Description
technical field [0001] The invention relates to a urine detection reagent for p-hydroxyphenylalanine tyrosine, and also relates to a detection method for monohydric phenolic metabolites in human urine. Background technique [0002] Early screening of cancer is a very important means to reduce cancer morbidity and mortality. Currently common detection methods include various tumor markers, infrared rays, X-rays, etc. Tumor markers need to go to the hospital to draw blood, and special equipment is needed for detection. The same is true for infrared rays and X-rays. The current screening methods all involve various instruments and equipment, which are complicated and costly. The detection of tumor markers in urine has always been a research hotspot in the world, and the use of tumor markers in urine to screen early cancers has been generally recognized by scientific researchers and consumers. [0003] Cancer screening reagents need to have good sensitivity and specificity, b...
