Abstract

The application discloses a kit for detecting immunoglobulin G in urine, which belongs to the technical field of medical in vitro diagnosis. The kit includes reagent R1 and reagent R2; the reagent R1 includes the following components: Tris base, polyethylene glycol, polyvinylpyrrolidone, sodium chloride, surfactant S9, EDTA-Na 2 and sodium benzoate; the reagent R2 includes the following components: tris base, goat anti-human immunoglobulin G polyclonal antibody, animal serum, sodium benzoate, trehalose, EDTA-Na 2 and Twain. The kit of this application has high sensitivity, wide linear range and good repeatability, and can accurately detect low-value samples; at the same time, the kit of this application also has good stability, and the reagents can be stably stored in 14 samples It eliminates the filtration step before the reagent is used, which simplifies the operation steps and improves the accuracy of the test results.

Description

technical field [0001] The application relates to the technical field of medical in vitro diagnosis, in particular to a kit for detecting immunoglobulin G in urine. Background technique [0002] Immunoglobulin (Ig) refers to a globulin having antibody (Ab) activity or a chemical structure similar to an antibody molecule. Immunoglobulin G is the main immunoglobulin in the blood, most of which exist in the form of monomers, mainly composed of spleen and lymph, and cannot be filtered by glomeruli, so the content in normal human urine is extremely low. [0003] The content of IgG in the urine of patients with primary glomerulonephritis and chronic nephritis is high, and only slightly increased in other types of glomerular diseases; IgM only appears in the urine of patients with chronic nephritis, while in primary glomerulonephritis and occult nephritis patients with very little urine content. Therefore, the type of elevated Ig in urine can be analyzed to help differentiate the...
