The Covid 19 Rapid Test Colloidal Gold IgG/IgM from Wincos International Limited is a serological point-of-care diagnostic kit for qualitative detection of SARS-CoV-2 antibodies in human serum, plasma, or whole blood. It employs colloidal gold conjugates with recombinant antigens targeting the nucleocapsid and spike proteins of the virus, delivering results within 10 to 15 minutes. The test uses a lateral flow immunochromatographic format, with components including a nitrocellulose membrane, absorbent pad, and plastic cassette housing.
This assay is standard for epidemiological surveillance and rapid screening in clinical laboratories, hospitals, and border checkpoints. Each kit is individually packaged with a sterile lancet, dropper, and buffer solution to ensure reliable field performance. The test distinguishes between IgG and IgM antibodies, providing insights into the stage of infection, with IgM typically indicating recent exposure and IgG suggesting a later or past infection.
Wincos International Limited supplies these kits for B2B import and export trade, catering to healthcare facilities, emergency response teams, and large-scale testing campaigns. The kits are designed for ease of use, requiring no specialized training, and their compact format allows for easy transport and storage. Buyers should confirm the regulatory compliance of the kits for their intended markets, as certifications such as CE are typically required.

Before placing an order, confirm the regulatory certifications held by Wincos International Limited for the Covid 19 Rapid Test Colloidal Gold IgG/IgM kits. CE certification is typically required for European markets, while other regions may have additional standards. Request documentation to verify compliance with your target market’s requirements to avoid delays during import.
