Quick comparison: The SneakPeek® Test vs. NIPT

At a glance, the following features distinguish the SneakPeek® Early Gender Test from NIPTs/cell-free DNA (cfDNA) screens:

Each method is designed for a distinct purpose and timeline. Both tests use blood samples, but the experience they offer is different.

Understanding the core differences between the SneakPeek® Test and NIPT

The main differences between the SneakPeek® Early Gender Test and an NIPT come down to purpose and timing:

• The SneakPeek® Early Gender Test is specifically designed to identify a developing baby’s predicted sex. It can be used very early, as soon as 6 weeks into pregnancy, and is intended for parents who want early insight without having to book an appointment with their healthcare provider.

Importantly, the SneakPeek® Test is meant to be a complement to, not a replacement of, prenatal care. In other words, the results are later confirmed by an ultrasound or NIPT in a clinical setting.

• NIPTs are a medical screening tool generally offered to expecting parents at 10 weeks of gestation (although some can be done as early as 8 weeks). Their main purpose is to screen for chromosomal conditions. However, because they look at chromosomes, they can also identify a baby’s predicted sex (as sex is most often determined by chromosomes).

NIPTs and the SneakPeek Test® have unique purposes, which is why the timing, setting, and experience of each is different. While the SneakPeek Test® focuses on sex, NIPTs are part of a broader prenatal screening process administered by a healthcare provider.

Understanding this distinction helps to reframe the comparison, as neither test is “better” than the other. They simply serve different purposes.

6 benefits of taking the SneakPeek® Early Gender Test

For parents who are focused on discovering their baby’s predicted sex, the SneakPeek Test® offers several unique advantages. These stem from how the test was designed to support a real-world pregnancy experience.

#1 Earlier testing window

One of the most distinctive advantages of the SneakPeek Test® is timing: Expecting parents can learn their baby’s predicted sex as early as six weeks into pregnancy—around 2-4 weeks earlier than a cfDNA screen.

If you’re a parent who can’t wait to know more about your future baby and want information sooner rather than later, this early testing window can mean a lot. You and your family can discover your child’s predicted sex in your first trimester, rather than waiting several more weeks.

#2 At-home convenience

The SneakPeek® Test is designed for convenient home use. For parents who want to simplify their reveal experience, this means:

• No need to book an appointment
• No need to spend time in a waiting room
• No need to schedule around childcare, work, or other obligations

Whether you’re incredibly busy or live a long way from a clinic, the SneakPeek® Test makes it possible to learn your baby’s predicted sex on your schedule. It’s reliable, giving parents confidence while waiting for results back.

#3 Focused purpose

The SneakPeek® Test was created exclusively to help parents determine their baby’s sex. Unlike NIPTs, it does not screen for chromosomal or health-related medical conditions.

For many parents, this focus is a plus, allowing them to take their baby’s development step by step. They can get the information they’re looking for—their future child’s sex—without having to field or interpret medical information they may not be ready to think about yet. This helps parents come back to the information that matters most to them.

#4 Over 99% accuracy when used as directed

When the SneakPeek® Test is used as directed, it delivers results with over 99% accuracy. How?

A laboratory technician reviews the test sample to screen for the presence of a Y chromosome, which indicates whether a baby will likely be a boy or a girl.

That said, users must follow the kit’s instructions to collect their sample carefully. This will ensure the highest probability of accurate lab results.

#5 No insurance or clinical gatekeeping

Though most insurance plans contribute to NIPT expenses, the cost of an NIPT varies depending on your company, plan, and coverage. Conversely, the SneakPeek® Test is widely available online and in-person at pharmacies, with no requirements for:

• A provider referral
• Insurance approval
• Insurance coverage verification

Plus, the SneakPeek® Test offers options at $79 and $159, making it an accessible and affordable option for many expecting parents.

#6 Complements (doesn’t replace) prenatal care

As mentioned, the SneakPeek® Test is intended to be used as a complement to, not a replacement of, prenatal care. Many parents use the test in the very earliest weeks of pregnancy. Then, the results are later confirmed by an ultrasound or NIPT.

In this way, the SneakPeek® Test empowers parents with information earlier, while still fitting into a comprehensive prenatal care protocol.

The benefits of NIPT

The SneakPeek® Test offers clear, meaningful benefits for parents eager to learn about their baby’s sex sooner. However, the American College of Obstetricians and Gynecologists still recommends chromosomal screening for all pregnancies.

Additionally, parents may prioritize NIPTs over the SneakPeek® Test when:

• Prenatal screening is a primary goal – NIPTs are designed to screen for chromosomal conditions, offering genetic insights beyond a baby’s sex.
• The test is already scheduled through a healthcare provider – Many parents are offered NIPTs as a part of routine prenatal care, making it a convenient option if you’ve already discussed and scheduled one with your healthcare provider.
• They prefer to have all testing handled clinically – Some families feel most comfortable getting tested and test results directly from their healthcare provider—and that’s perfectly okay.

FAQs: Addressing common questions parents have when comparing tests

Expecting parents often share similar questions when learning about NIPTs and the SneakPeek® Test. Below, we’ll answer some of the most common questions to provide even greater clarity.

Is the SneakPeek® Test as accurate as NIPT for determining a baby’s sex?

According to nine peer-reviewed, published studies, the SneakPeek® Early Gender Test is more than 99% accurate when used as directed. This makes it an ideal option for parents who want accurate information on their baby’s predicted sex in early pregnancy.

NIPTs are also highly accurate for sex determination. That said, they’re performed several weeks later in pregnancy.

Why would someone choose the SneakPeek® Test instead of NIPT?

Parents might choose only the SneakPeek® Test for several reasons:

• At-home convenience
• Early timing
• Prioritization of sex determination with no interest in medical information

These features work well for families who want to complement the excitement of early pregnancy with simple, straightforward insights about their future baby.

Can the SneakPeek® Test results be confirmed later?

Yes! Many parents use the SneakPeek® Test to learn about their baby’s sex early in pregnancy. Then, their findings are confirmed later by an anatomy scan, ultrasound, or NIPT.

For many parents, using multiple methods over the course of pregnancy can be emotionally reassuring and a practical way to reinforce milestones.

Does the SneakPeek® Test replace medical testing?

No. The SneakPeek® Test is designed to give parents insight—it is not intended to diagnose chromosomal conditions, replace genetic screenings, or be a substitute for prenatal care.

Remember, the ACOG stresses that genetic screening plays a crucial role in every prenatal care plan. Even if you use the SneakPeek® Test to find out your baby’s predicted sex, it’s important to work with your healthcare provider to create and adhere to a care plan that will ensure you and your baby are taken care of.

Complementing your prenatal care plan with the SneakPeek® Test

Comparing the SneakPeek® Test and NIPT can help clarify the differences between these two tests. Rather than competing, each of these methods serves a distinct purpose at different points in the pregnancy journey. Understanding these distinctions makes it easier to know when you can take each test and what answers you can expect.

Ultimately, there is no one-size-fits-all time to learn your baby’s predicted sex. For parents who value early timing, accuracy, and convenience, the SneakPeek® Early Gender Test can be a compelling option. Others might be just as happy waiting for their cfDNA screening to find out the sex of their baby.

At the end of the day, what matters most is an informed, confident, and supported pregnancy experience—one where you feel confident and supported every step of the way. And for our early planning parents, knowing the baby’s sex sooner can also help with planning a gender reveal party or preparing a gender reveal checklist.
