Sample diluent applicable to peripheral blood detection

Abstract

The invention discloses a sample diluent applicable to peripheral blood detection. The sample diluent per 1,000ml is prepared from the ingredients: 20.5g of glucose, 8.5g of sodium chloride, 2g of bovine serum albumin, 0.55g of citric acid, 0.4ml of Proclin 300 and 2ml of gentamicin sulfate. The sample diluent is readily available in required raw materials, low in price and free of blood serum ingredient, the risk of infecting some special viruses is avoided, the osmotic pressure of solutions inside and outside cells is balanced by various ions, and the preservation effect is remarkable. The optimized sample diluent is high in applicability, wide in range of application and superior in oxidation resistance and can exert a protecting action during the transportation and preservation of peripheral blood diluted samples.

Description

technical field [0001] The invention relates to the field of medical reagents, in particular to a sample diluent suitable for peripheral blood detection. Background technique [0002] The human body circulates through the heart and arteries, veins, and capillaries throughout the body. There are two main ways for people to draw blood tests in hospitals, i.e. venous blood and peripheral blood. The venous blood is generally drawn from the cubital vein, which is punctured with a syringe. The amount of blood drawn is related to the number of test items. The amount of blood drawn is generally a few milliliters. Immunological tests and most special tests. Peripheral blood usually uses earlobe blood and finger blood, which is convenient for sampling and requires a small amount of blood. It is often used in simple and fast tests such as blood routine examination, blood type identification, and rapid blood sugar detection. Due to the rapid development of modern measurement technolo...

Problems solved by technology

[0006] In order to solve the problems of bacterial contamination and blood cell damage (hemolysis) in the storage and transportation of peripheral blood samples, the present invention provides a sample diluent suitable for peripheral blood testing, which prevents bacterial growth of samples by adding bacteriostatic agents. Deterioration; at the same time, blood cell nutrients are added to improve the viability of blood cells; crystal osmotic pressure and colloid osmotic pressure are also adjusted to ensure the activity of antibodies and enzymes in the sample, maintain the stability and integrity of blood cells, and meet the needs of clinical testing.
