The U.S. autoimmune disease diagnostics market is driven by the growing incidence of autoimmune diseases like rheumatoid arthritis and multiple sclerosis, increases the need for early and accurate diagnostic testing.
Autoimmune diseases are a group of disorders that result from a modification of immune tolerance, distinguished by the formation of autoantibodies and the ensuing development of heterogeneous clinical manifestations. Diagnosing autoimmune diseases is generally a complicated process, and the available prognostic tools are limited. An area of intense research is defining why the immune system turns against its host. Research has greatly advanced the understanding of autoimmunity, and the scientific discovery from these investigations is assisting in producing the latest clinical laboratory studies of patients to aid in diagnoses.
• In February 2023, CerraCap Ventures disclosed a strategic investment in Predicta Med, one of the world's leading early startups, helping medical clinics and institutions identify and work up immune-related diseases earlier.
Major Trends in the U.S. Autoimmune Disease Diagnostics Market
- There is a shift towards personalized medicine which significantly shapes the importance of autoimmune disease diagnosis. This eventually has been boosted by advancements in molecular diagnostics and genomic data integration, which enable monitored treatment strategies derived on individual patient profiles.
- Innovative steps were taken which is directing the healthcare professionals to provide more precise interventions, bolstering the requirement for customized diagnostic tests in the autoimmune disease industry.
- Moreover, there is an increasing need of point-of-care testing (POCT) in autoimmune disease diagnostics. The preference for POCT devices stems from their ability to provide rapid results and convenience, allowing for diagnosis and management of autoimmune conditions at a real time.

Role of Artificial Intelligence in the U.S. Autoimmune Disease Diagnostics
Artificial Intelligence is being applied in the growing field of precision medicine. Precision medicine uses specific patient characteristics and health information to design treatments most likely to help that individual. Precision medicine is an increasing field in cancer treatment, where AI enables earlier diagnosis, new drug discovery, and innovation for more targeted approaches to research and care.
Machine learning allows us to determine vast amounts of data and carry out complex calculations with ease and minimal effort. For example, AI systems detect early signs of diseases such as cancer from radiographic images, often more precisely than human radiologists. AI is helping researchers and healthcare providers decipher this complexity by finding the multiple target inflammatory pathways that trigger autoimmune diseases. This will help healthcare providers better understand diagnoses, disease progression, and treatment.
Segment Insights
Type Insights
The localized autoimmune disease diagnostics segment dominated the U.S. autoimmune disease diagnostics market with the largest share in 2024. It deals with autoimmune diseases primarily affecting specific organs or tissues, like localized scleroderma or autoimmune thyroid disorders. These conditions need specific treatments involving the usage of immunosuppressants, biologics, and local intervention injections in certain cases.
- Nearly 1 million people in the United States are affected by multiple sclerosis.
The systemic autoimmune disease diagnostics segment is the fastest growing in the U.S. autoimmune disease diagnostics market during the forecast period. The increasing technological advancements, rising need for systemic autoimmune disease diagnostics, and supportive government policies. Systemic autoimmune disease diagnostics are further bifurcated into rheumatoid arthritis, systemic lupus erythematosus (SLE), etc. Many key players compete for market leaders in an extremely competitive landscape, ranging from established industry giants to innovative startups.
Test Type Insights
The antinuclear antibody tests segment dominated the U.S. autoimmune disease diagnostics market share in 2024. Antinuclear antibody tests are considered a cornerstone in the autoimmune diagnostics market in the United States, primarily due to their critical role in determining autoimmune disorders such as rheumatoid arthritis and systemic lupus erythematosus. The transformation of testing technologies that includes ELISA and immunofluorescence assays, has improved the efficiency and accuracy. Such advancements have defined laboratory workflows and enhanced diagnostic precision.
End-use Insights
The hospitals segment dominated the U.S. autoimmune disease diagnostics market in 2024. With the rise in autoimmune disorders such as rheumatoid arthritis, lupus, and multiple sclerosis, more accurate testing techniques, such as blood tests, biopsy procedures, and imaging techniques, are being used in hospitals. The need for hospitals to utilize advanced equipment in diagnosing autoimmune diseases through specialized diagnostic equipment and well-developed health infrastructure promotes the growth of autoimmune disease diagnostics.
The diagnostic centers segment is the fastest growing in the U.S. autoimmune disease diagnostics market during the forecast period. Diagnostic centers are increasingly adopting advanced imaging techniques and laboratory automation, improving the accuracy and efficiency of autoimmune disease detection. Collaborations between diagnostic centers and research institutions are expanding the range of available tests.
