Noninvasive Prenatal Testing (NIPT)
Thursday 29th June 2023
Noninvasive Prenatal Testing (NIPT) is a revolutionary advancement in the field of obstetrics
and gynaecology. This test is a game-changer as it enables doctors to detect chromosomal
abnormalities in the foetus as early as ten weeks of pregnancy. In this informative article, we will
discuss all you need to know about NIPT testing, including its benefits, limitations, and how it
works.
What Is NIPT Test?
NIPT is a screening test that analyses the cell-free DNA (cfDNA) in the maternal blood. This test
is noninvasive, meaning it does not require a needle to be inserted into the uterus, unlike other
diagnostic tests such as amniocentesis and chorionic villus sampling (CVS). With a high degree
of accuracy, NIPT can detect chromosomal abnormalities such as Down syndrome, Patau
syndrome, Edwards syndrome, and Turner syndrome.
How Does NIPT Work?
NIPT is a simple blood test that can be performed as early as ten weeks of pregnancy. During
pregnancy, the placenta releases cfDNA into the maternal bloodstream. This cfDNA contains
genetic material from the foetus, which can be analysed to detect chromosomal abnormalities.
NIPT uses advanced sequencing technology to analyse the cfDNA and identify any genetic
abnormalities. The results of the test are usually available within seven to ten days.
Benefits of NIPT Test
NIPT has several benefits over other diagnostic tests such as amniocentesis and CVS:
● NIPT is noninvasive, which means that it does not carry a risk of miscarriage.
● NIPT can be performed earlier in pregnancy than other diagnostic tests, allowing for
earlier chromosomal abnormalities detection.
● NIPT has a higher degree of accuracy than other screening tests such as the nuchal
translucency (NT) scan.
Limitations of NIPT Test
NIPT is a screening test, meaning it cannot diagnose chromosomal abnormalities with 100%
accuracy. False positive and false negative results can occur, although this risk is low. In cases
where NIPT returns a positive result, further diagnostic tests such as amniocentesis or CVS
may be required to confirm the diagnosis.
Who Should Consider NIPT Testing?
NIPT testing is recommended for women who have a high risk of having a child with a
chromosomal abnormality. This includes women who are over the age of 35, have a family
history of chromosomal abnormalities, or previously had a child with a chromosomal
abnormality. NIPT testing may also be recommended for women who have received abnormal
results from other screening tests, such as the NT scan.
Cost of NIPT Test
The cost of NIPT testing varies depending on the provider and the location. In the UK, NIPT
testing is available on the NHS for women considered to be at high risk of having a child with a
chromosomal abnormality. For women who do not qualify for NHS-funded testing, NIPT testing
is available privately and costs £400 at Numi Scan.
Conclusion
NIPT testing is a significant advancement in prenatal care, providing early detection of
chromosomal abnormalities with high accuracy. While NIPT testing is not a diagnostic test, it
can provide valuable information that can help women make informed decisions about their
pregnancy. If you are considering NIPT testing, speak to your doctor or midwife to see if it is
right for you.
