Next-Generation Genetic Screening

The Most Reliable Step
For Your Baby's Health

NIPT (Non-Invasive Prenatal Test) is an advanced prenatal screening test based on the examination of cell-free fetal DNA circulating in a blood sample taken from the mother during pregnancy.

Are NIPT Tests the Same? What Should Be Considered?

No, NIPT tests differ from one another. Scope, technology, laboratory quality, and test failure rate may vary.

Scope and Performance

The diseases the test can screen for and scientific performance data such as PPV/NPV are important.

Technology

The analysis method and algorithms affect the reliability of the test even at low fetal DNA rates.

Test Failure Rate

The "no-result" situation due to reasons such as low fetal DNA. Tests with low failure rates should be preferred.

Accreditation and Counseling

ISO standards and the provision of expert genetic counseling support, especially in suspicious cases, are critical.

9 Veragene 29.0 25.3 54.3 Although it offers certain additional scopes, test failure rate and data gaps limit the score.
10 Panorama 30.0 22.6 52.6 Although it offers scope in some specific areas, T13 and microdeletion PPV values lower the total performance score.
11 Veracity 25.0 25.3 50.3 Although basic performance data is available, test failure rate and limited scope affect the score.
12 RapidNIPT 30.0 10.0 40.0 It covers certain areas in terms of scope; however, the PPV/NPV data being N/A lowers the performance score.
13 NIPT 24 30.0 6.0 36.0 Although scope information is available, it receives a low score because scientific performance data has not been shared.
14 BabySec 30.0 0.0 30.0 Although scope information is available, no scientific performance score has been given because performance data is N/A.

What Do PPV and NPV Mean? Why Are They Important?

When interpreting NIPT results, knowing only the "positive" or "negative" result is not enough. It is also important to understand how reliable the result is.

PPV

Positive Predictive Value (PPV)

It is the probability that the baby actually has that condition when the test is positive.

So if the risk was high in the test, it shows how strongly this result actually supports the disease. PPV can vary according to the prevalence of the disease in the population and the risk level of the pregnancy.

NPV

Negative Predictive Value (NPV)

It is the probability that the baby actually does not have that condition when the test is negative.

So it shows how reassuring the result is in low-risk results.

Frequently Asked Questions

NIPT (Non-Invasive Prenatal Test) is an advanced screening test that analyzes cell-free fetal DNA in a blood sample taken from the mother. Since there is no direct intervention to the baby, it is non-invasive and different from amniocentesis. The test can be performed from the 10th week of pregnancy without requiring any special preparation or fasting. NIPT is a screening test; high-risk results must be confirmed with diagnostic tests.

Down syndrome is a genetic difference that occurs when there is an extra copy of chromosome 21 in the baby's cells (Trisomy 21). This condition can affect the baby's physical appearance, growth, and learning process, and can cause some health problems. Increased maternal age can increase the risk, but babies with Down syndrome can be seen in pregnancies of all ages. The NIPT test is a reliable screening method that can assess the risk of Down syndrome in the early stages of pregnancy with high accuracy. Learn more

Yes, NIPT tests differ from each other; they vary in terms of scope, technology, laboratory quality, and clinical performance. When choosing a test, attention should be paid not only to its name but also to the reliability of its content. Since the analysis methods and clinical performance data of the tests vary from laboratory to laboratory, how reliable they are for which conditions should be evaluated. Learn more

To understand how reliable NIPT results are, it is important to look not only at the positive/negative result but also at the PPV and NPV values. PPV (Positive Predictive Value) indicates the probability that the baby actually has the disease when the test is positive. NPV (Negative Predictive Value) indicates the probability that the baby actually does not have the disease when the test is negative. Learn more

NIPT tests are offered at different levels depending on their scope. Basic NIPT mainly focuses on Trisomy 21, 18, and 13 conditions. Extended NIPT covers sex chromosome abnormalities and some additional evaluations in addition to basic trisomies. Advanced comprehensive NIPT can offer much broader screening options such as microdeletion syndromes, deletions/duplications, rare autosomal aneuploidies, and some hereditary diseases. Learn more

Although both are screening tests that assess the risk of chromosomal diseases in pregnancy, their working methods are different. NIPT offers a much more sensitive, targeted, and highly accurate evaluation by directly examining the cell-free fetal DNA in the mother's blood. Conventional screening tests, on the other hand, are based on biochemical markers and ultrasound findings, and their accuracy rates are lower. Learn more

NIPT is performed to safely and early evaluate the risk of the baby carrying certain genetic and chromosomal diseases during pregnancy. The fact that the procedure is performed only with blood taken from the mother, and that it is non-invasive, meaning it does not cause any harm to the baby, is one of the most important reasons for preference. It has a high accuracy rate, especially in Trisomy 21, 18, and 13 diseases. Learn more
