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.
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.
Since it does not require direct intervention to the baby, it is non-invasive and therefore different from procedures such as amniocentesis.
Important note: NIPT is a screening test; it is not a definitive diagnostic test.
The NIPT test can usually be performed starting from the 10th week of pregnancy. After this period, a sufficient amount of fetal DNA is expected to be present in the mother's blood.
A simple blood draw from the mother is sufficient for the test. No special preparation or fasting is required.
It is performed during pregnancy to help assess the baby's risk for certain chromosomal and genetic conditions early and reliably.
Down syndrome is a genetic difference that occurs when there is an extra copy of chromosome 21 in the baby's cells (Trisomy 21).
It is the most common type and can be screened with high accuracy using the NIPT test.
Although they are used for the same purpose, their working principles and accuracy rates are quite different.
No, NIPT tests differ from one another. Scope, technology, laboratory quality, and test failure rate may vary.
The diseases the test can screen for and scientific performance data such as PPV/NPV are important.
The analysis method and algorithms affect the reliability of the test even at low fetal DNA rates.
The "no-result" situation due to reasons such as low fetal DNA. Tests with low failure rates should be preferred.
ISO standards and the provision of expert genetic counseling support, especially in suspicious cases, are critical.

| 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. |
Note: This scoring does not replace clinical decision-making; it is an informative comparison prepared according to the scope and published performance data of the tests. The data has been evaluated using artificial intelligence.

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.
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.
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.

Since there is no direct intervention to the baby, it is non-invasive and different from amniocentesis.

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
