As an important source of nutrients in the daily diet, the quality and safety of poultry eggs are directly related to the health of consumers. However, some veterinary drugs such as ciprofloxacin may be used illegally in the process of breeding, resulting in drug residues in poultry eggs and affecting food safety. In order to quickly and accurately detect the residues of ciprofloxacin in poultry eggs, the rapid detection card of ciprofloxacin colloidal gold in poultry eggs came into being.

This detection card is a rapid detection product developed based on colloidal gold immunochromatography technology. It is mainly used for qualitative or semi-quantitative detection of ciprofloxacin residues in poultry eggs (such as eggs, duck eggs, etc.). The core principle is to use the colloidal gold-labeled ciprofloxacin antibody to generate an immune competition reaction with the ciprofloxacin in the sample: when the sample contains ciprofloxacin, it will compete with the ciprofloxacin-carrier protein conjugate coated on the detection card to bind the colloidal gold-labeled antibody. If the concentration of ciprofloxacin in the sample reaches a certain threshold, a color-developing band will appear on the detection line, otherwise it will not develop color. The result can be judged by comparing it with the quality control line.

Compared with traditional detection methods (such as high performance liquid chromatography, mass spectrometry, etc.), this detection card has significant advantages: first, the detection speed is fast, usually 10-15 minutes to produce results, greatly shortening the detection cycle; secondly, the operation is simple, no professional instruments and complex pretreatment are required, and ordinary personnel can get started with simple training; furthermore, the cost is low, making it suitable for large-scale screening; in addition, the sensitivity is high, and the residual concentration of ng level can be detected, which can effectively identify low-dose contaminated samples.

In practical applications, the rapid detection card of ciprofloxacin colloidal gold in poultry eggs is widely used in scenarios such as raw material self-inspection in poultry egg production enterprises, rapid sampling in wholesale markets, and on-site screening by regulatory authorities. Through the test card, unqualified eggs can be found in time, and the risk of veterinary drug residues can be controlled from the source, which provides strong technical support for ensuring the quality and safety of eggs and maintaining consumer health.
