Point-of-care testing (POCT) for infectious disease encompasses rapid diagnostic assays performed at or near the patient, delivering actionable results within minutes and enabling immediate clinical or public-health decisions. In an era when antimicrobial resistance, pandemic threats, and budget-conscious healthcare intersect, POCT has shifted from convenience to strategic necessity. The Point of Care Testing for Infectious Disease market size is valued at USD 11.2 billion in 2025 and is forecast to reach USD 21.4 billion by 2033, translating to a 7.8% CAGR during 2026-2033. This robust growth outlook is anchored in decentralized care models, widening reimbursement for CLIA-waived tests, and post-COVID infrastructure that embeds rapid diagnostics in pharmacies, workplaces, and low-resource settings. Search-term momentum around “market forecast,” “industry expansion,” and “near-patient screening” reflects board-level prioritization of POCT as a pillar of resilient health systems.
