GB/T 45214-2025 is the English-translated version of 人全基因组高通量测序数据质量评价方法.
GB/T 45214-2025 is the Chinese national standard covering judging whether a run of human whole genome sequencing data is fit to use — the library type, PCR or PCR-free, the rate at which pooled samples are correctly assigned to their index, the base quality given as the share of bases above Q20 or Q30, the GC content, and the evaluation methods, which cover resequencing against a reference genome and not de novo, haplotype or tumour work. First edition, under the National Medical Products Administration. In force from 1 February 2026. Issued on 24 January 2025, it has been in force since 1 February 2026.

Method for quality assessment of human whole genome high-throughput sequencing data
1 Scope
This document defines the terms and definitions of human whole genome high-throughput sequencing data quality, specifies quality requirements, and describes the corresponding evaluation method.
This document applies to the data quality of whole genome sequencing of human genomic DNA samples using high-throughput gene sequencing technology. evaluate.
This document does not apply to dideoxy chain termination sequencing [Sanger sequencing] technology and single molecule sequencing technology, as well as human samples De novo sequencing, haplotype sequencing, and sequencing of human tumor tissue samples are not applicable to the animal, plant, virus, or bacterial species contained in human samples. Bacteria, parasites, etc.
2 Normative references
This document has no normative references.
3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Perform whole genome sequencing on different human individuals or groups.
Note. Includes 23 pairs of human chromosome nucleic acid sequences and mitochondrial nucleic acid sequences.
3.2 Library
A group of fragment molecules to be sequenced with adapters (DNA fragments of known sequence).
Note. Usually, it is divided into PCR library (a library constructed by a certain number of PCR amplification cycles) according to whether it relies on PCR amplification process.
There are three types of libraries. sequencing library (sequencing library) and PCR-free library (sequencing library constructed directly without relying on PCR amplification process).
3.3
When sequencing multiple samples together, the percentage of sequencing fragments that are correctly identified and assigned labels to the total number of sequencing fragments.
3.4
The percentage of sequenced bases with base recognition quality above the specified threshold to the total number of sequenced bases.
Note. Usually expressed as Q20, Q30, etc.
3.5 GC content
The sum of the number of guanine (G) and cytosine (C) in the sequenced fragment bases accounts for all purine bases [adenine Adenine (A) and Guanine] and the percentage of the total number of pyrimidine bases [thymine (T) and cytosine].
