In landmark research involving over 1,000 pregnant women, and our largest clinical study to date, SneakPeek Early Gender DNA Test was found to be over 99% accurate1.
Prior to modern methods of gender prediction like a Sneakpeek early gender test, the ultrasound was the only way a pregnant woman could determine the gender of her unborn baby. Now, early gender test methods are available to moms around the world, but many people still wonder about gender blood test accuracy. So, how accurate is the Sneakpeek early gender test?
SneakPeek’s Clinical Study & How It Was Run
Between October through December 2019, venipuncture blood samples were collected from women who were between 7-37 weeks into pregnancy, with the median gestational age being 10 weeks. The SneakPeek Early Gender DNA test was run to determine and provide the fetal sex of the babies. When the babies were born, SneakPeek surveyed the participants to learn if the birth gender of the baby matched the test result that SneakPeek provided. This screening method ensured that the most accurate method of determining baby’s true sex was used – the baby’s sex at birth.
Our Gender Blood Test Accuracy: The Results
Of the 1,029 samples, SneakPeek test results matched the baby’s birth gender with over 99% accuracy1. Baby boys were correctly identified in 505 of 506 samples and baby girls were correctly identified in all 523 samples. There were no cases of male DNA contamination in this study (i.e. no false positives).
Sneakpeek’s previous 2019 study concluded our gender determination test demonstrated 99.1% effectiveness, which means that predicting baby’s gender with Sneakpeek is more accurate than ever. Moreover, Sneakpeek enables parents to accurately learn baby’s gender weeks earlier than the typical non-invasive prenatal test (NIPT) and months earlier than the standard 20-week ultrasound.
Why You Should Rely on a Sneakpeek Early Gender Test
Compared to other options, the Sneakpeek gender prediction test is more affordable and accurate. Through a simple at home blood sample, you can learn the baby’s gender more quickly than:
- Urine tests: Unlike a urine pregnancy test, urine gender tests have no scientific basis and have not proven an accurate form of fetal sex determination.
- 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, an anatomy scan that identifies fetal sex is rarely performed before 18-20 weeks into pregnancy.
Are Baby Gender Test Kits The Same As Those at The Doctor’s Office?
SneakPeek’s early gender test is not the same test that is offered at your provider’s office. Your provider will usually perform a test that is known as noninvasive prenatal testing (NIPT). This test screens for down syndrome and other chromosomal conditions, not fetal sex identification. NIPT will scan for fetal DNA that is moving in the mom’s bloodstream. Women with high and even low risk of having a baby with chromosomal abnormalities will be offered a NIPT.
At-home fetal DNA tests require a small maternal blood sample. According to Healthline, the cell-free DNA test will only determine if there is an absence or presence of the male Y chromosome in the mom’s blood to determine the fetal gender. This DNA gender blood test will not be able to determine if your baby had any detected chromosomal abnormalities like the NIPT would.
