GB/T 29791.2 Information provided by manufacturers of in vitro diagnostic medical devices (labeling) Part 2.Professional in vitro diagnostic reagents 3 Terms and definitions The following terms and definitions apply to this document. 3.1 Nucleic Acid A class of biological macromolecules connected by nucleotides or deoxynucleotides through 3',5'-phosphodiester bonds, which have very important biological The function is mainly to store and transmit genetic information, including ribonucleic acid (RNA) and deoxyribonucleic acid (DNA). 3.2 Magnetic beads The surface of superparamagnetic nanoparticles has been improved and modified to make it bind with nucleic acid molecules specifically and efficiently under different conditions. Combining and dissociating, such superparamagnetic nanoparticles are called magnetic beads. Using this feature of magnetic beads, under the action of an external magnetic field, Separation and purification of nucleic acid DNA and RNA from the sample. 3.3 Extraction yield A nucleic acid extraction kit (magnetic bead method) is used to extract the total amount of nucleic acid from a biological sample of a certain mass or volume. 3.4 Nucleic acid purity The amount of nucleic acid relative to other impurities in the product extracted from a certain amount of biological sample with a nucleic acid extraction kit (magnetic bead method). 3.5 Precision Under specified conditions, repeat measurements on the same or similar measured objects to obtain the measured values or the degree of agreement between the measured values. Note 1.Measurement precision is usually represented by imprecision in numbers, such as standard deviation, variance and coefficient of variation under specified measurement conditions. Note 2.Prescribed conditions such as measurement repeatability conditions, measurement intermediate precision conditions or measurement reproducibility conditions. Note 3.Measurement precision is used to define measurement repeatability, intermediate measurement precision and measurement reproducibility. Note 4.Repeated measurement refers to the results obtained on the same or similar samples in a way that is not affected by previous results. [GB/T 29791.1-2013, A.3 Supplementary Statistics and Analysis Terms] 4 categories 4.1 Classification by extraction target type According to the different types of extraction targets, it can be divided into human genomic DNA extraction kits, pathogen nucleic acid extraction kits and other nuclear There are three types of acid extraction kits; pathogen nucleic acid extraction kits can be divided into bacterial nucleic acid extraction kits and virus nucleic acid extraction reagents Boxes etc. Note. Other types of nucleic acid extraction kits refer to multi-purpose kits that can extract both human genomic DNA and pathogen nucleic acid. 4.2 Classification by extraction target nucleic acid type According to different types of extraction target nucleic acid, it can be divided into deoxyribonucleic acid (DNA) extraction kit and ribonucleic acid (RNA) extraction kit. 5 Technical requirements 5.1 Appearance The appearance should meet the following conditions. a) The kit should meet the appearance requirements specified by the manufacturer; b) The kit should have complete components, clean packaging, no leakage, and no damage; signs and labels should be clearly written. 5.2 Quantity The amount of liquid reagents should not be less than the value indicated on the label. 5.3 Extraction yield The extraction yield of the kit should meet the extraction yield requirements specified by the manufacturer.
