What is the Neo 24 NIPT test?

The Neo 24 NIPT test is one of the latest non-invasive prenatal pregnancy screening tests available. The test is completely safe for the mother and her unborn baby. The Neo 24 NIPT test will analyse the 24  chromosomes and enables assessment for a wide variety of chromosome abnormalities that can lead to a late miscarriage or the birth of a child with a serious congenital condition. Neo 24 offers a high detection rate for the specific chromosome abnormalities tested and a low false positive rate.

Neo Test offers a high detection rate for the specific chromosome abnormalities tested and a low false-positive rate. Importantly, the non-invasive nature of the test means that it does not increase the risk of miscarriage – unlike traditional invasive prenatal tests

What are the key features of the Neo 24 test?

  • Completely Safe for Mother and Pregnancy with no risk of miscarriage.
  • Potentially examine all 24 types of chromosomes
  • High detection rate for specific chromosomes abnormalities tested
  • Extremely low false-positive rate
  • Results in 5 days*
  • Far less ‘no results’ than other tests
  • Enhanced reassurance
  • from 10+ weeks 

This test allows women who are at least 10 weeks gestation to be screened for chromosomal abnormalities.

What does the Neo 24 screen for?

  • Down’s syndrome
  • Edwards syndrome
  • Patau syndrome
  • Turner syndrome
  • Klinefelter syndrome
  • XYY syndrome
  • Trisomy X syndrome

It is available for single including donor or surrogate and twin pregnancies. You can also choose to find out the sex of your baby**.  

How is the Neo 24 test performed?

The Neo 24 NIPT test involves a simple and safe blood test whereby a small quantity of blood is collected from the mother usually via a vein in her arm. The blood is then sent to the lab and analysed for cell free DNA (cfDNA), circulating fragments of fetal DNA. These are derived from the maternal placenta, the organ providing nutrition to baby, and are circulating in the mother’s blood stream. The results determine if there is a high or low probability of baby having the conditions screened for. 

Where are the test samples analysed?

The Neo Test is processed and analysed in the UK. 

What are the key differences with the Neo 24 test?

Neo NIPT test has a higher positive predictive value as compared to the combined test (offered by the NHS), which means significantly lower high probability results where the condition is not actually present.

Neo24 analyzes all 24 chromosomes for enhanced detection of abnormalities and greater reassurance.

The Neo Test can be performed for the majority of pregnant women, however is particularly recommended for

  • parents who wish to avoid unnecessary invasive testing, which carries a risk of miscarriage
  • women over 35 years of age
  • parents that have had a high probability result in their current or previous pregnancies 
  • confirmed chromosomal condition in a previous pregnancy

Please note that blood thinners can increase the possibility of receiving no results.

* Vast majority of results are within 5 working days.  

**Please note in some instances the NIPT test may not be able to determine the sex.  

In monochorionic (identical) twin pregnancies NIPT test can confirm the sex of each twin as it will be the same. For dichorionic (non-identical) twin pregnancies can confirm if there are 2 girls, but can only confirm the presence of 1 boy.
