FAQs

Who can be tested?
The NIFTY® test is available to any woman from week 10 of pregnancy.
What does the NIFTY® test tell me?
The NIFTY® test tells you your risk of having a baby with Down Syndrome, Edwards Syndrome or Patau Syndrome. Although NIFTY™ tests with 99.5% accuracy for these conditions, as a screening test it does not tell you with 100% accuracy that your baby does or doesn't have one of these conditions.
The NIFTY® test also provides optional testing for certain deletion syndromes and sex chromosomal aneuploidies at no extra cost.
In addition, the NIFTY® test can also provide gender information should you wish to know.
How does the NIFTY® test work?
Cell free DNA originating from the fetus is present in the mother's blood circulation during pregnancy. By taking a small maternal blood sample, NIFTY® analyses this cell free fetal DNA on genetic sequencing machines to see whether any chromosomal abnormality is present.

For more information please visit the 'Science Behind NIFTY®' page on our website or watch our introductory video where the test methodology is explained in further detail.
How accurate is the NIFTY® test?
NIFTY® is accurate to 99.5% for detection of Down Syndrome, Edwards Syndrome and Patau Syndrome.
This figure is quoted based on validation studies listed within this website.
It is important to note that NIFTY® is a screening test, which means that it does not test with 100% accuracy like an invasive diagnostic procedure such as amniocentesis.

 

 
When will I get my results?
Results are typically available within 10 working days from the healthcare provider who conducted your NIFTY® test.
What is a false positive result?
A false positive result is classified as when a result comes back as positive for a condition when in fact subsequent confirmatory diagnostic testing shows the fetus not to have the condition.

NIFTY® has a false positive rate of 0.1%.
What’s the difference between a diagnostic test and a screening test?
A diagnostic test is one that tests with 100% accuracy and definitively tells you whether a condition exists or not. The drawback for diagnostic prenatal tests such as amniocentesis is that they carry a risk of miscarriage.

A screening test indicates the risk of having a condition, and while they may be highly accurate, do not test with 100% accuracy.

NIFTY® is a screening test, so while it has a very high level of accuracy at 99.5% for detection of Down Syndrome, Edwards Syndrome and Patau Syndrome, it is not diagnostic.
How much does the NIFTY® test cost?
The price of NIFTY® varies depending on your country and healthcare provider. Please contact your healthcare provider for more information. If you are not sure where your nearest NIFTY® provider is located, then please contact us via the contact form in our website.
What do I do if I get a high-risk result?
You should always review your results with your healthcare provider. We advise that in the event of a high-risk result, you undertake follow up confirmatory diagnostic testing.
