The Covid-19 IgG/IgM Rapid Test Cassette from Span Biotech Ltd. is a colloidal gold immunochromatographic assay designed for the qualitative detection of IgG and IgM antibodies against 2019-nCoV in human serum, plasma, or whole blood. Each kit contains 25 individual test cassettes, with results visible within 10-15 minutes without the need for laboratory instruments. The test employs a nitrocellulose membrane strip with fixed detection lines for IgG (G line) and IgM (M line), alongside a control line (C line) to validate the test.
The assay uses recombinant 2019-nCoV antigens conjugated to colloidal gold, which bind to antibodies in the sample and migrate along the membrane to produce visible bands. Typical lateral flow assays of this type achieve clinical sensitivity of 85-95% and specificity of 95-100% for SARS-CoV-2 antibodies, though exact performance depends on the timing of sample collection relative to infection. Standard storage conditions are 4-30°C with a shelf life of 18 months when unopened, while opened kits should be used immediately to avoid degradation of reagents.
This product is primarily sourced by medical supply importers, clinical laboratories, and public health agencies for point-of-care screening and auxiliary diagnosis. It is particularly valuable in settings where rapid results are critical, such as airports, border crossings, and remote clinics. Buyers should confirm the kit’s certification status for their target market, as regulatory requirements vary by country for in vitro diagnostic devices.

Before placing an order, confirm the kit’s regulatory approvals for your destination country, as requirements for in vitro diagnostics vary widely. Request the supplier’s ISO 13485 certification or equivalent quality management system documentation to ensure compliance with medical device standards. Verify the batch-specific performance data, including sensitivity and specificity, as these metrics can differ between production runs.
Clarify the Incoterms offered by Span Biotech Ltd., as medical diagnostics often ship under DDP (Delivered Duty Paid) or FOB Shenzhen to simplify customs clearance. Confirm lead times, as rapid test kits may be subject to fluctuating demand and supply chain constraints. Payment terms should be negotiated in advance, with consideration for secure methods such as letters of credit or escrow for high-value orders.
Inspect a sample batch upon arrival to validate the kit’s integrity, including the presence of all components and intact packaging. Request the supplier’s internal quality control records and third-party test reports to verify performance claims. Ensure the documentation includes the kit’s lot number, expiration date, and storage instructions to meet local regulatory requirements.
