Our SneakPeek early gender test is a simple blood test that confirms the sex of your baby from as early as 6 weeks’ gestation. It uses the same technology as NIPT testing, whereby foetal DNA from the mother’s blood sample is analysed and the presence of the male chromosome (Y) is either found to be present or not present.

Key Information About Your SneakPeek Clinical Gender Test:

  • 15 minute appointment where our experienced phlebotomist will take a maternal blood sample
  • Please note that you must be at least 6 weeks pregnant for the test to be effective
  • The price of £129 does not include a dating scan
  • Results direct to your email within 5-7 working days (please note this may be longer during times of peak demand, such as Christmas)


Upgrade To Include Dating Scan For £50 (Recommended):

Hey Baby 4D highly recommends having a dating scan ahead of the test. This is to ensure that your pregnancy is viable, and to confirm the gestation of your pregnancy. Additionally, we will check for multiple pregnancies – all of these things can affect your test results.

    Please Note:

    • We are only able to provide services to customers over the age of 18
    • If you opt for a test without a scan, there is a chance that your pregnancy may be at a different stage to what you expect, or that the pregnancy is not viable. Hey Baby 4D therefore advises that a dating scan be performed ahead of the blood sample being taken
    • The video recording has no audio capability
    • We have male and female sonographers working in our clinic. A chaperone service is available free of charge – please let us know if you’d like one when you arrive for your appointment
    • In the event you test positive for Covid-19, please do not attend your scan and call us on 020 3475 9000 to re-arrange your appointment

      Frequently Asked Questions

      How Does SneakPeek Work?

      While every person has her own DNA in her bloodstream, a pregnant woman’s bloodstream also contains DNA from her unborn child. SneakPeek looks for male chromosomes in a small sample of your blood. If male chromosomes are found, that means baby is a boy. If none are found, baby is a girl. SneakPeek is accurate at 6 weeks into pregnancy.

      What Is The SneakPeek Process?

      At SneakPeek Labs, a test process called non-invasive prenatal testing (NIPT) is used to analyze cell-free fetal DNA. Starting with a small sample of your blood, plasma is separated from whole blood by centrifuge, and extracted cell-free fetal DNA (cffDNA) is analyzed for Y chromosomes, which are found only in males. The SneakPeek test is sensitive enough to find even a single Y chromosome, giving you confidence in your results.

      I’ve previously had a boy. Will that skew my results? Clinical studies have shown that fetal DNA clears from mum’s bloodstream between a few hours to 2 days after birth.

      I’m having twins. Can SneakPeek determine fetal sex for each one? In the case of identical twins, if male DNA is found, then both babies are boys. If no male DNA is found, then both babies are girls. For fraternal twins (or more!), finding male DNA will confirm at least one baby is a boy, but cannot distinguish if the second is a boy or girl.

      Do hormone disorders such as PCOS affect my results? SneakPeek is a DNA-based test, so hormones do not impact results.

      Do blood thinners affect my results? SneakPeek looks only for the presence of Y chromosomes and is extremely sensitive and accurate. No blood thinners or other drugs are known to impact SneakPeek gender results.

      Is this test safe? SneakPeek Clinical is a non-invasive prenatal test (NIPT), and it’s safe for both mum and baby.

      How quickly can I get my results? You will receive your result within 5-7 business days of your blood draw.* Expect your result email between 4-8pm Pacific Time the day your sample is received by SneakPeek.

      Are results guaranteed? SneakPeek Clinical is the most accurate early gender test on the market. If your test result does not match the gender of your newborn, you’ll receive a full refund.

      How is my privacy protected? We know your DNA information is personal. To protect your privacy:

      1. SneakPeek tests only for baby’s gender. No data is gathered about disease states or other health-related information.

      2. After the test is run, your DNA sample is disposed of by a professional chemical management company in compliance with federal standards.

      3. SneakPeek never shares your results with anyone other than the email address you provide. Where can I learn more? Visit
