U.S. Lateral Flow Assay Market Size Worth USD 5.39 Billion by 2034 | CAGR: 6.2%

The U.S. lateral flow assay market size is expected to reach USD 5.39 billion by 2034, according to a new study by Polaris Market Research. The report “U.S. Lateral Flow Assay Market Size, Share, Trends, Industry Analysis Report By Product (Kits & Reagents, Lateral Flow Readers, Benchtop Readers), By Application, By Technique, By End Use – Market Forecast, 2025–2034” gives a detailed insight into current market dynamics and provides analysis on future market growth.

A lateral flow assay is a simple, paper-based diagnostic device used to detect the presence of a target substance, such as proteins, hormones, or pathogens, in a liquid sample.

The lateral flow assay application is expanding in noninfectious and nonclinical settings. While lateral flow assays were originally designed for infectious disease testing, they are now being used in a much wider range of applications. In healthcare, tests are being developed for conditions such as cancer, heart disease, and even neurological disorders. These tests can detect biomarkers related to disease risk or progression, helping doctors monitor patients more easily. Beyond medicine, LFAs are also used in veterinary care, food safety, and environmental monitoring. For example, they detect allergens in food or harmful bacteria in water. In agriculture, they help monitor animal health quickly on-site. This broad range of uses means that the demand for lateral flow tests is not limited to hospitals and clinics. As new applications are developed, particularly in industries that need fast results without lab access, lateral flow technology becomes even more important. This expansion into nontraditional settings drives the U.S. lateral flow assay market expansion.

The use of smartphones and digital readers is changing how lateral flow assays are interpreted and recorded. Instead of relying solely on human eyes to judge a faint line, digital readers and apps help provide more accurate and consistent results. Many of these tools read the test strip, interpret the result, and even store or transmit data directly to healthcare providers. This digital integration is particularly helpful in remote monitoring, telemedicine, and managing chronic conditions. For example, a patient can test at home and send the result to their doctor without needing to visit a clinic. These digital features also reduce the chances of misreading the result and improve data collection for public health tracking. As digital health becomes more common in the U.S., the ability to pair tests with smart technology makes lateral flow assays even more appealing, especially for patients who want fast answers with professional follow-up options.
