NIFTY test
The NIFTY (Non-Invasive Foetal Trisomy Test) is a safe and easy foetal risk test provided by BGI to detect chromosomal abnormalities.
During pregnancy, a cell-free fragment of foetal DNA is released into the mother’s blood. Just over 5 ml of maternal venous blood is sufficient for NIFTY to test for foetal cell-free DNA.
The risk of foetal chromosomal abnormalities is calculated using next generation sequencing and bioinformatics analysis.
Which genetic abnormalities does the test examine?
- Trisomies: trisomy 21, 18, 13, 9, 16, 22
- Aneuploidy of sex chromosomes: X monosomy, XXY, XXX, XYY
- 84 deletion and duplication, l. 5p, 1p36, 2q33.1, 15q11.2, 11q23, 22q11.2, 16p12, 1q32.2
When is it recommended to have the NIFTY test performed?
The NIFTY test is recommended from the 10th week of pregnancy (but not limited to):
- The test is recommended for those who wish to avoid the risk of miscarriage following invasive prenatal testing
- Previous pregnancy with a chromosomal abnormality
- Screening for Down’s syndrome, which indicates an increased risk of abnormalities
- Pregnancy after artificial insemination or recurrent miscarriages
- In addition, the test is recommended for pregnant women who want a very accurate result as to whether their child has Down’s syndrome
Why should you have the NIFTY test?
- safe: non-invasive, no risk of miscarriage
- simple: the test can be performed on a small amount of blood
- early: it can be done as early as 10 weeks’ gestation
- fast: results in 9 working days
- accurate: proven to have a sensitivity of over 99% for trisomy 21, 18 and 13 (based on 147 000 pregnancies)
- reliable: more than 6 million tests performed worldwide
- comprehensive: detects abnormalities on all 23 chromosomes and screens for a further 96 different genetic abnormalities
When can I expect the result?
The result takes 12 days from the time the sample arrives at the laboratory.
