On the basis of diagnosis, the market is segmented into blood tests, laboratory tests, and others. The Laboratory Tests segment dominated the market with a share of 49.4% in 2025, driven by the central role of molecular diagnostics (PCR) and centralized laboratory confirmation in diagnosing arenavirus infections and guiding treatment decisions. Reference and regional labs perform confirmatory testing, viral load monitoring, and sequencing services that are critical for clinical management and surveillance. Health systems rely on laboratory infrastructure to differentiate arenaviruses from other febrile illnesses and to identify co-infections that affect therapeutic strategy. Investment in centralized diagnostic capacity by governments and international partners during outbreak responses sustains the laboratory tests segment. Laboratory confirmations are often required for reporting, case management, and eligibility for certain treatment programs or clinical trials, which further anchors demand. Quality control, accreditation, and cross-border sample referral networks also concentrate diagnostic spend in laboratory testing.

The Blood Tests segment (rapid point-of-care antigen and serology tests) is expected to be the fastest growing with a CAGR of 24.0% from 2026 to 2033, as technological advances produce faster, cheaper, and more accurate bedside diagnostics that enable immediate triage and early treatment initiation. For instance, validated rapid antigen kits allow clinicians in peripheral clinics to make treatment decisions within hours rather than days, improving outcomes. The expansion of decentralized testing, greater investment in point-of-care platforms, and integration of rapid tests into community surveillance programs drive adoption. Donor funding aimed at outbreak containment also prioritizes deployable blood-based rapid diagnostics, accelerating procurement. As sensitivity and specificity of point-of-care tests improve, clinicians will increasingly rely on them to initiate antiviral therapy earlier, favoring market growth in this subsegment.

• By End-Users

On the basis of end-users, the market is segmented into clinic, hospital, and others. The Hospital end-user segment dominated the market with a revenue share of 58.7% in 2025, reflecting that severe arenavirus cases require inpatient management, intensive supportive care, and parenteral therapy that are only available in hospital settings. Hospitals account for the bulk of high-value purchases (IV solutions, monitoring equipment, ICU beds) and are central to clinical trials and specialist care pathways for hemorrhagic presentations. Procurement contracts, government reimbursement schemes, and emergency stockpiles further channel major spending through hospitals. Referral systems in endemic regions concentrate complicated cases at tertiary hospitals, sustaining high volumes of hospital-based treatment. In addition, hospitals remain key hubs for training, protocol development, and stewardship programs that standardize use of antivirals and supportive therapies.
