Kit for qualitatively detecting tyrosine metabolites in human urine

Abstract

The invention discloses a kit for qualitatively detecting tyrosine metabolites in human urine. The kit is formed by mixing the following reagents: 0.2-0.5g / mL of mercuric chloride solution, 0.5-1.0g / mL of mercuric nitrate solution, and 0.05-0.1g / mL of ferric nitrate solution, the volume ratio of the mercuric chloride solution to the mercuric nitrate solution to the ferric nitrate solution is 1 to (0.5-2) to (0.5-1.5). The kit disclosed by the invention has the features that the operation method is simple; a special apparatus is not needed; the urine of a patient is adopted for detection, so that the detection is noninvasive, and easy to implement; the result can be instantly obtained; the detection expense is lower than that of the similar method; the kit is suitable for large-scale population screening and therapeutic effect monitoring of cancerous person, and further suitable for the primary hospital.

Description

technical field

[0001] The invention relates to a kit for qualitatively detecting tyrosine metabolites in human urine. Background technique

[0002] The key to early detection of cancer is regular screening. Among the many tumor markers, protein, hormone or other markers cannot be used as screening markers because they cannot be expressed in a wide enough range of tumors, and most of them are destructive tests. Complex and expensive, it is not suitable for large-scale population screening; detecting tumors through urine avoids the link of blood drawing, which is easy to cause infection, and there are many methods at home and abroad, such as: high performance liquid chromatography (HPLC) Polyamine, ELISA method for determination of urinary ferritin, determination of tyrosine and its metabolites in urine and protein chip detection of tumor markers, etc. Each method has advantages and disadvantages. For example, the HPLC method for the determination of urinary polyamines has ...
