What is the furan quadruple card colloidal gold rapid detection card?

2025-08-18

Furan quadruple card colloidal gold rapid detection card is a rapid detection product developed based on colloidal gold immunochromatography technology, which is mainly used for the simultaneous detection of multiple furan residues in food. In the field of food safety testing, furan drugs (such as furazolidone, furazolidone, furacillin, furantoin, etc.) have been widely used as antimicrobial agents, but some metabolites are carcinogenic and teratogenic, which pose a potential threat to human health. Therefore, rapid screening of furan residues in food is crucial.

The core principle of this detection card is to use the specific antibody labeled with colloidal gold to bind to the residual furan drug metabolites in the sample, and form a color-developing strip on the test strip through the antigen-antibody immune reaction, so as to achieve qualitative or semi-quantitative detection of the target substance. The operation process is very simple, just drop the sample (such as meat, aquatic products, dairy products, etc.) extract into the detection card and sample hole, and wait 10-15 minutes to observe the results: if both the detection line and the control line are colored, it indicates that the sample is not detected or the amount of detection is lower than the detection limit; only the control line is positive; if the control line does not color, the detection is invalid.

Compared with traditional detection methods (such as high-performance liquid chromatography, mass spectrometry, etc.), the furan quadruple card colloidal gold rapid detection card has significant advantages: first, the detection speed is fast, without the need for complex instruments and professional operations, and the detection can be completed within 15 minutes; second, it is high-throughput, which can simultaneously detect four kinds of furan residues, reducing the time and cost of multiple inspections; third, it has high sensitivity and can accurately identify low-concentration residues; fourth, it is portable and suitable for on-site rapid screening. It is widely used in food processing plants, catering enterprises, market supervision departments and other scenarios.

With the increase of food safety supervision and the improvement of rapid detection needs, the furan quadruple card colloidal gold rapid detection card has become an important tool for the screening of furan drug residues in food due to its high efficiency, accuracy and convenience.
