SneakPeek sells at-home early baby gender blood test kits that expecting parents can use from 6 weeks into pregnancy, with Standard lab processing or the prioritized FastTrack option.
Where the kit is bought matters for savings: the 30-day full refund on unused kits covers purchases made on SneakPeekTest.com, while kits from other retailers go back to that retailer.
SneakPeek was started by a pharmaceutical scientist who had worked on whole genome sequencing of fetal cells and kept hearing study participants ask about their baby's sex. The test was simplified to search for a single marker: if Y chromosome DNA shows up in the pregnant person's blood, the baby is predicted to be male, and if none is found, female. Because only one marker is needed, a small sample collected at home is enough. The founder's wife became its first tester.
The brand is based in San Diego, and its site lists Myriad Genetics as the owner of the SneakPeek trademarks. Beyond the at-home kit, the lineup includes a clinical version of the gender test, the Foresight Carrier Screen and the Prequel Prenatal Screen, and kits are also sold in stores. SneakPeek notes that its tests are for information and education, not diagnosis.

Accuracy guarantee
a full refund if the result does not match the sex on the state-certified birth certificate, requested within one year of birth.
Shelf life
kits stay good for 12 months, so one bought during a sale can wait until the right week of pregnancy.
APO/FPO/DPO addresses
served by USPS on the Standard option only, since FastTrack cannot go overnight to a military base.
A SneakPeek discount usually arrives by one of two routes: a friend's referral link, through which the friend gets $10 off the test kit, or a time-limited sale such as the $20 off announced as this week only.
The referral saving comes through the link itself, so opening that link before shopping is the step that matters.
Because a kit keeps for 12 months, a sale can be used even while the 6-week mark is still ahead.
Sezzle appears among the payment options.
Once results have been delivered a test cannot be returned, so any question about a missed discount belongs before the sample goes to the lab.
More ways to save at SneakPeek
Parents who have already tested can join the referral program themselves: each friend saves $10 through the link, and the referrer earns a 5% commission per order, paid monthly via PayPal.
Banner offers have promised savings of up to $30 on the SneakPeek Early Gender TeSt. The blood sample also travels back to the lab in a prepaid package.
SneakPeek questions, answered
How early in pregnancy can the SneakPeek kit be used?
The test works from 6 weeks into pregnancy, and an unopened kit stays good for 12 months, so it can be bought ahead of time.
What happens after an inconclusive SneakPeek result?
A retest is provided only for inconclusive results. An unused retest kit can be returned within 30 days of its ship date for a full refund of the original test.
How is the SneakPeek referral commission paid out?
Referrers earn 5% of each referred order, paid monthly through PayPal, while the referred friend gets $10 off the kit.
Can a SneakPeek kit bought from another retailer be refunded directly?
Kits bought at other retailers go back to the retailer that sold them. The 30-day full refund covers unused kits purchased on SneakPeekTest.com.
What if a clinical FastTrack result arrives late?
A clinical FastTrack result not emailed by 9pm Pacific on the expected day is converted to Standard processing with a $20 refund.
