Reference range/Unit	[Whole Blood] See comments in the report
Clinical Significance	This test utilizes the Affymetrix Dx gene chip to perform a high-resolution microarray analysis, detecting gene deletions and duplications across the entire genome. Unlike conventional chromosomal analysis, this method can identify numerous microdeletions and duplications that would otherwise be undetectable. Additionally, it can detect loss of heterozygosity (LOH), which may lead to uniparental disomy (UPD).
