ABOUT THE TEST
Chromosomal abnormalities, like trisomy 21 (Down's syndrome), are present in the 1-2% of the fetuses.
neoBona is a non-invasive prenatal test (NIPT) that detects chromosomal abnormalities in the fetus without any risk to the future baby, providing highly reliable results for the screening of:
- Aneuploidies1 most common chromosomes (21, 18 y 13)
- Aneuploidies of the sex chromosomes and fetal sex
1Alteration in the number of copies of a chromosome.
neoBona GenomeWide provides a more complete view of the fetal genome by analyzing los 23 chromosome pairs to expand screening to other rare chromosomal abnormalities2 when evaluating the presence of:
- Anomalies in the rest of the autosomes (non sex chromosomes)
- Deletions and partial duplications3, CNVs of size greater than or equal to 7 Mb in all autosomes
2These anomalies could have clinical relevance as they are associated with pregnancy loss., various structural alterations, fetal abnormalities and developmental and/or growth delays of the fetus.
3 Losses or partial gains of chromosomal regions.
Conventional first trimester screening consists of an analysis and an ultrasound, and provides a statistical risk index. neoBona GenomeWide directly analyzes free fetal DNA, which provides greater reliability and a better detection rate, along with fewer false positives.
The sensitivity of conventional screening is 90%, This means that of each 100 fetuses with Down syndrome (trisomy 21), 10 would not be detected (false negatives). The overall sensitivity of neoBona GenomeWide is greater than 99% for Down syndromes, Edwards and Patau (trisomies 21, 18 y 13).
Unlike other prenatal tests, neoBona GenomeWide analyzes free fetal DNA through a technology that allows determining the size of free DNA fragments, improving the reliability of the result.
IS IT RIGHT FOR ME?
neoBona GenomeWide is indicated for the following cases:
- From the 10th week gestation (10 weeks + 0 days)
- It can be done in cases of rassisted production, including IVF with gamete donation
- It is suitable for twin pregnancies
- It is a genetic screening test and as such must be prescribed by a doctor
PRELIMINARY CONSIDERATIONS
- It is necessary to go to a SYNLAB center to take the test
- It is not necessary to go on an empty stomach
- Necessary medical prescription
WHAT IS THE PROCEDURE?
The test requires a blood sample, so You need to go to a SYNLAB center to take the test so follow the next steps!
