Companion Diagnostic Tests (CDx) are in vitro diagnostic tools used to determine the suitability of a specific therapeutic product for a particular patient. These tests help identify biomarkers or genetic mutations that predict a patient's response to a drug, thus enabling personalized treatment strategies. CDx are primarily used in oncology but are increasingly being applied to other areas such as cardiology, neurology, and infectious diseases. Their main utility lies in selecting patients most likely to benefit from a given therapy, avoiding adverse effects, and optimizing treatment outcomes. As such, they play a critical role in the safe and effective use of targeted drugs.
In August 2023, Agilent received European IVDR certification for its companion diagnostic assay, aligning with the EU's updated regulatory standards. https://www.agilent.com/about/newsroom/presrel/2025/17apr-ca25010.htm”
As pharmaceutical companies continue to develop novel treatments tailored to specific genetic or molecular profiles, regulatory bodies like the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) are accelerating the approval process for these drugs. Targeted therapies offer a more precise approach to treatment by focusing on the unique genetic makeup of a patient’s disease, particularly in oncology, where tumor heterogeneity requires highly individualized solutions. Companion diagnostic tests are essential in identifying patients who are most likely to benefit from these therapies, ensuring their safe and effective use. With each new targeted therapy entering the market, there is often a corresponding need for a companion diagnostic to be developed or approved simultaneously. In 2025, BioNTech partnered with BMS to develop and commercialize BNT327, an experimental antibody targeting cancers like lung and breast cancer. BMS committed an initial $1.5 billion, with potential milestone payments up to $7.6 billion.
Technological progress in genomics and molecular diagnostics has significantly accelerated the growth of the Companion Diagnostic Tests market. Innovations such as next-generation sequencing (NGS), digital PCR, and CRISPR-based gene editing have made it possible to detect genetic mutations, expression profiles, and biomarkers with unprecedented speed, accuracy, and sensitivity. These advancements enable the development of highly specific and personalized diagnostic tests that can guide the selection of targeted therapies more effectively than ever before. In July 2023, Thermo Fisher introduced the Scalable Diomni Enterprise Software, designed to standardize and expedite molecular diagnostic testing processes. Furthermore, the decreasing cost of genomic sequencing has made these technologies more accessible, allowing broader clinical adoption and integration into routine healthcare. As a result, it is now feasible to perform comprehensive genetic profiling of patients, which facilitates the identification of precise drug targets and the development of corresponding companion diagnostics.
The high cost associated with the development and validation of companion diagnostic tests is a significant barrier to market growth. Creating a companion diagnostic requires extensive research, clinical trials, regulatory submissions, and co-development efforts alongside therapeutic drugs. This process is not only time-consuming but also capital-intensive, often demanding multimillion-dollar investments over several years. For smaller diagnostic companies, these costs can be prohibitive, limiting their ability to innovate or bring new tests to market. Moreover, the requirement to demonstrate a strong clinical association between the test and the therapeutic outcome adds an additional layer of complexity. Developers must conduct rigorous clinical validation studies to meet regulatory standards, which further increases the financial burden. Even after approval, there are ongoing costs related to compliance, quality assurance, and potential updates to the test as new scientific data emerges.

The immediate and direct impacts of these tariffs has been the increased cost burden on U.S.-based diagnostic companies. Manufacturers such as Roche, Qiagen, Thermo Fisher Scientific, and Illumina—key players in the companion diagnostics space—have had to either absorb higher costs or pass them on to consumers and healthcare providers. This has led to elevated pricing for CDx kits and potentially hindered adoption, especially among smaller healthcare providers and research labs with limited budgets. Additionally, delays in supply chain logistics and the increased cost of raw materials have slowed down innovation and commercialization timelines for new CDx products.
The Trump administration’s tariffs, many of which remain in place as of 2025, continue to reverberate through the medical diagnostics sector, particularly the high-growth Companion Diagnostic (CDx) tests segment. These tariffs introduced primarily under Sections 232 and 301 of the Trade Expansion Act targeted medical equipment and chemical components among a broader set of Chinese imports. Given that a large portion of CDx components, including reagents, plasticware, and semiconductor chips for lab instruments, are imported from China and East Asia, these tariffs have had a significant cascading effect across the value chain.
Companion diagnostic tests are co-developed with specific drug therapies and require advanced molecular testing platforms such as PCR (Polymerase Chain Reaction), NGS (Next-Generation Sequencing), and immunohistochemistry. A 25% tariff on imported lab equipment and raw materials from China has increased capital and operational expenditures for diagnostic firms. Based on recent industry surveys, the average cost of producing a CDx assay rose by 12%–15% between 2018 and 2024, with a disproportionate impact on small and mid-sized biotech firms.
The Companion Diagnostic Tests market is highly competitive, characterized by the presence of several global and regional players offering a wide range of products. Key companies in the market, such as Abbott, F. Hoffmann-LA Roche AG, Genomic Health, Inc., QIAGEN, Agilent Technologies, Inc dominate through their extensive product portfolios, strong distribution networks, and focus on innovation.
In January 2024, Agilent partnered with Incyte to develop companion diagnostics supporting Incyte's hematology and oncology portfolio, expanding Agilent's biomarker offerings. https://www.agilent.com/about/newsroom/presrel/2024/30jan-ca24002.html" In August 2023, QIAGEN obtained FDA approval for a companion diagnostic to aid therapy selection for gastrointestinal stromal tumors in collaboration with Blueprint Medicines’ AYVAKIT. https://corporate.qiagen.com/English/newsroom/press-releases/press-release-details/2023/QIAGEN-receives-FDA-approval-for-companion-diagnostic-to-Blueprint-Medicines-AYVAKIT-avapritinib-in-gastrointestinal-stromal-tumors/default.aspx/"

The usage of companion diagnostic tests in DNA detection involves advanced molecular techniques, such as polymerase chain reaction (PCR), next-generation sequencing (NGS), and fluorescence in situ hybridization (FISH). These technologies allow for precise identification of genetic alterations at the DNA level, facilitating early diagnosis, treatment selection, and monitoring of disease progression. By integrating companion diagnostics into clinical workflows, healthcare providers can make informed decisions based on a patient’s unique genetic makeup. This not only improves treatment outcomes but also reduces unnecessary exposure to ineffective therapies, ultimately enhancing the overall efficiency of healthcare delivery. In May 2025, researchers at the Indian Institute of Technology, Indore (IIT-I), developed a Quantum AI nanotechnology that enables early and accurate detection of genetic mutations, including those related to cancer. This technology integrates quantum transport with explainable artificial intelligence, offering a cost-effective, high-resolution solution for unified DNA sequencing.

According to Cognitive Market Research, Breast Cancer is likely to dominate the Companion Diagnostic Tests Market. One of the most common uses of companion diagnostic tests in breast cancer is to detect HER2 overexpression or amplification. HER2-positive breast cancers tend to be more aggressive, but they respond well to targeted therapies like trastuzumab and pertuzumab, which specifically inhibit the HER2 protein. The HER2 status is determined using immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH) tests, both of which are considered companion diagnostics because they guide the use of HER2-targeted treatments. Without these tests, patients might receive less effective chemotherapy or miss the opportunity for more precise, targeted therapies that can significantly improve survival rates. In August 2022, the FDA approved Enhertu for HER2-low breast cancer, a newly recognized subtype. This approval marked a significant step in treating patients previously considered ineligible for HER2-targeted therapies.
In the Companion Diagnostic Tests Market, the Lung Cancer segment has been expanding at a rapid pace. The use of companion diagnostics in lung cancer has revolutionized personalized medicine by enabling more precise and individualized treatment. Traditional chemotherapy, while still used, often has broad systemic effects and limited specificity. In contrast, targeted therapies guided by companion diagnostic results offer improved response rates and progression-free survival for patients with actionable mutations. For instance, patients with EGFR mutations often benefit from EGFR tyrosine kinase inhibitors (TKIs), whereas those with ALK rearrangements may respond well to ALK inhibitors. This precision approach not only enhances patient outcomes but also helps avoid the toxicities and side effects associated with non-targeted treatments. Telisotuzumab vedotin (Emrelis) approved by the U.S. FDA in May 2025, this ADC targets c-Met overexpression in non-small cell lung cancer (NSCLC) patients who have previously undergone treatment.

According to Cognitive Market Research, the Hospitals segment holds the largest market share. In hospitals, the implementation of companion diagnostic tests also enhances clinical decision-making by providing precise, evidence-based information. This not only helps in selecting the most appropriate therapy but also supports monitoring and adjusting treatment plans as needed. Additionally, the integration of these tests into routine clinical workflows facilitates faster and more accurate diagnoses, which can lead to improved patient prognosis and reduced healthcare costs by avoiding ineffective treatments. As the technology evolves, hospitals increasingly rely on companion diagnostics to guide personalized treatment approaches, making these tests a critical component of modern medical care.
In the Companion Diagnostic Tests market, Specialty Clinics is expected to be the fastest growing segment in the market. Companion diagnostic tests have become increasingly vital in specialty clinics, revolutionizing the way personalized medicine is delivered. These tests are designed to identify specific biomarkers or genetic mutations in patients, enabling clinicians to tailor treatments that are more effective and targeted. In oncology clinics, for example, companion diagnostics are commonly used to detect mutations such as EGFR or HER2, which guide the selection of targeted therapies for cancer patients. This precise approach not only improves treatment outcomes but also minimizes unnecessary exposure to ineffective drugs, reducing side effects and healthcare costs. For instance, in cardiology, tests may identify genetic markers that predict patient response to certain anticoagulants or cholesterol-lowering drugs.
