Import Doa Rapid Diagnostic Test Uncut Sheet — Buy in Bulk from Supplier in Canada

The Doa rapid diagnostic test uncut sheet from Ntbio Diagnostics Inc. is a lateral flow immunoassay strip designed for point-of-care detection of specific biomarkers in human serum or urine. Each uncut sheet measures 120 mm in length and 4 mm in width, with a backing of polyethylene terephthalate and a nitrocellulose membrane as the capture substrate. The test lines are printed using gold nanoparticle-conjugated antibodies, and the control line uses a secondary antibody binding system. These dimensions and materials align with standard industry formats for uncut diagnostic strips.

The product is manufactured using validated conjugate chemistry and membrane batch consistency protocols. The nitrocellulose membrane has a flow rate of 100 to 150 µL/min, which is typical for lateral flow devices requiring rapid capillary action. The conjugate pad contains stabilised colloidal gold and blocking agents to reduce non-specific binding, a standard practice in diagnostic strip production. The sheet is designed for use in ambient temperatures between 15°C and 30°C and has a shelf life of 24 months when stored dry.

This uncut sheet is primarily purchased by diagnostic kit assemblers, laboratory reagent manufacturers, and OEM partners who integrate it into automated or manual test cassettes. Buyers typically order in multiples of 5,000 strips per batch for downstream lamination and packaging. The product is shipped in sealed foil pouches with desiccant, and trade terms include FOB Vancouver and EXW from Richmond, BC. Lead time for standard orders is 14 to 21 days after payment confirmation.
