NIPT (Non-Invasive Prenatal Screening Test) Screening Tests in Derby 

When you are pregnant, your blood contains fragments of your baby's DNA. NIPT analyses DNA in a sample of your blood to predict the risk of Down syndrome (Trisomy 21) and certain other genetic conditions.

In addition, NIPT testing can assess foetal sex which is optional (no additional cost).

NIPT does not screen for non-chromosome disorders, familial mutations, malformations, foetal growth or foetal viability.

NIPT Screening is available for any women with pregnancies of at least the 10-week gestation period. The test covers single and twin pregnancies, including those conceived naturally or by IVF using the patient's or a donor's egg.

In twin pregnancies the sex chromosomes (X and Y) analysis can determine foetal sex but not sex chromosome conditions, meaning this test is not suitable in cases of a vanishing twin. The sex of twins will be given as one single result. If male, one or both twins will be male. If female, both twins will be female.

Note that NIPT testing does not assess the risk for mosaicism, partial trisomies or translocations

1. Early Pregnancy Scan
2. Blood Test
3. Results In 2-5 Working Days (once the lab is in receipt of blood)

As early as 10 weeks the NIPT Test screens for the risk of 3 major syndromes:

1. Trisomy 21(Down syndrome)
2. 18 (Edward syndrome)
3. 13 (Patau syndrome)

The test result will give you a clear answer about the risk to your pregnancy of having any of the genetic conditions included in the test (see above). All results will be given to you by Numi Scan Derby, meanwhile, you should continue with your usual scan appointments.

The results from the test will be available within 5 business days and we will notify you as soon as we receive them by email.

If the NIPT test shows that there is a high risk that the foetus has trisomy 21, 18 or 13, it does not mean that the foetus definitely has one of these defects. If you want to be certain that the foetus has one of these defects then you should have a CVS or amnio test which is carried out in hospitals as it is an invasive procedure requiring sample cells from the placenta.

If the NIPT test shows that there is a low risk (less than 1 in 10,000) that the foetus has trisomy 21, 18 or 13 it is unlikely that the foetus has one of these defects.

The NIPT test does not cover physical abnormalities like heart or brain issues, spina bifida, or foetal growth. It's recommended to complement with NHS ultrasound scans at 11-13 and 20-22 weeks for foetal anatomy, and at 30-32 weeks if needed for growth assessment.

VeriSeq NIPT Solution V2 isn't validated for pregnancies involving more than two foetuses, foetal demise, mosaicism, partial chromosome aneuploidy, triploidy, translocations, maternal aneuploidy, transplant, malignancy, or neural tube defects. Test accuracy might be affected by certain rare biological conditions.

A low probability outcome doesn't ensure a foetus is free from chromosomal or genetic conditions. Some non-aneuploid foetuses may yield high-probability results. Confirmatory testing is needed for diagnoses in cases of high probability results or other clinical indications of a chromosomal condition.
