The global protein biomarker immunoassay market size was valued at USD 6.8 billion in 2025 and is projected to grow from USD 7.2 billion in 2026 to USD 11.7 billion by 2033, at a CAGR of 7.1% from 2026 to 2033. North America dominated the market, accounting for the largest revenue share of 37.3% in 2025. Market growth is primarily driven by the growing adoption of blood-based protein biomarker testing for early disease detection, patient stratification, treatment monitoring, and assessment of disease progression across multiple clinical applications.
Blood-based immunoassays are increasingly preferred owing to their minimally invasive nature, established clinical laboratory workflows, and ability to measure disease-associated proteins from serum, plasma, and whole-blood samples.
