The In Vitro Diagnostics Market Size is fundamentally influenced by the Infectious Disease Application Segment, which remains the largest revenue contributor (capturing around 43.52% revenue share in 2024). While the extraordinary, temporary surge in demand created by the COVID-19 pandemic has normalized, the segment's underlying size and stability are driven by persistent global health threats and new technologies.

Key factors sustaining the massive market size in this segment are:

1. Endemic Infectious Diseases: Continuous, high-volume testing is required for prevalent diseases like HIV/AIDS, Hepatitis (B and C), and Tuberculosis (TB). For example, IVD for HIV is essential for diagnosis, viral load monitoring (to assess treatment efficacy), and prevention efforts, creating perpetual demand. The HIV segment alone is anticipated to grow at a noteworthy CAGR.

2. Public Health Initiatives: Major funding from global organizations (e.g., WHO, Global Fund) and government programs in developing regions focuses on procuring affordable, decentralized IVD solutions for infectious disease control, specifically targeting the Point-of-Care (PoC) sector to reach underserved populations.

3. Antimicrobial Resistance (AMR): The fight against AMR mandates the use of rapid diagnostics (mostly Molecular Diagnostics and Microbiology) to quickly and accurately identify pathogens before prescribing antibiotics, thereby driving investment in multiplex testing and pathogen identification panels.

4. Technological Shift in Testing: The move from traditional, low-sensitivity methods to highly accurate, automated molecular diagnostics platforms (PCR, NGS) ensures that even as testing volumes for a single pathogen fluctuate, the revenue per test increases due to the higher value of the technology used.

Despite the decline in pandemic-era revenues, the large, non-cyclical demand base for managing high-burden global infections ensures that the Infectious Disease segment remains the largest and most critical component of the overall IVD market size.
