[0001] The invention relates to an in vitro detection reagent for clinical diagnosis, in particular to a preparation method of a p-hydroxyphenylalanine urine detection reagent. Background technique

[0002] Cancer mortality ranks first among all diseases and is the number one killer of human health. It has become a major cause of death that threatens human life and health. According to statistics, the number of cancer patients will double every 25 years. Not only that, the number of deaths from cancer is also rising rapidly around the world, and this number may increase to 13.2 million in 2030. Early detection is the key to the treatment of tumors. The development of tumors is divided into five stages: benign, tumor cell initiation, early tumor, mid-tumor, and late stage. The frightening thing about cancer is that the first three stages cannot be detected by imaging. Even in the middle stage of the tumor, only very professional doctors can detect it with adv...
