More Information
Summary:The present disclosure discloses a method, a device and a system for detecting chromosomal aneuploidy. The method comprises: sequencing at least a portion of a nucleic acid in a sample under test to obtain a sequencing result including reads; aligning the reads to a first reference sequence to obtain an alignment result including specific chromosomes to which the reads are mapped; determining, for a first chromosome, the amount of reads mapped to the first chromosome based on the alignment result; and comparing the number of the reads mapped to the first chromosome with the amount of reads in a negative control mapped to the first chromosome to determine the number of the first chromosome. When the method is employed to detect chromosomal aneuploidy, the detection results acquired have relatively high sensitivity and accuracy.
