Key facts

Chromosome analysis in Blood by Microarray

Chromosome analysis

This term represents chromosomal analysis by microarray is a high-resolution method for detecting genomic copy number changes and structural variations in blood samples. This technique can identify aneuploidies, deletions, duplications, and other chromosomal abnormalities across the entire genome. Microarray analysis provides detailed information on copy number variations and can detect submicroscopic aberrations that may not be visible through conventional karyotyping. [PMID24053112]
