據 Mordor Intelligence 稱,2025 年伴隨診斷市場價值為 87 億美元,預計到 2031 年將達到 173.5 億美元,而 2026 年為 97.6 億美元,預測期(2026-2031 年)的複合年成長率為 12.18%。

本報告按技術(免疫組織化學、聚合酵素鏈鎖反應(PCR) 等)、適應症(肺癌、乳癌等)、產品類型(檢測和試劑盒、儀器和分析儀等)、檢體類型(組織切片檢查、液態生物檢體等)、最終用戶(製藥和生物技術公司、合約研究組織 (CRO) 等)和地區進行分類。
液態生物檢體伴隨診斷正在重新定義癌症治療管理,它提供了一種微創、可重複的檢測方法,能夠即時捕捉腫瘤的異質性。臨床醫生現在可以透過循環腫瘤DNA追蹤疾病進展,並動態調整治療方法,而不是依賴靜態的組織切片。由此,醫院檢查室需要重新考慮其檢測能力和低溫運輸物流,以應對血液檢測量的增加,這將影響整個腫瘤科的資金分配計畫。 FoundationOne Liquid CDx於2024年獲得多項FDA批准,這清楚地展現了監管力度推動其市場滲透的勢頭。然而,由於液態生物檢體的敏感性仍然會因癌症分期和腫瘤釋放機制的不同而有所差異,醫療機構不得不採用“組織和血液檢測相結合的混合策略”,以在保持診斷準確性的同時,最大限度地減少重複檢測。
伴隨診斷不再只是可選項,它已成為許多標靶治療獲得治療的法定必要條件。美國食品藥物管理局(FDA)已列出168種與已通過核准檢測相關的生物標記-藥物組合,這意味著保險報銷機構將逐步停止支付未進行分子水平確認的治療療程費用。這種關聯促使製藥公司在I期臨床試驗早期階段就與藥物研發團隊合作開發檢測方法,從而縮短整體研發週期,但同時也增加了臨床前研究的複雜性。由此直接導致合約研究組織(CRO)正在擴展其生物標記檢驗能力,以確保獲得多年戰略外包契約,從而在生物製藥研發管線中確立了自身事實上的「分子水平安全隔離網閘」地位。
伴隨診斷的研發可能需要5,000萬至1億美元的投資,耗時3至5年,因此診斷是長期資本項目。中小企業越來越依賴與大型製藥企業的合作,透過股權轉讓換取研發資金。由此產生的一個次要後果是知識產權組合的整合。隨著大型公司吸收醫療設備的專利權,新參與企業的經營自由度正在下降。這種充滿挑戰的智慧財產權環境促使創業投資人更傾向於投資擁有可擴展檢測項目的平台型公司,而非單一標誌物概念,創業投資資金的重心也正悄悄從利基生物標記轉向擴充性的、資訊科學主導的解決方案。這些結構性變化正在重塑伴隨診斷市場。
即使到了2025年,PCR仍將佔據伴隨診斷市場21.8%的最大佔有率,但NGS預計將超越所有其他技術。 NGS在伴隨診斷領域的市場規模預計將超過基於PCR的替代方案,並在2026年至2031年間以13.85%的複合年成長率成長。醫院採購委員會擴大進行總體擁有成本(TCO)分析,結果表明,高樣本處理能力可以在三年攤銷期內抵消NGS耗材成本的增加。因此,儀器供應商現在將分析軟體與試劑合約捆綁銷售,這種機制將收入確認方式從一次性硬體銷售轉向持續服務收入,並重塑了季度收入預測。
隨著聯合治療免疫療法的日益普及,黑色素瘤伴隨診斷的市場佔有率預計將在2031年之前以13.22%的複合年成長率成長。這將需要皮膚科檢查室和分子實驗室之間密切合作,以確保快速進行Reflex檢測,從而有效地融合兩個先前各自獨立的臨床領域。這種整合要求電子健康記錄供應商調整其醫囑輸入模組,以支援Reflex分子檢測專案。雖然這種IT調整表面上看起來微不足道,但實際上卻代表著整個醫療保健系統一項巨大的行政投入。
截至2025年,北美將佔據39.95%的市場。聯合健康保險公司(UnitedHealthcare)的政策是,當FDA批准的伴隨診斷試劑與相應藥物聯合使用時,保險公司會為其提供保險覆蓋。這項政策獲得了其他保險公司的支持,直接影響了這些試劑的普及速度。因此,預計聯合健康保險公司以外的其他私人保險公司也可能效仿這項政策,以保持自身競爭力。這將引發連鎖反應,從而穩定整個產業的檢測報銷率。
預計2026年至2031年,亞太地區的複合年成長率將達到12.45%。日本政府支持的癌症基因組分析(CGP)計畫預計到2035年市場規模將達到540億日圓,將推動日本國內檢測實驗室定序能力的提升。這項政府措施將為鄰國樹立先例,協調監管預期,促進跨境臨床試驗的參與,並加速對研究不足的亞洲人群的數據累積。
歐洲體外醫療設備法規 (IVDR) 的環境正迫使企業重新思考其產品上市策略。認證實驗室有限的處理能力增加了市場風險,導致診斷設備製造商考慮將集中檢測模式作為臨時解決方案。然而,這種集中化可能會無意中強化某些參考實驗室的地位,並形成準寡占,從而在檢測量高峰期影響定價。
According to Mordor Intelligence, the companion diagnostics market size was valued at USD 8.70 billion in 2025 and estimated to grow from USD 9.76 billion in 2026 to reach USD 17.35 billion by 2031, at a CAGR of 12.18% during the forecast period (2026-2031).

This report is Segmented by Technology (Immunohistochemistry, Polymerase Chain Reaction, and More), Indication (Lung Cancer, Breast Cancer, and More), Product Type (Assays and Kits, and Instruments and Analyzers, and More), Sample Type (Tissue Biopsy, Liquid Biopsy, and More), End-User (Pharmaceutical and Biotechnology Companies, Contract Research Organizations (CROs), and More), and Geography.
Liquid biopsy companion diagnostics are redefining cancer management by providing a minimally invasive route for repeat testing that captures tumor heterogeneity in real time. Clinicians now track disease evolution through circulating tumor DNA, dynamically adjusting therapy rather than relying on static tissue snapshots. A second-order implication is that hospital laboratories must recalibrate throughput and cold-chain logistics to accommodate larger volumes of blood-based assays, affecting capital-allocation timelines across the entire oncology service line. FoundationOne Liquid CDx, granted multiple FDA approvals in 2024, illustrates the regulatory momentum that is quickening market uptake . Yet liquid biopsy sensitivity still varies by cancer stage and by tumor shedding biology, meaning providers are pressured to adopt hybrid tissue-plus-blood strategies that preserve diagnostic accuracy while controlling test redundancy.
Companion diagnostics have moved beyond optional add-ons; they are codified prerequisites for access to many targeted drugs. The FDA lists 168 biomarker-drug pairings linked to approved tests, signaling that reimbursement agencies will progressively withhold payment for therapy courses lacking molecular confirmation. This linkage is steering pharmaceutical companies to co-develop tests earlier in Phase I trials, compressing total program timelines but increasing preclinical complexity. An immediate knock-on effect is that contract research organizations (CROs) are expanding biomarker-validation benches to secure multi-year strategic outsourcing contracts, positioning themselves as de facto molecular gatekeepers for biopharma pipelines.
Developing a companion diagnostic can require USD 50-100 million and 3-5 years, framing diagnostics as long-cycle capital projects. Smaller firms increasingly tie their fortunes to big-pharma alliances, trading equity stakes for developmental funding. The second-order consequence is a consolidation of intellectual-property portfolios: as large companies absorb device rights, freedom-to-operate for newcomers narrows. This tightening IP landscape nudges venture investors to favor platform companies with expandable assay menus rather than single-marker concepts, subtly migrating venture dollars away from niche biomarkers toward scalable informatics-driven solutions, these structural shifts are shaping the companion diagnostic market.
Other drivers and restraints analyzed in the detailed report include:
For complete list of drivers and restraints, kindly check the Table Of Contents.
PCR still owns the largest 2025 slice at 21.8% of the companion diagnostic market share, yet NGS is expected to outpace all other technologies. NGS market size in companion diagnostics is forecast to outpace PCR-based alternatives, expanding at 13.85% CAGR between 2026-2031. Hospital procurement committees increasingly run total-cost-of-ownership analyses that reveal high sample throughput offsets higher NGS consumable costs over a three-year amortization window. Consequently, instrument vendors now bundle analytics software into reagent contracts, an arrangement that shifts revenue recognition from one-time hardware sales to recurring service streams-reshaping quarterly earnings visibility.
Melanoma companion diagnostics will capture a market share acceleration to 13.22% CAGR through 2031 as immunotherapy combinations proliferate. The downstream impact is that dermatology clinics must coordinate closely with molecular labs to ensure rapid reflex testing, effectively blending two historically separate clinical silos. This integration forces electronic medical record vendors to adapt order-entry modules to accommodate reflex molecular panels, an IT adjustment that, although minor on the surface, represents a notable administrative investment across health systems.
North America holds 39.95% market share in 2025. UnitedHealthcare's policy to cover FDA-approved companion diagnostics when matched with the corresponding drug signals payer endorsement that directly influences adoption velocity. An inferred outcome is that private insurers outside the UnitedHealthcare umbrella may emulate the policy to remain competitive, leading to a cascade that can stabilize test reimbursement rates industry-wide.
Asia-Pacific is projected to log a 12.45% CAGR from 2026-2031. Japan's government-supported cancer genome profiling (CGP) program forecasts a 54 billion-yen CGP market by 2035, prompting domestic labs to scale sequencing capacity. This governmental commitment sets a precedent that neighboring countries may replicate, harmonizing regulatory expectations and spurring cross-border clinical-trial enrollment that accelerates data accumulation in under-studied Asian populations.
Europe's In Vitro Diagnostic Regulation environment is prompting companies to reexamine launch strategies. The limited capacity of notified bodies amplifies time-to-market risk, causing diagnostic firms to consider centralized testing models as interim solutions. Such centralization may inadvertently strengthen select reference laboratories, creating a quasi-oligopoly that could sway pricing dynamics once test volumes peak.
