This uncut sheet product is a bulk-format COVID-19 IgG/IgM rapid test using colloidal gold immunochromatographic technology for qualitative antibody detection. Designed for high-volume laboratory and manufacturing use, each sheet supports multiple test configurations across whole blood, serum, and plasma (WB/S/P) sample types. The test principle relies on recombinant SARS-CoV-2 antigen labeled with colloidal gold binding to IgG and IgM antibodies in the sample, with results visualized on nitrocellulose membrane detection lines (G for IgG, M for IgM) and a control line (C) for validity confirmation.
The kit incorporates a nitrocellulose membrane with fixed detection and control lines, alongside latex/colloid conjugate and plastic cassette housing components. Typical lateral flow assays of this type achieve sensitivity and specificity rates above 90% for antibody detection, with color intensity on the test lines correlating to antibody concentration. Industry-standard validation includes cross-reactivity testing against common interfering substances and confirmation of shelf-life stability under controlled storage conditions.
Primary applications include hospital laboratories, public health screening programs, and manufacturing for redistributors requiring CE or FDA-compliant variants. Bulk orders enable cost-effective import for global distribution, with the uncut sheet format allowing customization for regional test assembly. Buyers typically source these for use in clinical diagnostics, workplace testing programs, or epidemiological studies, with trade terms negotiated per shipment volume and destination.

Before ordering, verify the supplier’s GMP certification and confirm whether the uncut sheets meet CE or FDA requirements for your target market. Request batch-specific validation data, including sensitivity and specificity reports, to ensure compliance with local diagnostic regulations. Cross-check the shelf life and storage conditions to avoid receiving expired or degraded stock.
Logistics terms should be clarified upfront, including Incoterms (FOB Shenzhen is typical for this origin), packaging specifications for bulk shipments, and lead times for custom assembly. Air freight may be necessary for temperature-controlled transport, as colloidal gold conjugates can degrade if exposed to extreme heat or cold during transit.
Quality checks should include visual inspection of the uncut sheets for membrane integrity and conjugate consistency, as well as functional testing of a sample batch. Request documentation such as material safety data sheets (MSDS) for the colloidal gold and nitrocellulose components, and confirm the supplier’s ability to provide COAs (Certificates of Analysis) for each shipment.
