Market Growth Factors

The increasing need for rapid and accurate diagnostics is a primary growth driver. Development in isothermal nucleic acid amplification for detecting COVID-19, along with a growing geriatric population projected to reach 1.6 billion by 2050, fuels demand. In 2023, the US faced nearly 2 million new cancer cases, increasing the need for efficient diagnostic and treatment options. Diseases like tuberculosis, West Nile virus, Zika, and chikungunya further underscore the need for rapid and sensitive diagnostic tools such as INAAT.

Advancements in personalized medicine and molecular diagnostics stimulate market growth. INAAT enables fast and cost-effective detection of genetic mutations and pathogens supporting targeted therapies. Innovations such as the Panther Trax system by Hologic, Inc., represent the commitment to automating high-volume testing, improving efficiency and accuracy in the US and globally. Increasing molecular diagnostics adoption across healthcare sectors is reinforcing INAAT's role in patient care.

Technological innovations and adoption of portable devices enhance INAAT applications in field diagnostics and remote settings. Techniques such as Loop-mediated Isothermal Amplification (LAMP) and Helicase-Dependent Amplification (HDA) improve sensitivity and specificity. The integration of INAAT with portable, user-friendly devices expands its use in resource-poor settings, military, and travel health screenings. The growing global cancer burden, with 19.3 million new cases in 2020, amplifies the urgency for rapid and precise diagnostics that INAAT can provide.
