Autoimmune diseases — conditions in which the body’s immune system mistakenly attacks its own tissues — present significant diagnostic challenges due to overlapping symptoms, varied progression, and multiple organ involvement. As a result, advanced diagnostics — including autoantibody assays, multiplex panels, molecular tests, and imaging adjuncts — are increasingly critical for accurate identification, monitoring, and treatment decision-making.

Introduction: The Growing Need for Autoimmune Diagnostics

Autoimmune disorders such as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), Hashimoto’s thyroiditis, type 1 diabetes, and multiple sclerosis are widespread and often under-diagnosed. Estimates suggest tens of millions globally live with one or more autoimmune conditions — for example, in the U.S., approximately 50 million people are affected. Polaris+1

The diagnostic pathway for these disorders typically involves:

• Screening tests (e.g., antinuclear antibody (ANA) tests, anti-dsDNA)
• Confirmatory tests (multiplex autoantibody panels, immunofluorescence, molecular assays)
• Monitoring tests (biomarkers, imaging, functional studies)

The increasing shift toward personalised medicine, early detection, and monitoring of therapeutic efficacy is placing higher expectations on diagnostics players to deliver high accuracy, lower turnaround times, and integrated reporting.

Market Dynamics

Key Drivers

• Increasing prevalence of autoimmune diseases: The rising incidence of disorders such as RA, SLE, type 1 diabetes and MS is creating heightened demand for diagnostics. Polaris+1
• Technological advancements: Innovations such as multiplex immunoassays, next-generation sequencing (NGS), automated immunofluorescence, and point-of-care platforms are enhancing diagnostic sensitivity and speed. Polaris+1
• Growing awareness and early screening campaigns: More healthcare systems are promoting autoimmune screening, especially in populations at risk (e.g., women under 40 for SLE). Polaris+1
• Expansion of diagnostic infrastructure in emerging markets: Countries like China, India, and Brazil are increasing investments in diagnostic labs and healthcare access, offering new growth avenues. Polaris

Restraints

• Cost and complexity of advanced diagnostic assays: Multiplex panels and molecular tests can be expensive and need skilled personnel, limiting adoption in resource-constrained settings.
• Heterogeneity of autoimmune diseases: Overlapping symptoms and a lack of standardisation across tests can lead to misdiagnosis or delayed diagnosis.
• Reimbursement and regulatory hurdles: In many regions, reimbursement for newer diagnostic panels is limited, slowing uptake.

Opportunities

• Point-of-care (POC) diagnostics and decentralised testing: Developing rapid, lower-cost autoimmune diagnostics for primary care and outpatient settings.
• Integration with digital health and AI: Using algorithms to interpret complex autoantibody patterns, predictive analytics for flares, and remote monitoring.
• Emerging market expansion: Leveraging growth in Asia-Pacific and Latin America to deliver cost-effective diagnostics.
• Therapeutic monitoring and companion diagnostics: As biologics and targeted therapies for autoimmune diseases proliferate, the need for diagnostics that track disease activity and treatment response becomes critical.

Segmentation Analysis

By Type

• Systemic Autoimmune Disease Diagnostics (e.g., RA, SLE, ankylosing spondylitis) – historically dominant segment due to higher complexity and need for broad panels. Polaris
