Scope
GB/T 41521-2022 is the English-translated version of 多指标核酸恒温扩增检测微流控芯片通用技术要求.
GB/T 41521-2022 is the Chinese general technical requirement for microfluidic chips used to amplify and detect several nucleic acid targets at once at a constant temperature.
It gives the classification and nomenclature of these chips and specifies the requirements, the test methods, the signs, labels and instructions for use, and the packaging, transport and storage requirements.
It applies to multi-index nucleic acid isothermal amplification and detection products that use a microfluidic chip as the carrier, and it does not apply to chips that carry other biological function modules such as nucleic acid extraction or purification.
It defines the microfluidic chip itself, taking the definition from GB/T 27990-2011 with modifications, and it cites GB/T 191, GB/T 21415-2008 and GB/T 29791.1. It was issued on 11 July 2022 and has applied since 11 July 2022.

Foreword
This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules of Standardization Documents" drafted.
1 Scope
This document specifies the classification and nomenclature, requirements, test methods, signs, labels and instructions for use, packaging, transportation and storage requirements of multi-index nucleic acid isothermal amplification detection microfluidic chips.
This document applies to multi-index nucleic acid isothermal amplification detection products using microfluidic chips as carriers.
This document does not apply to microfluidic chip products containing other biological function modules, such as microfluidic chips containing nucleic acid extraction, nucleic acid purification and other functions control biochip products.
2 Normative references
The contents of the following documents constitute essential provisions of this document through normative references in the text. Among them, dated citations documents, only the version corresponding to that date applies to this document; for undated references, the latest edition (including all amendments) applies to this document.

3 Terms and Definitions
The terms and definitions defined in GB/T 21415-2008, GB/T 29791.1 and the following apply to this document.
3.1 Microfluidic chip
Using silicon, glass, metal materials, macromolecular polymers and other materials as chip substrates, it is processed by micro-nano processing, precision injection molding and other processing technologies It consists of one or more functional units such as micro-pipes, micro-valves, and micro-reaction pools, which can complete the precise control of liquid flow in the chip. Thereby realizing a specific biochemical reaction function of the biochip. [Source: GB/T 27990-2011, 2.2.2, with modifications]
3.2 Multi-index nucleic acid isothermal amplification and detection
A certain method or product can simultaneously amplify and detect multiple (usually more than 2) nucleic acid target sequences to be detected in a sample at a constant temperature.
Note: The nucleic acid target sequences to be detected are from multiple nucleic acid target sequences in a certain category such as bacteria, viruses, parasites, fungi, etc., or from multiple nucleic acid target sequences in multiple categories Nucleic acid target sequences.
