The Vet Immunoassay Analyzer segmentation by application reveals a market driven by four clinically distinct workflows. Routine screening dominates, accounting for 42 % of 2023 unit placements, as clinics outsource reference-lab workloads to in-house systems for wellness panels and pre-surgical screens. Disease diagnostics follows at 31 %, propelled by rising endocrine, infectious, and neoplastic cases where immunoassay specificity outperforms rapid tests. The therapeutic monitoring niche (18 %) is expanding fastest, supported by specialty hospitals titrating insulin, thyroxine, or phenobarbital via same-day chemiluminescent assays. Finally, research & surveillance (9 %) is concentrated in academic and pharmaceutical settings validating novel biomarkers or tracking herd health, generating lower volumes but commanding premium pricing.
