Problems solved by technology

[0006] However, the existing methods are not wide in detection sensitivity and linearity. When used in clinical detection of D-D dimer, they are often constrained by insufficient linearity of high-concentration samples or low detection sensitivity of low-concentration samples.

Abstract

The invention discloses a high-sensitivity high-linearity D-D dimer detection kit and an application method thereof. A reagent one is a 30mmol / L trihydroxymethyl aminomethane buffer solution. A reagent two comprises a mixed liquid of large-diameter mouse-anti-human D-D dimer monoclonal antibody latex particles with a concentration of 0.01-0.04% (w / v) and small-diameter mouse-anti-human D-D dimer monoclonal antibody latex particles with a concentration of 0.05-0.2% (w / v). Specific antibody content in the small-diameter mouse-anti-human D-D dimer monoclonal antibody latex particles is 0.05-10% of that in the large-diameter mouse-anti-human D-D dimer monoclonal antibody latex particles. Through optimizing the average diameter of large and small particles and concentrations thereof in the reaction system, D-D dimer high-sensitivity detection under low-concentration situation can be realized, and detection range under high-concentration situation can be expanded.

Description

technical field [0001] The invention relates to the field of biological sample detection, in particular to a kit for improving the detection sensitivity and detection range of biological samples by using two types of latex particles with different average diameters, and a method for using the same, in particular to a highly sensitive, high Linear D-D dimer detection kit and method of use thereof. Background technique [0002] D-dimer (D-D dimer) is derived from cross-linked fibrin clots dissolved by plasmin. In the blood coagulation and fibrinolysis system, due to the action of the thirteenth factor of coagulation, the stable cross-linked fibrin is decomposed by plasmin, and the fibrin monomer is cross-linked by activated factor XIII, and then passed through A specific degradation product produced by plasmin hydrolysis is a specific marker of fibrinolytic process. [0003] The increase of D-dimer in the blood proves the formation of thrombus in the body and activates the f...
