1 in 20

Pregnancies are incorrectly classified as high risk.

1 in 10

Fetuses with down syndrome are not detected when using conventional screening (false-negative results).

1 in 700

Children born in Nigeria have Down Syndrome.

NeoBona is the new generation of screening for non-invasive prenatal diagnosis.

It detects the most common chromosomal abnormalities occurring during pregnancy by analyzing the fetal DNA present in the mother’s blood. 

NeoBona detects the most frequent chromosomal abnormalities that occur during pregnancy by studying the cell-free fetal DNA present in maternal blood.



Benefits of NeoBona

  • Accurate – Overall detection rate is higher than 99% for Down’s, Edwards, and Patau Syndrome.
  • Simple – A single blood sample from the mother is all that is needed.
  • Safe – The test is non-invasive and carries no risk to the fetus
  • Fast – Results are typically available in 10 working days.
  • Advanced – The analysis is based on cutting-edge technology from Illumina, a world leader in DNA sequencing

Why choose NeoBona?

  1. Confidence
    NeoBona offers parents assurance that chromosomal abnormalities in the fetus can be detected early during pregnancy. A non-invasive test does not carry any risk to the future baby.
  2. Professional Counseling
    Genetic counselling is recommended before a NeoBona test. NeoBona is the only prenatal test available that has the support of a team of over 1,000 medical professionals and genetics experts who work closely with your doctor.
  3. Fetal Fraction
    Unlike other prenatal tests, NeoBona specifically analyses cell-free fetal DNA through sizing technology, improving the accuracy of the result. This innovation through technology, developed by Illumina, a world leader in DNA sequencing, integrates state-of-the-art technology and know-how to offer an innovative non-invasive prenatal test.
  4. Next-generation Bioinformatics
    The innovative algorithm generates the TSCORE (Trisomy Score) using the depth of sequencing, the percentage of cell-free fetal DNA, and the quantification of total and fetal DNA fragments to obtain reliable results even at a low fetal fraction.
  1. Accuracy
    Conventional first-trimester screening consists of blood and ultrasound analysis and provides only a statistical risk index. NeoBona directly analyses cell-free DNA and so provides a greater accuracy: better detection and fewer false positives.
  2. Specificity
    Conventional first-trimester screening has a specificity of 95%. In other words, out of every 100 healthy pregnancies, five are incorrectly classified as high risk, leading to anxiety, counselling, and further testing, including prenatal diagnosis. The very high specificity of NeoBona reduces the number of false-positive results to less than 1 in 1,500 pregnancies.
  3. Sensitivity
    Conventional first-trimester screening has a sensitivity of about 90%: out of every 100 fetuses with Down syndrome (trisomy 21), ten would not be detected (false-negative results). The overall sensitivity of neoBona for Down’s, Edwards, and Patau’s syndromes is higher than 99%.

Chromosomal abnormalities detected through NeoBona:

Neobona detects the most frequent trisomies. A trisomy is caused by the presence of an additional copy of a chromosome instead of the normal two. NeoBona detects the following trisomies:

Trisomy 21 (Down's syndrome)

Children affected by this can have mild to moderate intellectual impairment, heart defects, and/or other disorders.

Trisomy 18 (Edward's syndrome)

Affected infants typically have severe malformation and mental impediments and rarely survive beyond one year of age. 

Trisomy 13 (Patau's syndrome)

Infants with Patau syndrome have severe mental impediments, can exhibit severe congenital heart malformations and other pathologies, and rarely survive beyond one year of age.

Klinefelter’s syndrome

Affects males when the normal male karyotype, 46, XY, has at least one extra X chromosome. It is characterised by small testes, low or no sperm cells, breast buds in puberty, and behavioural problems.

Turner syndrome

The absence of a single X chromosome in the female. During childhood, girls may have short stature, and in later life, they have problems with puberty and fertility.

Fetal sex is an optional extra. It is also available for twins. If the ‘fetal sex’ option is selected in twin pregnancies and the presence of the Y chromosome is detected, at least one of the fetuses is male.

Frequently Asked Questions

If you are still unsure about this test, here are some questions that we usually get asked.

Still need answers?

I am pregnant. Is NeoBona suitable for me?

NeoBona is available from 10 weeks of pregnancy. 

NeoBona can be performed in cases of assisted reproduction, including IVF, after donor eggs and sperm are used. It is suitable for twin pregnancies

NeoBona is a genetic screening test and, as such, must be prescribed by your physician.


How does prenatal genetic testing help you?

Peace of mind: Genetic testing answers questions you might have concerning your baby’s health.

Quality decisions: When you have these answers, you are equipped with information that helps you decide the best ways to prepare for you and your baby.

 Adequate planning and preparation: It gives you time to plan for your baby’s needs with regards to implementing the decision you have chosen and are also aware of what outcomes to expect.

Why should I consider NeoBona in my pregnancy?

Age: Babies of pregnant women who are aged 35 years and above have an increased chance of having a chromosomal abnormality.

Family history: If a member of the parent’s family or any of their children has a chromosomal abnormality, it increases the risk for current pregnancy. 

Birth defect in a previous baby: Having had a live-born baby with a birth defect or a stillborn baby—even when no one knows whether the baby had a chromosomal abnormality—increases the risk of having a baby with a chromosomal abnormality.

Miscarriages: Having had several miscarriages may increase the risk of having a baby with a chromosomal abnormality.

Chromosomal abnormality in a prospective parent – A chromosomal abnormality in one or both parents increases the risk, even if the affected parent is healthy and has no physical sign of the abnormality.
