Buy & Import COVID-19 Antigen Test Cassette(saliva) from Hangzhou Testsea Biotechnology Co., Ltd. - Wholesale Supply

The saliva-based COVID-19 Antigen Test Cassette is a lateral flow immunoassay designed to detect SARS-CoV-2 nucleocapsid antigen directly from unprocessed saliva samples. Results are available within 15 to 20 minutes using a simple dip-and-read method. The cassette integrates a synthetic polyester pad for sample absorption, a nitrocellulose membrane for antigen capture, and monoclonal antibody conjugates in a plastic ABS/PS housing.

The device operates without centrifugation or sample pretreatment, making it suitable for non-laboratory settings. The detection chemistry relies on gold nanoparticle-labeled antibodies binding to the nucleocapsid protein. Packaging is in individual foil pouches, with 1, 5, or 20 units per box. The product requires storage between 2°C and 30°C and is not freeze-tolerant, which affects logistics planning in colder climates.

This product is primarily purchased by border control agencies, school health programs, and private clinics seeking non-invasive testing options. Buyers often require bulk quantities for mass screening operations. The cassette meets CE and FDA Emergency Use Authorization standards. Trade terms are typically FOB Hangzhou, with lead times confirmed upon order. Custom labeling and packaging are available upon direct negotiation.

Frequently Asked Questions About COVID-19 Antigen Test Cassette(saliva) from Hangzhou Testsea Biotechnology Co., Ltd.
Thick or mucosal saliva can slow capillary flow and cause false negatives. Buyers should instruct users to collect mid-stream saliva and avoid eating, drinking, or smoking for 30 minutes before sampling. A dilution buffer may be required for viscous samples; confirm its inclusion with the supplier.

Sourcing COVID-19 Antigen Test Cassette(saliva) from Hangzhou Testsea Biotechnology Co., Ltd. - China Import Guide

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 saliva 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.
