Calcium dobesilate is used as a commonly used drug for microvascular protection and treatment, and fensulfate is used as a commonly used drug for hemostasis. These drugs are all strong reducing agents. When patients taking these drugs measure plasma uric acid levels, these reducing drugs will H produced by the decomposition of uric acid by uricase 2 o 2 direct reaction, consumes H 2 o 2 Cause serious negative deviation of uric acid value, resulting in misjudgment of doctors in diagnosis and treatment

Abstract
The invention relates to a uric acid kit for rapidly and simply eliminating drug interference of calcium dobesilate and etamsylate in serum. The uric acid kit is characterized by comprising a reagentR1 and a reagent R2, wherein the reagent R1 comprises a buffer solution, creatinase, creatine oxidase, ascorbic acid oxidase, peroxidase or catalase, serum albumin, a nonionic surfactant, a preservative, a Trinder's reactant A and laccase or metallate; and the reagent R2 comprises a buffer solution, serum albumin, creatininase, a preservative and a Trinder's reactant B. According to the invention,the defect that creatinine determination is inaccurate due to negative deviation caused by the calcium dobesilate and the etamsylate contained in serum samples when creatinine is determined by clinical examination in various hospitals at present is overcome, and the uric acid kit is suitable for detection of serum creatinine by a full-automatic biochemical analyzer.
Description
[0001] This case is a divisional application, specifically the application number: 2020108215098, and the title is: A uric acid kit and its preparation method that can eliminate the interference of calcium dobesilate and phensulfonate in serum, and the application date is: 2020.08.15 divisional application. technical field [0002] The invention belongs to the technical field of medical testing, and relates to a uric acid test kit for quickly and simply eliminating the interference of calcium dobesilate and ethanolamine in serum. Background technique [0003] Uric acid (Uric Acid, UA) is the final product of the metabolism of purine compounds in the body, which is weakly acidic. Uric acid can come from the body or from the catabolism of purines in food. In the body, uric acid is mainly produced in the liver, a small part can be excreted through the liver with bile, and most of the rest are excreted from the kidneys. The solubility of uric acid is small, so it is easy to pr...
