Embodiment Construction
[0035] A device for detecting fetal chromosomal aneuploidy based on a single sample of peripheral blood, including:
[0036] Sequencing data processing unit: used to compare the nucleotide sequence obtained by sequencing with the standard sequence of the human genome to determine the chromosome corresponding to the nucleotide sequence;
[0037] Result analysis unit: The nucleic acid sequences belonging to the same chromosome are divided into short sequences and long sequences. The length of the short sequence is 101~150bp and the length of the long sequence is 151~200bp; when the chromosome is an autosome, it belongs to the same chromosome When there are more short sequences than long sequences, it is judged that the chromosome to be tested is an aneuploid chromosome.
[0038] The amount of short sequences belonging to the same chromosome is more than that of long sequences, which means that the amount is statistically significantly different, that is, the P value is less than 0.05. ...
