Jiuhe develops and manufactures in vitro diagnostic products for international B2B customers seeking dependable supply, flexible customization, and professional product support. The Covid Influenza Test Kit is positioned for respiratory testing workflows where COVID-19 and influenza screening may be required within the same testing program. Manufacturing processes emphasize controlled assembly, component inspection, packaging consistency, and batch-level quality management. For OEM and private-label projects, Jiuhe can coordinate packaging specifications, labeling requirements, product configurations, and shipment schedules according to the customer's market requirements. A typical seasonal program may involve thousands of tests distributed through clinics, pharmacies, laboratories, or healthcare suppliers. The Covid Influenza Test Kit can therefore serve both recurring procurement programs and seasonal demand planning. Jiuhe also supports international customers with communication throughout product development, production, quality review, and order fulfillment.
