[0055] 1. Samples for measuring electrical characteristics

[0056] The sample for measuring electrical properties according to the present technique is used for measurement of electrical properties, and contains at least a liquid containing a blood coagulation factor, and fine particles. The sample for measuring electrical properties is suitable for measuring the electrical properties of a blood sample to be measured, and is useful for verification of measurement accuracy. Thus, hereinafter, the sample for electrical characteristic measurement according to the present technique will be referred to as a "control sample" in some cases.

[0057] Using a control sample allows the state (for example, activity, etc.) of the reagent used when measuring the electrical c...

example 1

[0158] As microparticles each having a density lower than the plasma density, polymer beads (manufactured by Matsumoto Yuka Pharmaceutical Co., Ltd., manufactured by Matsumoto Microsphere Co., Ltd.) enclosing a shell of a low-boiling point hydrocarbon and an acrylonitrile copolymer were used, and the polymer beads were divided into 5 % proportion dispersed into PBS. Freeze-dried plasma was dissolved by bead dispersion to prepare samples for QC.

[0159] Various reagents such as an aqueous calcium solution, an intrinsic stimulant reagent, or an extrinsic stimulant reagent are put into the cartridge, and the cartridge is placed in the dielectric coagulation meter. At this time, in the case of halving the activity of the reagent, the concentration of the endogenous stimulatory agent and the exogenous stimulatory agent were also prepared in half as a model. After thoroughly mixing the QC sample containing the fine particle dispersion by inversion, place the QC sample in the diele...

Abstract

The objective of the present invention is to provide a technique useful for verifying measurement accuracy when measuring the electrical characteristics of a blood sample, prior to the measurement being performed. Provided is a sample for measuring electrical characteristics, including at least a liquid containing a blood coagulation factor, and microparticles, wherein the density of the microparticles is different from the density of the liquid containing the blood coagulation factor. Also provided are a device for measuring electrical characteristics and a method for measuring electrical characteristics, which employ said sample for measuring electrical characteristics.

Description

technical field [0001] The present technology relates to a sample for measuring electrical characteristics, an electrical characteristic measuring device, and a method for measuring electrical characteristics. Background technique [0002] Drug therapy is administered in a prophylactic manner against the risk of thrombosis, antiplatelet drugs, or anticoagulants. In such prophylactic administration, there are side effects in case of overdose, increased risk of bleeding. In order to obtain a sufficient preventive effect while preventing this side effect, the blood coagulation ability of the administered subject is promptly evaluated. [0003] In recent years, the development of techniques for conveniently and accurately evaluating the degree of blood coagulation has been carried out. For example, Patent Document 1 discloses a technique for acquiring information related to coagulation from the dielectric constant of blood. Therefore, in Patent Document 1, it is described tha...
