  • Publication number: 20240344108
    Abstract: A galactose rapid quantitative detection system utilizing a test strip containing a concentration of galactose dehydrogenase as the enzyme and a concentration of trehalose as the stabilizer. The system includes a galactose solution composition including a galactose, a buffer and an antioxidant; a test strip, including an enzyme, and a stabilizer; and a meter. The meter includes a power supply unit for providing a signal; a connector for receiving the signal transmitting the signal to the test strip, the signal reacting with the electrochemical information, and the connector transmits the response signal to the meter; a calculation unit for calculating the response signal; an A/D convertor for receiving the response signal from the calculation unit, transforming the response signal into a digital reaction signal; a processor for processing the digital reaction signal; a display for displaying the digital reaction signal; and a digital terminal for receiving the digital reaction signal.
