For many pregnant women and their families, finding out the baby’s sex is one of the most exciting parts of pregnancy. Traditionally, parents had to wait until the second-trimester ultrasound to get a glimpse of their baby’s sex chromosomes. But with modern advances in Non-Invasive Prenatal Testing (NIPT), it’s now possible to learn much earlier: and with remarkable accuracy.
Early Reveal specializes in providing early, reliable answers through safe and advanced blood tests that use maternal blood samples. But how accurate is the NIPT gender test, and how does it compare to methods like ultrasound examinations or invasive testing such as amniocentesis or chorionic villus sampling (CVS)? Let’s break it down.
What Is NIPT and How Does It Reveal Baby’s Sex?
NIPT (Non-Invasive Prenatal Testing) is a genetic screening method that analyzes cell-free fetal DNA (cffDNA) circulating in the mother’s bloodstream. During pregnancy, fragments of the baby’s genetic material pass through the placenta into the mother’s blood. By examining these DNA fragments, laboratories can detect the presence or absence of the Y chromosome.
- If Y chromosomes are present → the baby is male.
- If no Y chromosome is detected → the baby is female.
Beyond identifying the baby’s sex, NIPT is also used to screen for chromosomal conditions and genetic abnormalities, including:
- Down syndrome (Trisomy 21)
- Edwards syndrome (Trisomy 18)
- Patau syndrome (Trisomy 13)
- Turner syndrome
- Klinefelter syndrome
- Certain microdeletions and other chromosomal disorders
Because NIPT relies only on a blood sample from the mother, it avoids the risks associated with invasive tests like amniocentesis or CVS, which involve collecting amniotic fluid or placental tissue and carry a small risk of miscarriage.
When Can Pregnant Women Find Out Baby’s Gender with NIPT?
One of the biggest advantages of NIPT is how early it can determine fetal sex. While an ultrasound typically provides reliable gender information between 16–20 weeks of gestation, NIPT can often reveal the baby’s sex as early as 7–10 weeks.
At Early Reveal, we offer gender determination testing as soon as 7 weeks into pregnancy, giving moms and families a head start compared to waiting months for an ultrasound examination. For parents eager to plan ahead—whether for bonding, nursery preparation, or gender reveal celebrations—NIPT is a safe and accurate choice.
Find Out Your Baby’s Gender Sooner
Why wait until 16–20 weeks for an ultrasound? With Early Reveal, you can learn your baby’s gender as early as 7 weeks—safe, accurate, and stress-free. Start your journey with confidence today.

How Accurate Is the NIPT Gender Test Compared to Ultrasound and Invasive Tests?
When it comes to gender determination, accuracy matters. Research consistently shows that NIPT has an accuracy rate of over 99% for detecting a baby’s sex. Some providers, including Early Reveal, report gender accuracy as high as 99.9% thanks to advanced analysis of cell-free DNA.
By comparison:
- Ultrasound: accuracy increases later in pregnancy but can be limited by factors like fetal position or the clarity of the scan.
- Amniocentesis and chorionic villus sampling: nearly 100% accurate, but invasive and carry a small risk of miscarriage.
NIPT therefore offers the best balance: it combines high sensitivity and specificity with the safety of a simple blood test.

Factors That Can Affect NIPT Gender Accuracy
Although highly reliable, NIPT gender testing can be influenced by certain biological and technical factors:
- Low fetal fraction: testing too early may not provide enough fetal DNA for accurate analysis.
- Maternal BMI: higher BMI can dilute fetal DNA, making detection harder.
- Vanishing twin: leftover DNA fragments may affect results.
- Chromosome abnormalities or genetic conditions: rare disorders like mosaicism can complicate interpretation.
- Sample handling: as with any genetic testing, lab quality control is critical for accuracy.
What Happens If NIPT Results Don’t Match Ultrasound or Prenatal Diagnosis?
In rare cases, results from an NIPT gender test may differ from later ultrasound findings. When discrepancies occur, doctors may recommend confirmatory steps:
- A detailed anatomy scan at 18–22 weeks.
- Diagnostic procedures such as amniocentesis or CVS, if medically necessary.
While NIPT is extremely accurate, it remains a screening test rather than a diagnostic one, so confirmatory testing is sometimes advised in cases of conflicting information or suspected chromosomal abnormalities.
