Question

Quizplus · Accepted Answer

Chromosomal microarray (CMA) is the standard test for infants with global developmental delay (GDD) as it can detect genomic imbalances responsible for developmental delay, intellectual disability, and autism spectrum disorders. CMA provides higher resolution and a greater detection rate compared to G-banded karyotyping. fMRI and genome hybridization are not standard tests for GDD.
