What is the accuracy of the nipt for sex? 2025 tests, evaluated

Congratulations! You have a baby, and with it comes a whirlwind of emotions, appointments and great stages. Among the most anticipated? Find out if you have a boy or a girl. For many future parents, the non -invasive prenatal test (NIP) does not only offer an overview of baby’s health, but also the answer to the secular question: Is it a boy or a girl?

So, to what extent is a NPT test precise for sex? Here is everything you need to know.

What is a Nipt test and how does it work?

Nipt means non -invasive prenatal tests. It is a blood test which analyzes small fragments of fetal DNA circulating in the blood of the pregnant person. Initially designed to detect chromosomal conditions such as Down syndrome, Edwards syndrome and Patau syndrome, NIP is now widely used to detect fetal sex with great precision.

The test is generally offered from 10 weeks of pregnancy and requires a simple blood sample. Because it uses fetal DNA without a cell, it is not invasive and poses no risk for the baby.

What is the accuracy of the nipt for sex?

In most cases, Nipt is more than 99% precise When determining fetal sex – especially after the 10 -week brand. Nipta Panorama of Natera is widely used in the United States, for example, And known for its reliable fetal sex detection, with a precision rate above 99%.

However, each laboratory can vary slightly, so always check with your supplier. The test works by detecting the presence (or absence) of chromosomes y in the blood sample:

• If the chromosomes are detected, you probably have a boy.
  
• If no chromosomes is present, you probably have a girl.
  

It is important to note that although precision is raised, Nipt is technically a screening test – Not diagnostic. Factors such as fetal fraction (how much fetal DNA is present in your blood), gestational age and even laboratory practices can have an impact on results.

Current questions about the precision of the genus nipt

Now decompose some of the most common questions that parents have on the precision of the sexes of the Nipt.

What is the accuracy of the Nipt for Sex at 11, 12 and even 10 weeks?

Most suppliers recommend waiting up to 10 weeks for optimal precision. At this stage, there is generally enough fetal DNA in the blood circulation to provide very reliable results. Studies suggest an accuracy of more than 99% from 10 weeks.

At 11 weeks, the fetal fraction continues to increase, which means that precision remains high – still oscillating above 99%. Jumping at 12 weeks, the results are generally as precise as possible. Precision at this stage is often considered equally with ultrasound in the second quarter.

What is the precision of the Nipt blood test for the genre as a whole?

Overall, the NPT is among the most precise non -invasive methods to determine fetal sex. According to This studyPrecision can exceed 99%, especially in Singleton pregnancies.
