The Point-of-Care Testing (POCT) Devices segmentation by application reflects the clinical drivers that allocate revenue across the market. Infectious disease testing, encompassing rapid antigen and molecular assays for pathogens such as SARS‑CoV‑2 and influenza, commands the largest share at roughly 30 % of total POCT sales, propelled by urgent demand for decentralized diagnostics. Cardiology applications—including troponin, BNP, and lipid panels—represent about 20 % of the market, supported by hospitals’ need for immediate risk stratification in acute care settings. Diabetes management devices, primarily glucose and HbA1c meters, account for 25 % of the market, sustained by chronic disease prevalence and reimbursement policies favoring home monitoring. Clinical chemistry panels, which cover electrolytes, renal function, and liver enzymes, contribute 15 % as laboratories adopt portable analyzers to shorten turnaround times. Finally, drug monitoring (e.g., therapeutic drug monitoring for antibiotics and anticoagulants) holds a 10 % share, driven by antimicrobial stewardship programs and personalized dosing protocols. Together, these application segments define the overall market size and growth trajectory.
