Problems solved by technology

[0003] At present, the urinalysis quality control solution on the market needs to use surfactants to stabilize the system, but in this system, the activity of protein substances in it will be reduced, the expression will be weakened, and the sensitivity will be reduced;
[0004] Moreover, due to the use of surfactants for adjustment, the reaction expression of substances in the existing quality control liquid system is reduced, so in order to enhance the reaction effect of the product, it is necessary to increase the amount of ingredients, resulting in increased costs
[0005] In addition, because the existing quality control solution uses surfactants to stabilize the system, after long-term storage, some organic components that are difficult to dissolve in water are prone to isomerization, and protein substances are easily denatured, which is not conducive to long-term storage.

Abstract

The embodiment of the invention discloses a surfactant-free urine analysis quality control liquid. The surfactant-free urine analysis quality control liquid comprises 5-50 mmol / L of a buffer solution,0.1-1 g / L of hydrolase, 50-500 mg / L of BSA, 0.1-1 g / L of bovine hemoglobin, 20-200 mg / L of sodium nitrite, 50-500 mg / L of calcium ions, 20-200 mg / L of a bilirubin substitute, 0.1-1 g / L of a urogen substitute, 0.1-1 g / L of ketone substitute, 50-500 mg / L of creatinine and 1-10g / L of sugar. The surfactant-free urine analysis quality control liquid disclosed by the embodiment of the invention does not need a surfactant or a protein protective agent, so that the real-time stability is improved, the toxicity is lower, the sensitivity is higher, and the detection result is more accurate; moreover, the production cost is lower, and the storage time is longer; and the surfactant-free urine analysis quality control liquid provided by the embodiment of the invention is a greener, more environment-friendly and more excellent urine analysis quality control liquid solution.

Description

technical field [0001] The invention relates to the technical field of urine analysis and detection quality control, in particular to a urine analysis quality control solution without surfactant. Background technique [0002] In today's society, people pay more and more attention to the field of physical health. Among them, urinalysis is used as a routine physical examination method to detect kidney and other diseases, and the quality control of urinalysis is even more important. [0003] At present, the urinalysis quality control solution on the market needs to use surfactants to stabilize the system, but in this system, the activity of protein substances in it will be reduced, the expression will be weakened, and the sensitivity will be reduced; [0004] Moreover, due to the use of surfactants for adjustment, the reaction expressivity of substances in the existing quality control liquid system is reduced. Therefore, in order to enhance the reaction effect of the product, i...
