At the same time, with the prolongation of storage time and the change of temperature, MCV will also change, which will cause errors in the measurement of MCV.
error in clinical diagnosis
[0005] In the existing blood diluents, generally by adding a stabilizer to the diluent formula, the pre-diluted blood specimens can be further improved after a period of time, and the white blood cell classification characteristics and MCV stability will not change. After a certain period of time, the effect is not good, and at the same time, the diluent used for the existing hematology analyzer cannot guarantee the classification and stability of MCV and white blood cells at the same time

Embodiment Construction
[0015] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0016] The invention provides a diluent for a blood analyzer, each liter of blood sample diluent contains:
[0017] Sodium chloride 5-10g, sodium sulfate 8-12g, ethylenediaminetetraacetate (EDTA-M) 0.1-0.3g, potassium chloride 0.2-0.8g, imidazole 1-3g, purine compounds 0.1-5g, Polyoxyethylene alkyl ether 0.01%~0.1% (weight), preservative 1~3g;
[0018] The pH value of the blood sample diluent is 6.0-8.0.
[0019] The diluent for blood analyzers of the present invention can improve the stability of blood sample components from various aspects, satisfying that after the blood sample is placed in the pre-dilution mode for a long time, the white blood cell classification characteristics remain unchanged, and the red blood cell MCV remains stable, and does not change with temperature. change with change.

The invention discloses diluent for a blood analyzer. Each liter of the diluent for a blood analyzer comprises 5-10g of sodium chloride, 8-12g of sodium sulfate, 0.1-0.3g of edetic acid, 0.2-0.8g of potassium chloride, 1-3g of imidazole, 0.1-5g of purine compounds, 1-3g of preservatives, 0.01-0.1wt% polyoxyethylene alkyl ethers, and has the pH value of 6.0-8.0. The white blood cell classification property as well as the stability of MCV (mean corpuscular volume) and blood sample substances in a blood sample specimen can be kept by adopting the diluent for the blood analyzer, and meanwhile, when the environment temperature changes, the MCV value of a blood sample is still at the stable level; moreover, purine compounds are added in a reagent, so that the stability of blood cells in a pre-diluted sample is improved, and a white blood cell three-cent histogram is kept stable; and a reagent contains non-ionic surface active agents, and the osmotic pressure is adjusted, so that the red blood cell volume in the pre-diluted sample is kept keeps to stable.
Description
technical field [0001] The invention relates to the technical field of reagents for blood analyzers, in particular to a diluent for blood analyzers. Background technique [0002] Blood cell analysis is the most commonly used item in clinical testing, generally by taking blood samples from the human body and then analyzing the blood cells in the blood samples, including hemoglobin (HGB), red blood cell count (RBC), white blood cell count (WBC), platelet count (PLT), hematocrit (HCT), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC) and other parameters. [0003] When measuring the above parameters of the extracted blood sample, due to the blood sample itself is easy to coagulate, the cell protein or material components are prone to chemical reaction decomposition, or the death of the blood sample after isolation, etc., the blood sample detection cannot be performed accurately. . Therefore, in order to maintai...
