Abstract

The invention relates to the technical field of medical inspection, in particular to a general whole blood glucose quality control product for a blood glucose analyzer and a preparation method thereof, wherein the quality control product comprises 4-9 * 10<9> / L of white blood cells, 3.5-5.5 * 10<9> / L of red blood cells, a phosphate buffer solution with concentration of 20-200 mM and pH value of 7.0-7.5, a preservative with the mass concentration of 0.05-0.15%, an antioxidant with the mass concentration of 0.05-0.15%, glucose with the mass concentration of 0.01-0.025%, and glutaraldehyde with the mass concentration of 0.2%-0.6%. The general whole blood glucose quality control product for the blood glucose analyzer can realize quality control for a portable glucometer in a mode using inspection and quarantine qualified animal blood to simulate human blood whole blood, the use effects of human blood state detection glucometer and a blood glucose test strip can be accurately simulated, andthe accuracy and the reliability of blood glucose detection results are improved. The general whole blood glucose quality control product for the blood glucose analyzer is high in universality, and can be used for carrying out quality control on glucometers of different manufacturers and different types.

Description

technical field [0001] The invention relates to the technical field of medical testing, in particular to a universal blood glucose quality control product for blood glucose analyzers and a preparation method thereof. Background technique [0002] Human blood contains a certain concentration of glucose, referred to as "blood sugar". Under normal circumstances, the "blood sugar" of the human body maintains a dynamic balance, fluctuating between 70-140mg / dl (3.9-7.8mmol / ), and the highest does not exceed 180mg / dl (10mmol / l). After eating, the gastrointestinal tract digests and hydrolyzes the ingested carbohydrates and polysaccharides into simple sugars, that is, glucose is absorbed into the blood, causing blood sugar to rise, and with the use and storage of glucose, the blood sugar gradually decreases; when hungry, the original storage The glucose in the body is released into the blood, so the blood sugar rises to maintain a dynamic balance. In clinical medical examination, t...
