As an important part of the daily diet, the safety and quality of poultry eggs are directly related to the health of consumers. In recent years, with the widespread use of antibiotics in the breeding industry, there may be drug residues in poultry eggs. Among them, quinolones are frequently applied due to their highly effective antibacterial effects, but excessive residues may endanger human health. Therefore, it is essential to quickly and accurately detect quinolones in poultry eggs. The Quinolones Colloidal Gold Rapid Detection Card in poultry eggs is a practical tool to meet this demand.

So, what exactly is the Quinolones Colloidal Gold Rapid Detection Card in poultry eggs? In short, it is a rapid detection product based on immunochromatography technology. The core principle is to use colloidal gold-labeled quinolone antibodies to form a color-developing strip on the test strip through antigen-antibody specific binding reaction, so as to realize qualitative or semi-quantitative detection of quinolone residues in poultry egg samples.

During the specific detection process, the processed poultry egg sample (such as the egg liquid after homogenization) is dripped into the detection card and sample hole, and the sample will flow along the test strip. If the sample contains quinolones (antigens), it will bind to the antibody labeled with colloidal gold, preventing the antibody from binding to the detection line on the test strip (coated with a quinolone-carrier protein conjugate). At this time, the detection line does not show color; if there is no residue in the sample, the antibody binds to the detection line, and the detection line shows color, so as to quickly determine whether there is any residue.

Compared with traditional detection methods (such as high-performance liquid chromatography, mass spectrometry, etc.), the colloidal gold rapid detection card has significant advantages: first, the detection speed is fast, usually results can be obtained within 30 minutes, to meet the needs of on-site rapid screening; second, it is easy to operate, without professional equipment and complex pretreatment, and can be used by ordinary personnel after simple training; third, it is low cost and suitable for large-scale and normalized detection; fourth, it has high sensitivity and can detect very low concentrations of residues (such as ng/mL level) to ensure detection accuracy.

This test card is widely used in the raw material acceptance, processing process monitoring of poultry egg production enterprises, market supervision and sampling inspection in the circulation link, and food safety risk monitoring of government departments. It helps to detect unqualified eggs in a timely manner, control food safety from the source, and ensure consumers' "safety on the tip of the tongue". It can be said that the quinolone colloidal gold rapid test card in poultry eggs is an important part of the quality and safety system of poultry eggs, and is a right-hand assistant to achieve rapid screening and improve supervision efficiency.
