Globally, the World Health Organization (WHO) 2023 reported that around 18 million people were living with rheumatoid arthritis (RA), with 70% of those affected being women of whom 55% were aged over 55 years. The growing prevalence of chronic and infectious diseases globally underscores the critical need for accurate, early, and accessible diagnostic tools, thereby driving the positive growth of the immunodiagnostics market during the forecast period. 

Another significant factor contributing to market growth is the rising demand for point-of-care (POC) testing. Healthcare systems worldwide are increasingly prioritizing faster and more efficient diagnostic solutions, with POC testing offering rapid results at the patient’s bedside, in remote locations, or in outpatient settings. This decentralization reduces reliance on centralized laboratories, enabling quicker clinical decision-making, particularly for infectious diseases (e.g., COVID-19, influenza, tuberculosis), chronic conditions (e.g., diabetes, cardiovascular diseases), and acute medical emergencies. 

Immunodiagnostic tests, renowned for their accuracy and reliability in detecting a variety of biomarkers (such as hormones, infectious agents, and autoimmune markers), are increasingly integrated into POC platforms. This synergy between advanced immunodiagnostic technologies and accessible POC solutions is spurring technological innovations such as microfluidic devices, biosensors, and AI-based diagnostics which are expected to further expand the immunodiagnostics market. 

Despite these growth drivers, certain market restraints persist. Stringent regulatory approval processes especially in the U.S. (FDA) and Europe (CE marking) can delay product launches. Additionally, limited availability and awareness of immunodiagnostic solutions in low- and middle-income countries (LMICs), coupled with high costs of advanced diagnostics, and may hinder widespread adoption. Addressing these barriers through regulatory harmonization, public-private partnerships, and cost-effective innovations will be crucial to unlocking the full potential of the immunodiagnostics market. 

Immunodiagnostics Market Segment Analysis:

Immunodiagnostics Market by Product (Instruments and Kits & Reagents), Type (Enzyme-Linked Immunosorbent Assay (ELISA), Radioimmunoassay, Chemiluminescent Immunoassay (CLIA), and Others), Disease (Infectious Diseases, Autoimmune Disorders, Oncological Disorders, and Others), End-User (Hospitals and Clinics, Diagnostics Centres, and Others), and Geography (North America, Europe, Asia-Pacific, and Rest of the World) 

In the type segment of the immunodiagnostics market, the Enzyme-Linked Immunosorbent Assay (ELISA) category is projected to amass a significant revenue share in 2024. ELISA remains a cornerstone diagnostic technique due to its widespread application, high sensitivity, specificity, and versatility in detecting and quantifying antigens or antibodies. Its extensive use spans the diagnosis of infectious diseases (e.g., HIV, hepatitis, COVID-19), autoimmune disorders (e.g., rheumatoid arthritis, Lupus Nephritis), cancer biomarkers, and allergen detection, making it indispensable in both clinical and research settings.  

One of the primary drivers of ELISA’s market dominance is its ability to process large sample volumes with high throughput, enabling mass screening and epidemiological studies.
