COVID-19 Antigen Rapid Test Kit (TRFIA)
The COVID-19 Antigen Rapid Test Kit from Lumigenex (Suzhou) employs time-resolved immunofluorescence (TRFIA) technology to detect SARS-CoV-2 antigens in patient samples. This immunofluorescent sandwich assay forms complexes between the virus’s N protein and labelled antibodies, which are then visualised under UV light as a red test line on the nitrocellulose membrane. A control line pre-coated with Chicken IgY confirms the test has run correctly, appearing in every valid result.
TRFIA-based tests are known for their high sensitivity and specificity, often exceeding those of colloidal gold assays due to the enhanced signal-to-noise ratio of fluorescent detection. Typical industry standards for TRFIA antigen tests include a detection limit of 50-200 TCID50/ml, with standard storage at 2-30°C and humidity below 80%. The assay’s fluorescent microsphere probes provide stronger signal intensity, enabling detection of lower viral loads in early-stage infections.
This kit is designed for professional use in point-of-care settings and clinical laboratories, offering rapid results within minutes. Importers such as diagnostic labs, hospitals and public health agencies source TRFIA kits for their superior performance in mass screening programs. The product is individually packaged with all reagents and accessories, meeting international quality standards for in vitro diagnostic use.

Sourcing COVID-19 Antigen Rapid Test Kit (TRFIA) from Lumigenex (Suzhou) Co., Ltd - China Import Guide
Prior to ordering, confirm that the TRFIA test kit meets the regulatory requirements of your importing country, such as CE-IVD certification for the European market or local health authority approvals. Request the supplier’s compliance documentation, including ISO 13485 quality management system certificates, to ensure the product adheres to international diagnostic standards.
Discuss logistics arrangements, including Incoterms (e.g., FOB Suzhou or CIF destination), lead times for bulk shipments and packaging specifications. TRFIA kits often require controlled temperature storage during transit, so clarify whether the supplier provides temperature-stable packaging or if cold chain logistics are necessary for your route.
Validate the kit’s performance by requesting batch-specific quality control reports, including sensitivity, specificity and cross-reactivity data. Conduct on-arrival inspections to check for damage to the test cassettes, reagents and fluorescent probes. For large procurement orders, consider independent laboratory validation to confirm the kit’s diagnostic accuracy meets your programme’s requirements.
