What is Microarray?

Microarray, Array Comparative Genomic Hybridization (a-CGH) is a high-tech technique used to detect small add-ins and small drop-outs that cannot be observed by a microscope. With this method, chromosome or chromosome regions increases and decreases can be detected in the whole genome. In cases of suspicion of DNA content changes of deletion or duplication which is less than 5Mb where cytogenetic methods (see Cytogenetics) are insufficient can be are examined at high resolution, therefore it is quite reliable.

When Microarray method is needed?

​It is mostly directed at children and can be used in the diagnosis of mental and gender related or physical development disorders. aCGH method is possible to use in prenatal and postnatal period. Preimplantation genetic diagnosis (PGD) is a method used to increase treatment success and decrease pregnancy losses in couples with recurrent miscarriage, recurrent failed in-vitro trials and repetitive failures.
