In past years, the only way pregnant women could determine the gender of their baby was through an ultrasound. However, with newer methods, you can take an early gender test as early as 8 weeks into pregnancy without having to go to ultrasound clinics. With early gender test methods, such as the SneakPeek gender prediction test, the accuracy of the results comes into question. So, how accurate is the gender blood test for gender with SneakPeek?
In a new study published by the International Journal of Pregnancy & Child Birth, researchers showed that the SneakPeek Early Gender DNA Test predicts a baby’s gender as early as 8 weeks into pregnancy with 99.1% accuracy. This means parents can now learn their baby’s gender weeks earlier than the typical non-invasive prenatal test (NIPT) and months earlier than the standard 20-week ultrasound.
The company’s previous 2017 study had demonstrated over 99% effectiveness at 9 weeks, and the new breakthrough study has shortened the waiting time by another week.
SneakPeek: The Only Early Gender DNA Blood Test
When you look closely at early gender prediction options, it turns out many are based on a urine test rather than a DNA blood test. Scientifically, there are no gender-related hormones in urine, so the tests are at best a coin toss, and at worst, a waste of money. Do more searching, and you’ll identify the main accurate gender test options for discovering baby’s gender:
- Non-invasive prenatal tests (NIPTs): This prenatal test is required to be ordered through a physician and only covered by insurance for high-risk pregnancies, NIPTs can cost as much as $1,000 out of pocket and are typically conducted between 10-12 weeks into pregnancy.
- Ultrasound: While doctor-ordered ultrasound scans are usually covered by insurance, anatomy scans that identify fetal sex are rarely performed before 18-20 weeks into pregnancy.
- SneakPeek: SneakPeek is the only early gender DNA blood test that you can take at home with 3 peer-reviewed, scientific publications identifying gender with over 99% accuracy. SneakPeek can be used beginning at 8 weeks into pregnancy, weeks to months earlier than any other available method.
Scientific Publication Showing SneakPeek is 99.1% Accurate at 8 Weeks
In this newly published study, researchers collected DNA blood samples from 108 pregnant women from 5 different ultrasound clinics whose babies were at 8 weeks average gestational age. The SneakPeek Early Baby Gender Blood Test looks for Y chromosomes, which are only found in male-bearing pregnancies. If a Y chromosome is found, the baby is classified as male. If a y chromosome is not found, the baby is classified as female. A SneakPeek test was run for all samples, and gender was correctly identified for 107 of the 108 samples, leading to a 99.1% gender blood test accuracy rate. See the full study below.
