Without consistent coverage, laboratories hesitate to invest in high-throughput multiplex platforms, constraining penetration outside tertiary centers. Policymakers are beginning to recognize the cost-avoidance potential of early diagnosis, yet budget realignments will roll out gradually, tempering near-term market acceleration.

Segment Analysis

By Disease Type: Systemic Testing Dominates While Point Solutions Accelerate

Systemic autoimmune diseases generated 62.92% revenue in 2024, reflecting the multi-organ nature of conditions such as rheumatoid arthritis, systemic lupus erythematosus, and multiple sclerosis that require broad antibody panels for differential diagnosis. This segment alone captured the largest slice of the autoimmune disease diagnostics market, as clinicians deploy multiparametric profiles to parse overlapping presentations across organ systems. Localized autoimmune diseases, though smaller in volume, are scaling at a 9.6% CAGR thanks to portable devices that bring thyroid, celiac, and type 1 diabetes testing closer to primary-care clinics. The autoimmune disease diagnostics market size tied to systemic evaluations is projected to climb steadily as treatment guidelines embed routine disease-activity monitoring to tailor biologic therapy. Simultaneously, fecal calprotectin assays refine inflammatory bowel disease work-ups, disentangling autoimmune etiology from functional disorders and widening adoption among gastroenterologist.

Second-generation T-cell assays enhance systemic lupus detection by identifying cellular immunity markers absent in classic serology, revealing previously overlooked sub-phenotypes. In multiple sclerosis, neurofilament light chain quantification integrates with autoantibody panels to improve prognostication, sharpening demand for multi-analyte workflows. Growth on the localized front is tied to at-home finger-stick kits that detect anti-tTG antibodies, empowering earlier celiac intervention and enlarging the consumer-initiated testing cohort. Overall, systemic testing retains scale advantages, but localized disease panels represent an agile growth niche for innovators targeting primary-care and retail health settings.
