The Cytogenetics Laboratory was the first laboratory developed at CGC Genetics.

With over 20 years of experience, this lab brings together a team of professionals solely dedicated and specialized in this area, using the latest technology such as chromosomal microarray analysis (or Array CGH).

Chromosomal microarray analysis is performed by CGC Genetics using the best international technology available (CytoScan®, Affymetrix®).

Array CGH offered by CGC Genetics includes the highest analytical resolution (750K or 2.7M) along with a clinical interpretation performed by our medical geneticists.

The laboratory processes about 9 000 tests per year of different medical specialties, from Prenatal Diagnosis, Hemato-Oncology, Reproductive Medicine to Pediatrics, with reduced turnaround times.

Currently, the CGC Cytogenetics Laboratory is responsible for more than 35% of all the Prenatal Diagnosis tests performed in Portugal.
