Egg test kit is an on-site rapid screening tool for the hen breeding and egg processing industry, specifically developed to identify the potential risk of antibiotic residue in eggs. Unlike common test kits, our egg testing kit places greater emphasis on sensitivity stability, strip storage adaptability and operational reliability during the research and development process. The aim is to help enterprises quickly and accurately assess egg quality without relying on professional laboratories and large-scale instruments. Egg testing kit adopts the principle of immunochromatography reaction. Through the binding and color development of specific antibodies with the target substances to be inspected, the result is easy to read by the naked eye. This enables the detection process from sampling, sample addition to reading to be completed within minutes, greatly improving the detection efficiency. To adapt to the temperature and humidity changes in the environment of the breeding farm, egg test kit is designed with sealed packaging, which can be stored and transported at normal temperature, lowering the usage threshold. Meanwhile, the egg test kits, diluents and supporting tools have all been standardized and configured. Users do not need to have a professional background or experimental foundation to master the detection steps.
