The U.S. lateral flow assay market was valued at USD 2.97 billion in 2024 and is projected to grow at a compound annual growth rate (CAGR) of 6.2% during the forecast period from 2025 to 2034. By the end of 2034, the market is anticipated to reach approximately USD 5.39 billion, fueled by advancements in point-of-care diagnostics, increasing prevalence of chronic and infectious diseases, and growing demand for rapid, reliable, and user-friendly diagnostic tools.

Market Overview

Lateral flow assays are paper-based devices used to detect the presence (or absence) of a target analyte in liquid samples without the need for specialized laboratory equipment. Widely recognized for their simplicity, speed, and affordability, these assays are a cornerstone of point-of-care (POC) and home diagnostics in the United States.

Initially popularized through pregnancy tests and infectious disease diagnostics, lateral flow technology has expanded its application into cardiac markers, cancer screening, veterinary testing, food safety, and drug abuse detection. With the U.S. healthcare sector increasingly focused on decentralization and early intervention, LFA-based platforms are becoming an essential diagnostic modality.

Key Market Drivers

🔹 1. Rising Demand for Point-of-Care Testing (POCT)

Lateral flow assays are integral to POCT settings due to their ease of use, fast results, and minimal need for technical training. The shift toward decentralized healthcare, including telemedicine, home-based care, and urgent care clinics, is significantly boosting the adoption of LFAs in the U.S. market.

🔹 2. High Burden of Chronic and Infectious Diseases

The United States continues to witness high prevalence rates of chronic diseases such as diabetes, cardiovascular disorders, and infectious diseases like influenza, COVID-19, HIV, and STIs. Lateral flow assays play a critical role in early detection, disease monitoring, and surveillance, particularly in time-sensitive or resource-limited situations.

🔹 3. Technological Advancements and Digital Integration

Recent innovations have enhanced the sensitivity, specificity, and multiplexing capabilities of LFAs. Integration with smartphone readers, cloud-based reporting, and AI-enabled analytics is transforming LFAs into data-rich diagnostic tools, offering valuable insights and enabling real-time epidemiological tracking.

🔹 4. Strong Regulatory Support and Emergency Use Authorizations (EUAs)

The U.S. FDA’s proactive stance on approving lateral flow-based devices, especially during public health emergencies, has accelerated product development and market entry. Rapid approvals during the COVID-19 pandemic set a precedent for future fast-track diagnostics.

🔹 5. Growing Preference for Home Diagnostics

The rise in consumer health awareness, coupled with a growing preference for self-testing, has led to increased demand for OTC (over-the-counter) lateral flow kits, particularly for pregnancy, ovulation, glucose monitoring, and infectious disease screening.
