Abstract

This invention discloses a test agent box to measure the contents of copper, iron and zinc in blood serum and provides the process method of the agent box. The agent box in this invention dissociates the protein with copper, iron and zinc in blood serum in the buffer liquid system with the surface activity agent, which is compound with the pyridylazo organic compound to make color. The color complex compound has the longest wavelength at 550-600nm.

Description

technical field [0001] The invention relates to rapid and sensitive detection kits respectively used for detecting the contents of copper, iron and zinc in blood serum and preparation methods of the respective kits. Background technique [0002] Copper, iron, and zinc are essential trace elements for the human body. [0003] Elevated serum copper is seen in leukemia, Hodgkin's disease, pigmentation, tuberculosis, pernicious anemia, and malignant tumors. Decreased serum copper is seen in infant anemia, infant malnutrition, Menkes curly hair syndrome, hepatolenticular degeneration and so on. There are many methods for measuring serum copper. At present, the preferred clinical method is atomic absorption spectrophotometry, which is adopted by most foreign laboratories. However, this method is expensive and difficult to popularize in clinical laboratories in my country. It is a spectrophotometric method, and the first method of the spectrophotometric method is to use dicyclohex...
