POC Portfolio - FR Canada

Description

What is POC testing?
Advantages
Use and limitations

Our POC portfolio consists of:

POC by Next Generation Sequencing (NGS)
POC by Chromosomal Microarray (CMA)
Non-invasive POC (niPOC)

What is POC testing?

Our portfolio of POC tests analyse whether a miscarriage may have been caused by a
chromosomal abnormality.

In around 50% of first trimester miscarriages a chromosome abnormality is present.
This figure rises to 60% in cases of assisted reproductive treatment and further increases with age.
The POC test analyses the chromosomes and is able to identify alterations to the number of chromosomes (aneuploidies) as well as losses and gains of chromosome fragments.
For POC (by CMA and by NGS) it is possible to identify some types of ploidy alterations (loss or gain of a complete set or sets of chromosomes) and determine the origin of the tissue under study (foetal or maternal).

How is the POC test performed?

There are different methods depending on the test carried out:

niPOC Methodology

**It is essential that the blood sample is collected before the evacuation of the foetal tissue takes place. If pharmacological treatment is being used for the evacuation, the blood should be collected prior to taking the medication.

POC Methodology

For POC by NGS and POC by CMA

Why perform POC testing?

Chromosomal analysis of foetal tissue by means of the POC test is a valuable
tool to investigate the cause of the miscarriage and offer reproductive
counselling to the patients.
We offer three types of POC testing to adapt to the needs of each patient: POC (by CMA), POC (by NGS) and niPOC (non-invasive POC).
Informative results are obtained in 86% of cases.
Determines whether the analysed tissue is from the foetus or the mother.
POC (by CMA and NGS) allows identification of most polyploidies.
POC (by CMA and NGS) can be performed on twin pregnancies.

Who is the POC testing?

The testing can be carried out for any individuals or couples who have experienced a miscarriage, but is particularly recommended for patients who have experienced multiple miscarriages and those undergoing assisted reproductive treatment.

Limitations of POC testing

This method does not detect balanced structural chromosomal abnormalities and might not detect the following: aneuploidy in low-level mosaicism, some forms of tetraploidy (for POC by NGS), uniparental disomy, conditions caused by variants in single genes and deletions or duplications smaller than 10 Mb.
The chance of a non-informative result is increased for miscarriages that occur before six weeks’ gestation.

Igenomix et la fertilité

Nous travaillons à créer un monde dans lequel l’infertilité n’est plus un obstacle impossible à surmonter. En collaboration avec des cliniques et des médecins spécialisés dans le domaine de la fertilité dans le monde entier, nous étudions la reproduction humaine pour changer la vie des couples qui essaient d’avoir un enfant.
