NeoBona ®, non invasive prenatal testing
At Clínica Tambre we recognise and apply the most advanced and state-of-the-art techniques and technologies that complement our assisted reproductive treatments, not only during initial treatment but also during the pregnancy itself.
NeoBona® is a test that is performed through a simple blood test and has the ability to detect three of the most common trisoms in the fetus:: Down syndrome, Edwards syndrome and Patau syndrome, as well as two sexual chromosomal alterations: Turner syndrome (45,X) and Klinefelter syndrome (47,XXY)
The test usually performed during the first trimester of a pregnancy is conventional screening, which only identifies the statistical risk index of the fetus having any of the syndromes mentioned above which are classified as ‘low’, ‘intermediate’ or ‘high’ risk.
However, thanks to SYNLAB, the European leader in diagnostic testing, neoBona® has been developed to provide more accurate information to prospective parents about the genetic status of their baby. The test analyses the amount of cell-free fetal DNA present and can also reveal the gender of the baby.
How and when can I undergo the neoBona® test?
The woman has to give a blood sample from the 10th week of gestation which can be conveniently done at Tambre. Our Nursing Team will then send the sample to the lab who will contact you directly in approximately five working days with the result.
Why choose neoBona®?
The overall sensitivity of neoBona® for the detection of Down, Edwards and Patau syndromes is greater than 99% (compared to 90% with conventional, screening), thanks to the state-of-the-art bioinformatics algorithm, TSCORE. Its specificity is also noteworthy, as it reduces the number of false positives to below 6%. In addition, this noninvasive prenatal test is suitable for twin pregnancies and patients who have received assisted reproductive treatment, even when the IVF process included a gamete donation.
Neobona® is reliable, fast, accurate, simple and safe.
