North America dominated the market, holding a significant market share of over 39.7% in 2024. Rising focus on improving patient outcomes, advancements in diagnostic technologies, collaborations and partnerships among major players, and the need for accurate diagnostic solutions represent some of the factors contributing to the autoimmune disease diagnosis market share.

The market is growing due to several key drivers. The rising global incidence of autoimmune disorders like rheumatoid arthritis, lupus, and multiple sclerosis has increased the need for accurate diagnosis. Awareness among patients and healthcare providers has improved, prompting earlier testing and treatment. Technological advancements, especially in biomarker discovery and imaging, allow faster and more precise detection. Aging populations are more prone to autoimmune conditions, which further fuels demand. There's also increased investment in research and development, leading to better diagnostic tools. Expansion of healthcare infrastructure in emerging markets has improved access to testing services. In addition, the growing use of point-of-care testing and automation in labs helps reduce turnaround time, making diagnosis more efficient. These combined factors are pushing the market forward and encouraging innovation across diagnostic platforms.

In the United States, efforts to improve early detection of autoimmune disorders like lupus and rheumatoid arthritis are gaining pace through new multi-biomarker assays. These tools aim to raise diagnostic sensitivity by targeting markers such as TC4d, TIgG, and TIgM, signaling a shift toward more precise, blood-based testing methods in clinical immunology. For instance, in January 2025, Exagen Inc. received conditional approval from the New York State Department of Health for its new biomarker assays to enhance the detection of lupus and rheumatoid arthritis. The assays, set to be added to the AVISE CTD platform, were designed to improve diagnostic sensitivity using biomarkers like TC4d, TIgG, and TIgM.

Autoimmune Disease Diagnosis Market Trends:

Advancements in Diagnostic Technologies

New biomarkers like autoantibodies are discovered to diagnose specific autoimmune diseases like lupus, rheumatoid arthritis, and celiac disease. For instance, epidemiological studies have shown that the incidence (rate of new cases) of global autoimmune diseases has risen yearly by 19.1% with rheumatological diseases such as Sjogren's and lupus rising 7.1% per year. Biomarkers can provide more precise classification and early identification of autoimmune diseases. More individualized diagnostics are allowing for the discovery of distinct protein signatures or metabolic profiles linked to autoimmune disorders only because of developments in proteomics and metabolomics. Furthermore, microarray technology allows simultaneous testing of multiple biomarkers, which makes it easier to diagnose complex autoimmune diseases involving multiple genetic or protein factors. Additionally, companies are launching cutting-edge products and new technologies, which is positively influencing the autoimmune disease diagnosis market outlook. For instance, on 25 March 2024, AbbVie Inc. and Landos Biopharma, Inc. announced a definitive agreement under which AbbVie will acquire Landos, a clinical stage biopharmaceutical company focused on the development of novel and oral therapeutics for patients with autoimmune diseases. The main investigational asset of Landos is NX-13, a first-in-class, oral NLRX1 agonist with a bimodal mechanism of action (MOA).

Rising Focus on Improving Patient Outcomes

The US Food and Drug Administration (FDA) provided clearance for Werfen's Aptiva connective tissue disease (CTD) essential reagent under 510(k) on October 16, 2023. New reagents benefit in speeding up diagnosis and enhancing patient outcomes in difficult-to-diagnose autoimmune disorders. As per the autoimmune disease diagnosis market forecast, rising efforts to enhance early and precise detection for improved patient care are likely to boost demand. Apart from this, early diagnosis of autoimmune disorders enables medical professionals to start treatment quickly while preventing or delaying the onset of diseases, including multiple sclerosis, lupus, and rheumatoid arthritis.

Collaborations and Partnerships among Key Players

On January 10, 2023, ScipherMedicine acquired CrossBridge, a Philadelphia-based data, analytics, and software company, to enhance its data and analytics capabilities. This enables a more granular and real time understanding of patients' treatment pathways. The software as a service (SaaS) value-based care platform aids in lowering healthcare costs while enhancing patient outcomes. Through various collaborations, companies combine their expertise in immunology, molecular biology, and bioinformatics, which supports the autoimmune disease diagnosis market growth. A large number of pharmaceutical companies are collaborating with diagnostic companies to provide companion diagnostics tests that are intended to determine which patients will benefit the most from particular treatments. For instance, in total 2,399,600 of the 15 key diagnostic tests were performed during April 2025. This is an increase of 70,600 (3.0%) from April 2024, which is 8.2% when adjusted for working days. These diagnostics aid in matching patients with the best biologic therapy for autoimmune illnesses, enhancing results while decreasing treatment selection trial and error. These partnerships also involve the co-development of treatments and diagnostic tools. For instance, pharmaceutical companies might work with diagnostics firms to create tests that monitor treatment efficacy, helping doctors adjust therapies in real time to improve patient outcomes.
