Methodology

How the estimates were built: data sources, modelling approach and validation steps.

Research approach

A market size is a claim about the world, and a claim is only as good as the route to it. Every study is built upward from units and prices — what is actually produced, sold or performed, at what it actually changes hands for — rather than from a headline figure divided downwards. Disclosed company revenue is then used to check that build, not to produce it.

Market size estimation, this report

The estimate is built upward from the number of liquid biopsy tests run each year across companion-diagnostic, treatment-monitoring, recurrence and screening use, multiplied by the realized price per test in each channel, since price differs sharply between a reimbursed companion-diagnostic panel and a research-use assay. Test volumes are anchored to disclosed sample throughput and testing-center capacity for the largest commercial laboratories. That bottom-up build is then checked against the disclosed oncology testing revenue reported by the public suppliers named in this report. Where the two disagreed, for example on urine and other biofluid volumes with thinner public disclosure, the bottom-up test-count assumption was the figure corrected, not the revenue check.

The four stages

The same sequence runs behind every published study, whatever the industry. The order matters as much as the steps: the segment axes are fixed before any number is collected, so the model is never reshaped to fit whatever data happens to turn up.

What the build rests on, and what checks it

The two are not interchangeable. The left column produces the number; the right column tests it. When the check disagrees with the build, the answer is to find which bottom-up assumption is wrong — a unit count, a price, a take-up rate — not to split the difference between them.

The bottom-up build rests on
  • Volume actually transacted — units produced, installed, dispensed or procedures performed, counted at the level each is genuinely recorded
  • Realised pricing by tier and channel, rather than one blended average applied across the whole market
  • Take-up and frequency: how much of the addressable base buys, and how often it repeats
The build is checked against
  • Disclosed revenue of the companies serving the market, where filings separate it far enough to be usable
  • Buyer-side spending totals — capital budgets, procurement lines, or the output of the end market the product is bought against
  • Trade and customs flows, where the product crosses borders in a separately recorded form

Data sources

Published data establishes what happened. Only the people transacting in a market can say why, and what is about to change — so the two are collected separately and weighted differently.

Primary — who is interviewed
  • Commercial and product leadership at the companies that supply the market
  • Procurement and specification leads at the organisations that buy it
  • Distributors, integrators and channel partners, where the market is served indirectly
  • Regulatory and standards specialists, where approval governs what can be sold at all
Secondary — what is read
  • Company filings, annual reports and investor disclosure
  • Government statistics, customs records and regulatory registers
  • Trade association output and standards-body publications
  • Technical and peer-reviewed literature, where the market rests on a clinical or engineering claim
Primary research design, this report

Primary interviews target laboratory directors and molecular pathology heads who set which liquid biopsy panels a hospital or reference lab adopts, procurement and managed-care contracting staff who negotiate payer coverage, and regulatory affairs leads at diagnostic manufacturers who track companion-diagnostic clearance timelines. Clinical trial operations staff at pharmaceutical sponsors are also sampled, since their patient-stratification and monitoring protocols drive a growing share of test volume outside routine clinical care. Sampling weights toward the United States and Western Europe, where companion-diagnostic reimbursement is most established, with a smaller but deliberate sample in China and Japan to capture the fastest-adopting Asia Pacific testing centers.

Secondary sources, this report

Desk research draws on the FDA's companion-diagnostic device approval and premarket-approval listings, which record which liquid biopsy assays are cleared for which drug label; the CPT and HCPCS molecular pathology billing codes and the MolDx local coverage determinations that set Medicare reimbursement for specific assays; and clinicaltrials.gov records of trials that specify a named liquid biopsy test as a stratification or monitoring biomarker. European in-vitro diagnostic registration filings under the IVDR supplement the US-centric approval data. Peer-reviewed assay validation studies, read for reported sensitivity and sample-volume requirements, fill in technical detail the regulatory filings do not disclose.

Desk research runs across proprietary research databases including Factiva, OneSource and Hoovers alongside the public sources above. Modelling and statistical validation are run in SAS and SPSS.

Forecasting

The forecast is not a growth rate applied to a base year. It is built from the drivers that are expected to change, each one stated so a reader can disagree with it.

Forecast approach, this report

The forecast carries forward the shift from single-biomarker assays toward multi-gene panels, and from late-stage treatment selection toward earlier recurrence monitoring and screening, at the pace those uses have cleared regulatory and reimbursement hurdles historically. Panel pricing is assumed to keep falling as sequencing throughput improves, and that decline is treated as the main lever widening addressable test volume, not any single new approval. The period immediately after 2020 is normalized for the disruption to routine cancer screening and elective diagnostic visits, so that dip is not read as a change in underlying demand. The forecast holds only if reimbursement for recurrence and screening indications continues to broaden at roughly its recent pace.

Triangulation and validation

No figure enters a report on the strength of one source. Where the two sizing routes disagree the difference is not averaged away — the assumption causing it is isolated, tested against a third independent measure, and either corrected or carried forward as a stated limitation. Historical years are back-tested against the growth actually recorded before any forecast is allowed to run forward from them.

Validation, this report

Historical figures are back-tested against recorded year-on-year growth in the largest disclosed oncology testing businesses to confirm the built-up volumes do not imply faster growth than those companies actually reported. Segment share shifts, particularly the move toward multi-gene panels and away from single-gene assays, were reviewed against the same laboratory-director interviews used for primary research instead of being accepted from the volume model alone. Sensitivities were run on reimbursement timing for screening and recurrence indications and on panel-price decline, since those two assumptions move the forecast further than any single driver. A slower reimbursement path than assumed here would compress the later forecast years without changing the early-year figures.

Confidence and limitations

Where an estimate is firm and where it is not is stated rather than left to be inferred from the precision of the number.

Confidence framing, this report

Confidence is firmest in the companion-diagnostic and treatment-monitoring segments, where disclosed assay volumes and payer coverage decisions are directly observable. It is thinner in early cancer screening and in urine and other biofluid testing, where commercial volume is still small and less consistently disclosed. A material change in payer coverage for multi-cancer screening, or a large diagnostic manufacturer disclosing volumes well outside the range assumed here, would be grounds to revise the estimate. This market is sized as medium confidence: triangulated from proxy volumes and adjacent disclosures rather than anchored directly to every named company's own reported liquid biopsy revenue.
