The global antinuclear antibody test market size was estimated at USD 1.76 billion in 2024 and is projected to reach USD 5.47 billion by 2033, growing at a CAGR of 13.49% from 2025 to 2033. The market growth is accelerated by advancements in antinuclear antibody test (ANA) diagnostics, as it shifts toward standardization and high-throughput autoimmune testing.
The industry is increasingly adopting AI-enabled immunofluorescence platforms that enhance accuracy, consistency, and workflow efficiency.
For instance, in August 2025, Journal of Clinical Medicine demonstrated the value of AI-assisted ANA IIFT, showing good concordance with classical visual interpretation and significantly improving reproducibility in pattern recognition, especially at clinically relevant cut-offs. These findings reinforce AI's emerging role in minimizing observer variability and supporting reliable ANA screening. In parallel, digital IFA imaging solutions are reshaping routine diagnostics.
For instance, in January 2022, ZEUS Scientific, Inc. launched the dIFine platform with an integrated HEp-2 Pattern Atlas, providing automated slide scanning, intelligent pattern recognition, and side-by-side reference image comparison to elevate standardization and operator. AI-driven interpretation, automated digital microscopy, and improved pattern-classification tools are all improving ANA diagnostics, allowing laboratories to meet rising autoimmune disease testing demand with greater precision and operational efficiency.
