sequencing tests, reducing overall claims burden without compromising accuracy.
The clinical use cases for ddPCR are broadening rapidly. In oncology, ddPCR enables monitoring of minimal residual disease, quantitative tracking of circulating tumor DNA, and precise measurement of therapy response. In transplant medicine, it supports donor-derived cell-free DNA monitoring to detect rejection earlier and more reliably. In infectious disease, it provides precise quantification of viral reservoirs in HIV, HBV, and SARS-CoV-2, where qPCR often falls short. In cell and gene therapy, it is used for copy number validation, dose monitoring, and contamination detection, making it directly relevant to the emerging high-cost therapies payors must manage. These are all coverage-sensitive areas where ddPCR’s reproducibility can reduce downstream costs from false negatives, unnecessary repeat testing, or inappropriate therapy changes.
The evidence base supporting ddPCR is unusually strong. More than 12,000 peer-reviewed publications validate its reproducibility and sensitivity across a wide range of applications. Independent metrology studies confirm that droplet partitioning delivers superior reproducibility compared to qPCR, an important signal of reliability for reimbursement decisions. Bio-Rad has also positioned clinical-grade platforms (QX600Dx, QXDx) for regulated use, with oncology and transplant assays already in use and expanded menus in development. For payors, this reduces the risk of reimbursing “experimental” technology and provides confidence that ddPCR tests are supported by a credible body of evidence.
Adoption barriers are also lower than in previous technology transitions. Bio-Rad has built a catalog of hundreds of thousands of validated assays, many directly compatible with qPCR designs. The QX Continuum™ system accepts standard qPCR plates and delivers the lowest per-sample consumable cost in the ddPCR space, allowing labs to adopt the technology without overhauling workflows or inventories. At the same time, high-throughput options such as the QX700™ series can process more than 700 samples per day, making ddPCR suitable for reference and central labs. These features mean payors can expect faster laboratory uptake, translating into earlier claims activity.
In summary, Bio-Rad’s expansion of its ddPCR portfolio signals a significant shift: digital PCR is moving from specialized research toward routine clinical practice. For payors, the implications are clear. Coverage requests for ddPCR-based tests will increase, particularly in oncology, transplant, and advanced therapy monitoring. ddPCR offers a cost-effective alternative to NGS for many quantitative applications, and its reproducibility makes it a strong candidate for demonstrating clinical utility. Payors who establish frameworks for ddPCR coverage now will be better prepared to manage its adoption in a way that balances patient access, clinical benefit, and cost containment.

Here's a nerdy extrapolation.
Medicare is a large part of the oncology marketplace, and has a National Coverage Determination NCD 90.2, on NGS in Oncology, which places restrictions on the use, especially the serial use, of NGS. However, ddPCR is not NGS and ddPCR tests are exempt from the rules of NCD 90.2 Discuss why this may matter to clinicians and others.
###
That’s a very astute observation. Here’s how I’d frame it clearly for clinicians, payors, and policy readers:
Why ddPCR’s Exemption from
NCD 90.2 Matters
Background.
Medicare’s National Coverage Determination (NCD) 90.2 sets strict boundaries around next-generation sequencing (NGS) in oncology, particularly limiting coverage for repeat or serial use of NGS in the same patient. The intent was to control cost and ensure NGS is applied in situations with clear clinical utility—typically initial genomic profiling for advanced cancer. However, the NCD applies only to NGS technologies, not to other molecular methods. Because digital PCR (ddPCR) is not classified as NGS, ddPCR-based tests are not restricted by the rules of NCD 90.2.
Why this matters to clinicians.
Oncologists often need to track a single known variant or biomarker over time—for example, monitoring minimal residual disease, watching for resistance mutations, or quantifying ctDNA to assess therapy response. Under NCD 90.2, ordering repeated NGS panels is difficult, expensive, and sometimes non-covered. ddPCR provides a precise, low-cost, reimbursable alternative for longitudinal monitoring without running afoul of NCD rules. Clinicians can therefore continue to manage patient care with high sensitivity and reproducibility, while avoiding denials linked to inappropriate serial NGS use.
Why this matters to payors.
For Medicare and commercial payors, the ddPCR exemption has two important implications. First, it means that oncology monitoring tests built on ddPCR can bypass NCD 90.2 restrictions, potentially gaining easier coverage through local MAC or MolDx determinations. Second, ddPCR provides a cost-control mechanism: instead of repeat $3,000–$5,000 NGS panels, a lab can offer a focused ddPCR assay at a fraction of the price, while still delivering the clinical information needed. This positions ddPCR as a more economically sustainable technology for repeat testing in chronic oncology management.
Why this matters to the broader ecosystem.
For labs, the exemption creates regulatory headroom to innovate ddPCR-based assays without being bound by the national restrictions that weigh down NGS. For biopharma, it opens the door to companion monitoring tests that can be reimbursed on a per-use basis, rather than being constrained to a single test per patient lifetime. For patients, it means access to serial, sensitive monitoring that can guide therapy adjustments in real time.
Bottom line.
ddPCR’s exemption from NCD 90.2 turns it into a strategic tool: clinicians get flexibility, payors get cost control, and labs/biopharma get a reimbursement pathway not tied up in NGS policy constraints. In effect, it creates a “green lane” for oncology monitoring that is clinically necessary but financially and regulatorily impractical to manage with NGS alone.
