Array Platform Modification

Array Platform Modification

Effective update from 15/03/2021

We would like to inform you that we will change the platform used to perform Array study.

The new platform is based on CytoScan 750k and we will start working with it from the date indicated above.

This technology allows the identification of copy number variants (CNV), as well as triploidies detection, evaluation of large regions of absence of heterozygosity (AOH) and uniparental disomy (isodisomies and heterodysomies with case-parent (trio) studies).

The new platform offers the advantage of detection of findings not contemplated with the previous array methodology, including those detected by qf-PCR.

With this platform, it is not necessary to carry out prior qf-PCR study for prenatal/products of conception samples. Even though, we recommend its request, since previous qf-PCR analysis gives us results of common aneuploidies (13, 18, 21, X, Y) in 24-48 hours so we can proceed in most appropriate way with the Array study in each case.

Changes in the test codes are the following:

In case you require it, you can request a qf-PCR study on prenatal or products of conception samples by requesting the following codes:

2817- Aneuploidy (X, Y, 13, 18, 21) QF-PCR, amniotic fluid

3440- Aneuploidy (X, Y, 13, 18, 21) QF-PCR, biological sample

5505- Aneuploidy (X, Y, 13, 15, 16, 18, 21, 22) QF-PCR, products of conception

We remain at your disposal for any further information you may require.

Kind regards,
