Abstract

The invention relates to the field of quality control of blood coagulation detection of a clinical thromboelastography, in particular to a thromboelastography quality control material and a preparation method thereof. The preparation method of the thromboelastography quality control material comprises the following steps of step 1, collecting fresh pig whole blood and separating plasma; step 2, dividing the plasma into two parts, wherein the first part is used for extracting fibrinogen and a blood coagulation factor, and the second part is used for properly diluting to obtain diluted plasma; step 3, adding extracted fibrinogen and blood coagulation factor into the diluted plasma to obtain a mother solution, and adjusting an R value, a K value, an Angle value and an MA value to be within the ranges of L1 and L2; step 4, performing subpackage and freeze drying on the solution obtained in the step 3 to obtain a final product. The quality control material prepared by the preparation method disclosed by the invention has two specifications of L1 and L2 and is good in stability; the demand that quality control over normal and abnormal blood samples is simulated in a test room can be met.

Description

technical field [0001] The invention relates to the field of quality control of blood coagulation detection items of a clinical thromboelastography instrument, in particular to a quality control product of a thromboelastography instrument and a preparation method thereof. Background technique [0002] Thromboelastography is used to monitor the coagulation state of blood samples to assist clinical evaluation of patients. Thromboelastography is widely used in the monitoring of postoperative bleeding and (or) thrombus formation during or after cardiac surgery, organ transplantation, tumor and radiotherapy. [0003] The instrument adopts the coagulation method to simulate the physiological blood coagulation conditions, and some reagent is added to start the blood coagulation reaction, so that the fibrinogen in the sample is converted into cross-linked fibrin, so that the sample coagulates. The motor inside the instrument drives the sample cup carrying the blood sample to rotate...
