During pregnancy, there are several checkpoints to determine (as far as possible) whether the fetus will develop a disease. At NIMGenetics we want to be there for you during this stage.
The combined first trimester screening is focused, fundamentally, on Down Syndrome (trisomy 21). This test involves a biochemical analysis and an ultrasound scan (in some cases, two). The result of this process indicates the risk of the baby being born with a genetic syndrome. When this risk exceeds a certain threshold, an invasive test (amniocentesis or chorionic villus sampling) may be considered. These tests are fully confirmatory, but carry a risk of miscarriage. Today, pregnant women have a new tool available to them in the form of TrisoNIM®, the maternal blood fetal DNA test that can safely provide genetic information about the baby.
This is a screening test with a near-100% sensitivity for trisomies 21, 13 and 18. Therefore, these conditions can be ruled out with a very similar reliability to invasive tests, but without any risk to mum or baby. Geared towards a global genetic approach, TrisoNIM® assesses the risk of the baby being a carrier of aneuploidies in the other chromosomes, while also determining the fetal sex by analysing the sex chromosomes. Furthermore, the different types of TrisoNIM® test allow other regions of the genome to be analysed and reported on, including microdeletion syndromes and dominant monogenic disorders.

We want to support you on the most important journey of your life.
To order a TrisoNIM® it is imperative to have a medical prescription. Ask your gynecologist to inform you in detail. Check here to know about the process. If you do not have an assigned professional, contact us.

Microdeletions consist of the loss of chromosomal material; and microduplications, in profits. In both cases, they occur in contiguous gene blocks and, due to their small size, cannot be detected by conventional chromosome analyses. These alterations constitute a broad group of serious pathologies that, despite their low individualized incidence, occur, as a whole, with a high frequency in the population.
(2) Monogenic hereditary diseases are caused by a variation in the DNA sequence of a single gene. In the case of autosomal dominant diseases, only one of the two copies of the gene must be altered for the person to develop the disease. The probability of passing the altered copy to the offspring is 50%, since the parent will have a healthy copy and a diseased copy.

By only needing to test the mother’s blood, it avoids the risk of miscarriage following amniocentesis.
ENAC accreditation ISO 15189 Standard for fetal aneuploidy screening (chromosomes 13, 18, 21, X and Y), as well as for maternal blood fetal sex determination through massive parallel sequencing (NGS). Certified by Bureau Veritas, in accordance with the requirements of theISO 9001:2015, Standard, for providing genetic testing services in pre-analytical, analytical and post-analytical stages for the specialities of genomics, non-invasive prenatal testing and molecular diagnostics.
Combines next-generation sequencing technology with the most advanced bioinformatics analysis. Uses a dual analysis algorithm to improve accuracy, both in risk calculation and in fetal fraction, which is crucial to the reliability of the test. This value is calculated rigorously and in detail, in accordance with international recommendations.
NIMGenetics has carried out over 50,000 prenatal tests and more than 60,000 maternal blood fetal DNA tests.
TrisoNIM® is a flexible service that adapts to your needs. It includes different types of analysis that mainly differ in the number of syndromes being tested. If you would like the most complete test, TrisoNIM® NeoSeq is the one for you.
A high-risk result following a fetal DNA test must be confirmed by an invasive test. In these cases, NIMGenetics offers you KaryoNIM® Prenatal, a diagnostic test that analyses 124 syndromes quickly and efficiently, free of charge.
NIMGenetics has the best technical and medical team specialising in prenatal genetic testing, with Medical Genetics experts and members of the Spanish Association of Prenatal Diagnosis (AEDP) and the Spanish Association of Human Genetics (AEGH). We are endorsed by the most powerful genomics company in the world (BGI).
