Chromosomal Microarray Analysis (CMA) or Microarray is a whole genome test available to detect a wide range of genetic syndromes caused by microdeletions and duplications in the genone. Microarray scans the entire genome at very high resolution using DNA from the individual and provides information on thousands of genes in a single test. It can precisely define which genes are missing or extra.

This test is done using ‘Ultra Low Definition’ (ULD) or ‘Ultra Low Resolution’ chips. This test provides an economical option for using the microarray technology to detect common aneuploidies and certain microdeletion/duplication syndromes.
