Introduction

In 1954, Seegers et al: first divided antithrombin into four types, and since then, the name of antithrombin III has been used: international health organization (WHO) established the first generation of international reference material (72/1) in 1978, which used the name of antithrombin Ⅲ: by the UK National Biological The second generation of international reference materials (93/578) prepared by NIBSC and established by WHO in:1994, the third generation of national reference materials in:2010 The international reference product (08/258) no longer uses the nomenclature of "antithrombin III", but uses the nomenclature of "antithrombin": International Thrombosis and Hemostasis Antithrombin (ISTH) is also the term nomenclature: There are two types of products listed in the domestic market: antithrombin III assay kit and Antithrombin Assay Kit: Although the terminology and the names of international reference products have been unified internationally, in view of the fact that the names of international products use According to the actual registration situation of domestic products, antithrombin III is still used in the name of this standard: The international unit of plasma antithrombin was established through a multi-center joint study based on the assignment of normal pooled plasma from each laboratory of: Each laboratory's pooled normal plasma was defined as 1 IU, and the public mean was assigned to the standard: Currently, many coagulation diagnostic products Manufacturers use "%" values in their calibration plasma, where 100% is equivalent to 1 IU, and in their calibration plasma and/or diagnostic kits: marked in the relevant documentation: Therefore, the use of "%" for plasma calibration or quality control is perfectly acceptable: YY 1741-2021 Antithrombin III Assay Kit

1 Scope

This standard specifies the requirements, test methods, labels and instructions for use, packaging, transportation and storage of antithrombin III assay kits: This standard applies to the antithrombin III assay kit (hereinafter referred to as the kit) based on the chromogenic substrate method of heparin cofactor activity, not A kit suitable for measuring the mass concentration of antithrombin III by turbidimetry:
