Microarray can assess several different chromosomal regions at the same time and can identify micro deletions and duplications which cannot be detected by both cytogenetics and FISH. But this test is not useful to detect balanced translocations which are present in cases of Infertility or Bad Obstetric History.
This test is replacing conventional cytogenetics in analysis of abortuse material/POC, prenatal evaluation and neonatal/pediatric cases since culturing is not required.
