Your future baby's health and yours are our priority

Need to have the Array CGH test done?

Do it with expert care and the latest technology to ensure that your pregnancy benefits from the safety of the most recent developments in prenatal genetic analysis.

Don't think twice. Get peace of mind.

Molecular prenatal diagnosis (Array CGH)

What is it

Array CGH (Comparative Genomic Hybridisation) or prenatal molecular karyotyping is a latest generation genetic diagnosis technique used to diagnose chromosomal anomalies with a superior resolution to conventional techniques (conventional cytogenetic analysis that studies the structure, function and behaviour of chromosomes).

This test is a tool for studying the human genome quickly and accurately to detect DNA alterations, including microdeletions and duplications.

The stages of the technique are:

  • A sample of the placenta or amniotic fluid is obtained by chorionic villus sampling.
  • We study the sample with thousands of probes that analyse the number of copies of small DNA fragments and compare them to a reference sample.


Because this technique does not require cell culture, we can have the test results back within 7 days so the waiting time is reduced.

Molecular prenatal diagnosis (Array CGH) - What is it?

Who is it for

Your gynaecologist must indicate the Array CGH test for you. They usually recommend it if:

  • You have a family history of chromosomal abnormalities
  • You have a family history with an increased risk of developing abnormalities
  • You have suffered from recurrent miscarriage
  • An abnormality was detected on your ultrasounds
  • Alterations were detected in your biochemical screening

If you have any questions, ask your gynaecologist or the clinical geneticist at our clinic.
