Check out SneakPeek Gender Test to find out your baby’s gender as early as 6 weeks with over 99% accuracy!
The SneakPeek® Early Gender DNA Test is one of the most popular early gender prediction tests available in the United States today. While the SneakPeek Test boasts a remarkable track record, predicting a baby’s sex with over 99% accuracy before traditional ultrasounds, other brands make similar claims.
So when it comes down to it, how does the SneakPeek test measure up with its competitors?
Accuracy aside, your satisfaction with any product you buy also comes down to process, experience, and price.
Whether you’re team SneakPeek Test or still researching your options, this article is meant to provide a fair and honest comparison of SneakPeek vs. competitors so that you can make the most informed decision about learning your baby’s predicted sex.
How at-home gender tests predict a baby’s sex
At-home DNA testing to predict a baby’s sex works by analyzing fetal DNA found in a pregnant person’s collected blood sample. This is known as cell-free DNA (cfDNA), which can be detectable as early as 6 weeks into a pregnancy.
By screening for Y chromosomes in cfDNA, at-home gender prediction tests can tell whether a baby is likely to be a boy (as males have one X chromosome and one Y chromosome; on the other hand, females have two X chromosomes and no Y chromosomes). If a test finds no traces of a Y chromosome, it’s assumed (by deductive reasoning) that a baby will be a girl.
Given this process of detection, early at-home prediction tests are extremely sensitive. They require careful handling and lab analysis for accurate test results.
When it comes to the SneakPeek Test, the unique methodology is backed by clinical studies, as well as popular approval: it’s a favorite among parents, and the #1 OBGYN-recommended at-home sex prediction test on the market today.*

SneakPeek vs competitors: key differences
If you’re still weighing your options when it comes to early sex prediction tests, it’s helpful to consider several factors that may impact your experience with your chosen product.
Testing method options
Many tests offer several distinct vehicles for collecting your sample. The SneakPeek Test uses an arm-based testing method that’s virtually pain-free. Some other brands also offer a lancet or finger-prick method.
Many expecting parents find that both of these options are:
- Simple
- Convenient
- Easy-to-use
However, the SneakPeek Test users enjoy a uniquely supportive experience, with a device that also allows for greater hygiene and comfort.
Contamination risk
Any test carries some risk of contamination by male DNA, which can throw off the results of early sex prediction tests. Risks of contamination are higher in households with multiple males or if a sample is handled by a male partner.
Every brand cautions product users about this risk and presents the option of taking the test in a clinical setting with a qualified provider. However, the SneakPeek Test and its accompanying accessories have been purposefully designed to minimize the chances of contamination if you choose to use it at home. Ample instructional content—both pamphlets and online videos—help make collection easier, more convenient, and more foolproof.
Price
Prices for early sex testing can vary depending on the method used and how quickly you want your results. The SneakPeek Test offers two different price points:
- SneakPeek Snap Standard – $99
- SneakPeek Snap FastTrack – $159
While select competitors’ tests come at a slightly lower price tag, the SneakPeek Test is still considered #1 by OBGYNs across the country, thanks to its accuracy, fast turnaround time, and excellent customer service—making the extra cost well worth it.
Clinical approval
Aside from being the top-recommended test by OBGYNs, nine published clinical studies endorse the SneakPeek Test as the premier early sex prediction test.
Availability
Many tests offer express shipping options. That said, other tests may have geographic limitations. For instance, one competitor requires residents of New York to use a non-New York address to order kits and ship samples. This is because the company is currently unable to process samples from New York.
Customer responsiveness
Customer reviews can tell you a lot about how products work once they’re out of their packaging and in the real world. But equally important is a company’s responsiveness—how they adapt, take accountability, and change their offerings to improve the customer experience.
As mentioned, any at-home early sex prediction test carries a risk of male DNA contamination, and thus faulty results. However, in response to this risk, the SneakPeek Test was redesigned to ensure accuracy as much as possible.
As Lenae H., an expecting parent who used the SneakPeek Test, puts it:
I was so thrilled and excited to try out the SneakPeek Snap…It is easy to use and the new technology provides for less chance of male DNA contamination!
From the beginning, our mission has been to set the standard in at-home early sex prediction testing for expecting parents. Switching up our offerings to improve the experience and lives of expecting parents is simply how we stay on target.
Selecting your test: how to choose which is right for you
Side-by-side comparisons of products can tell you a lot about what to expect from them. However, your satisfaction is also qualitative. With that in mind, it can help to ask yourself the following questions before making a decision:
- How important is test quality to you? – In comparison with competitors, the SneakPeek Test has an exceptional reputation among obstetricians and gynecologists, as well as clinical studies reviewing its accuracy.
- Would you prefer at-home or clinical testing? – While many companies offer the option to have their tests professionally administered, the availability of the SneakPeek Test covers slightly more geographic ground.
- Are you concerned about access? – If you’re interested in an at-home option, you’ll find the SneakPeek Test widely available at major retailers like CVS. You can also order the test online through the SneakPeek website or Amazon.
When it comes down to it, your sex testing process should be convenient, reliable, and affordable so that you can focus on what really matters—what to do before the baby comes!
