Why have an NIPT test? What will I find out?
An NIPT test is a non-invasive blood test that screens for specific chromosomal conditions in pregnancy. The test can be performed from when you are 10 weeks pregnant.

The NIPT test screens for the following conditions:

  • Down's syndrome (T21)
  • Edward's syndrome (T18)
  • Patau's syndrome (T13)

The NIPT test for Down's syndrome is very reliable. The detection rate is greater than 99% and the test has less than a 1 in 1000 false positive rate.

If you choose, the NIPT test can also determine the sex of your baby with 99.6% sensitivity.

This test is suitable for pregnant women aged 18 years and above.

This test is suitable for a single and a twin pregnancy.

Your results will take an average of 10 working days, and these will be communicated directly to you from the laboratory via an online portal. You will be able to track the progress of your results online.

Should any results from your test be abnormal, it is recommended that you contact your midwife to discuss these.

You must also be no earlier than 10 weeks or the blood test will not be accurate.

Receiving your results
When the laboratory has analysed your sample, the results will be sent to Melio together with a detailed PDF report explaining the results. One of Melio's doctors will also review your results and post a personalised medical comment in your Melio account.

When your results are ready, you'll receive an SMS notification to login to your Melio account to access the results.


  • We expect approximately 0.68% of NIPT tests to fail in processing due to the low levels of foetal DNA collected. If this is the case, we will ask for a second sample at no extra charge. In this case a second blood test will be required.
  • The NIPT test is not suitable in cases where there is evidence of a demised or vanished additional foetus.
  • The NIPT test is not suitable if you have cancer or chromosomal abnormalities including T21, T18 and T13.
  • The NIPT test is not suitable if you have received an organ transplant or have received stem cell therapy or immunotherapy in the last 12 months.
  • The NIPT test is not suitable if you have had a blood transfusion within the last 3 months.
  • The NIPT test is not suitable if you have a multiple pregnancy greater than twins.

Please Note

You must have had a previous scan within the NHS to have a NIPT without a scan, and you must bring the information you recieved along with you to your appointment at Yorkshire Baby Scan. We also accept previous scans from here at Yorkshire Baby Scan.
