Laboratory assay overview
Chromosomal microarray (CMA) detects aneuploidies, deletions and duplications below the resolution of chromosome analysis (karyotyping), and long continuous regions of homozygosity. This assay may be useful for investigation of fetuses with abnormal ultrasound findings, abnormal prenatal screening, definition of unbalanced cytogenetic abnormalities, and follow-up to a documented chromosome or microarray abnormality in a sibling or a parent. Microarray analysis may also be used as follow up for a family history of a previous child with developmental delay, intellectual disability, and/or congenital malformations.
