The RUO Immunoassay Market is expected to grow from USD 5.708 billion in 2025 to USD 10.771 billion in 2030, at a CAGR of 13.54%.
Immunoassays designated for research use only (RUO) are called RUO immunoassays and are not meant for use in diagnostic procedures. They are virtually uncontrolled and have a single intended function, which is studying. RUO immunoassays use RUO products, and these RUO products may be used in preclinical or nonclinical research settings and with either clinical or nonclinical materials. The evaluation of the possible clinical utility of a product in the early stages of development is the extent of the research for RUO immunoassays. The investigational use of RUO immunoassays (clinical investigations) and research to determine a product's safety and efficacy is prohibited. Results cannot be used to evaluate the patient's condition or for any diagnostic, prognostic, monitoring, or therapeutic reasons. They also cannot be transmitted to the patient's doctor or medical record. The confirmation of the researcher's consent that the product won't be used for clinical reasons is suggested for RUO product manufacturers and distributors.
The rising occurrences and the prevalence of infectious diseases are driving the global RUO immunoassay market growth. The use of RUO immunoassay ranges widely, from assessing biomarkers to the amounts of host cell protein contaminants in release testing to figuring out the pharmacokinetics of biologics. To assess the immunogenicity of viral vectors, for example, immunoassays are crucial in the development of novel therapies such as recombinant proteins and nanobodies, as well as in cell and gene therapy. Therefore, rising R&D activities in the field of biopharmaceuticals will further propel the demand for RUO immunoassay during the forecast period. However, difficulty in obtaining reliable data is anticipated to limit the market growth since interference reduces the effectiveness of cross-reacting antibody reagents.
The quest for effective bioanalytical methods that yield trustworthy results has accelerated in response to the drive to increase productivity in biopharma R&D, from lead discovery and preclinical/clinical trials through bioprocess development to manufacturing. This is done to instil confidence in data-driven decision-making and meet regulatory requirements. RUO immunoassays produce precise and reliable findings rapidly, with the least amount of sample and reagent use, and at the lowest possible cost. There is more time for data analysis and a lower chance of operator fatigue as a result of fewer manual procedures and hands-on time. Accordingly, the availability of a research-use-only solution for biopharmaceutical firms was revealed by Grail on January 2023. Cell-free DNA (cfDNA) obtained from peripheral blood is being analyzed by the company using a targeted methylation technology to interrogate cancer signals. Prognosis, minimum residual disease identification, and recurrence tracking across various cancer types in research studies are just a few potential research use cases, according to the company.
Immunoassays are essential tools for a variety of research fields, including basic science and biopharmaceutical research and development. Applications include determining the pharmacokinetics of biologics as well as evaluating biomarkers, host cell protein contaminants, and release testing quantities. Immunoassays used for research purposes (RUO) are often done retrospectively in batches as the trial advances and do not require the same level of validation. A mix of top-notch reagents, improved methods, and automation is required to accomplish this. For instance, the development of research or retrospective use (RUO) assay design and migration services is provided by Almac Diagnostic Services on a variety of platforms. Over the past few years, the revenue of such businesses has increased. For instance, Almac experienced a growth of about 8.6%, resulting in total sales of about £735 million in 2021, according to its annual report.
Interference should be identified early in method development by evaluating a number of parameters, including parallelism/linearity, assay type, sample size, inhibiting agents' effects, therapy and sampling methodology changes, trends, and discrepancies in the study's findings. Drug-target complex dissociation, which can be lessened by optimizing reagent concentrations and incubation/assay periods, can complicate drug-target research.
By product, the RUO immunoassay market has been classified into Radioimmunoassay (RIA), Enzyme Immunoassay or Enzyme-linked Immunosorbent Assays (ELISA), Counting Immunoassay (CIA), Fluoroimmunoassay (FIA), and Chemiluminescence Immunoassay (CLIA). The increasing prevalence of chronic diseases is being witnessed worldwide. For instance, according to the World Health Organization's key statistics on cancer, released in February 2022, approximately 400,000 children worldwide develop cancer each year.
Furthermore, the WHO predicted in its July 2022 key facts on HIV (Human Immuno Deficiency) that approximately 38.4 million people worldwide were infected with HIV by the end of the year 2021, with approximately 1.5 million new cases being recorded in 2021 alone. Hence, an increase in the number of chronic diseases drives the need for better research which could help in better clinical treatment for patients. Therefore, increasing the use of radioimmunoassay-based techniques can help to measure and even determine very small quantities of substances such as antibodies, hormones, antigens, and even drugs.
Consequently, various governments have increased their research expenditure, thereby improving their medical infrastructure. Such measures and initiatives are expected to drive the market growth for the RIA RUO immunoassay market owing to its growing importance and successful techniques.
The majority of the RUO immunoassay market is dominated by North America. In the coming years, it's expected that countries in the Asia-Pacific region will expand in this market at the fastest rate.
RUO immunoassay is used for research purposes only in non-clinical or preclinical research settings and provides necessary information for the clinical product, which is in the testing phase. The demand for such products is expected to show positive growth in the United States owing to the growing prevalence of major chronic diseases, which is boosting the demand for efficient diagnostic tools for detection purposes. This is expanding the applications of RUO immunoassays during the testing & development phase. According to the American Cancer Society, in 2024, an estimated 2,041,910 people were diagnosed with cancer.
Moreover, the nation is also witnessed several RUO-based product launches to deal with the COVID-19 pandemic. For instance, in October 2021, US-based bioresearch company Bio-Rad Laboratories launched “Bio-Plex Pro Human IgA” and “IgM SARS-CoV-2” for detecting IgM and IgA antibodies against 4 SARS-CoV-2 antigens. The product is an addition to the company’s line of qualitative multiplex immunoassays, which are used for RUO purposes only.
Favorable investments by the government to boost biopharmaceuticals and biomanufacturing are also expected to act as an additional driving factor for the RUO immunoassay market growth. In September 2022, for instance, the Department of Health and Human Services allocated US$40 million to expand the role of biomanufacturing in antibiotics and active pharmaceutical ingredients, and other key ingredients for producing essential medications. Additionally, the Centers for Disease Control and Prevention, in June 2022, announced investments of US$215 million in the country’s Cancer Moonshot program, which aims to prevent cancer through new treatment developments.
Due to its huge senior population and high frequency of infectious illnesses, Asia Pacific is anticipated to increase at the fastest rate throughout the projected period. One of the reasons propelling the market in the area is the expanding usage of cutting-edge laboratory methods and processes for quicker examination.
