The COVID-19 Antigen Test Cassette for nasal swab samples is a lateral flow immunoassay designed for rapid in vitro detection of SARS-CoV-2 nucleocapsid antigen. Each cassette contains a nitrocellulose membrane strip with immobilized antibodies and a colloidal gold-conjugated antibody pad, delivering results in 15 to 20 minutes. Packaging options include 1, 5, or 25 units per box, with individual foil pouches to maintain stability during transit and storage.
The test device uses a plastic casing with a latex-free conjugate pad and a nitrocellulose membrane engineered for consistent capillary flow. The detection mechanism relies on monoclonal antibodies specific to the nucleocapsid protein, with a sensitivity range typical for antigen tests in this category: approximately 85% to 95% for symptomatic samples. The device is not intended for quantitative analysis and does not require lab equipment, making it suitable for decentralized testing environments.
This product is commonly purchased by international distributors, public health agencies, and private clinics seeking point-of-care diagnostic tools. Buyers typically source bulk quantities for distribution across regions with limited laboratory infrastructure. The cassette meets CE and FDA Emergency Use Authorization standards. Trade terms are usually FOB Hangzhou, with lead times confirmed upon order. Packaging is standardized but can be customized for private labeling upon direct request.

Before ordering, verify the test's current FDA EUA status and CE conformity declaration. Confirm that the batch number matches the supplier's latest certificate of analysis. Request a sample for internal validation using clinical specimens, especially if importing into markets with strict diagnostic regulations such as the EU or Canada. Do not rely on marketing claims alone.
Confirm the Incoterms, typically FOB Hangzhou, and whether the supplier handles export documentation. Lead time is usually 7 to 14 days after payment, but this varies with order size and customs clearance. Packaging is in foil-sealed boxes, but bulk cartons may require palletization. Payment terms are commonly T/T in advance; letters of credit are rarely accepted.
Inspect shipments for foil pouch integrity, temperature exposure indicators, and expiration dates. Each box should include a lot number and manufacturing date. Request a certificate of conformity and a test report for each batch. Retain samples for at least six months in case of regulatory audits. Quality checks should include visual inspection for leaks and a small validation run using positive controls.
