SneakPeek at 6 Weeks vs. Gender Ultrasound at 13+ Weeks: Which Is Right for You?
Finding out whether you’re having a boy or a girl can be one of the most exciting moments of pregnancy. Some parents want to know as early as possible, while others prefer to wait until they can actually see their baby during an ultrasound.
SneakPeek vs gender ultrasound
When comparing SneakPeek vs gender ultrasound, the biggest differences are how early you can find out and the type of experience you want.

At True Ultrasound in Lake Forest, Orange County, families have two early gender options: SneakPeek Early Gender DNA Testing beginning at 6 weeks and an elective gender ultrasound beginning at 13+ weeks.
So, which one is right for you? Here’s an easy comparison.
How Early Can You Find Out Baby’s Gender?
If you want to know as early as possible, a blood-based early gender test gives you an earlier option than ultrasound.
SneakPeek Early Gender DNA Testing can be used starting at 6 weeks of pregnancy. SneakPeek states that its test analyzes fetal DNA found in the pregnant parent’s blood to predict fetal sex.
If you prefer to find out while actually seeing your baby, True Ultrasound offers gender ultrasound beginning at 13+ weeks, when gender may be visualized depending on the baby’s position and development.
What Is SneakPeek Early Gender DNA Testing?
SneakPeek is a blood-based test designed for parents who want to find out early.
During pregnancy, small amounts of fetal DNA are present in the pregnant parent’s bloodstream. SneakPeek looks for male chromosomes in the blood sample to predict whether the baby is male or female.
At True Ultrasound, SneakPeek is a great choice if you:
Want to find out starting at 6 weeks
Don’t want to wait until an ultrasound can show gender
Are planning an early gender reveal
Want the option of next-day or 2-day results
Prefer an in-studio or in-home experience
SneakPeek currently states that its Early Gender Test is over 99% accurate starting at 6 weeks.
What Is a Gender Ultrasound?
A gender ultrasound is a completely different experience.
Instead of using a blood sample, you get to see your baby on the ultrasound screen while we look for the baby's gender.
At True Ultrasound, elective gender ultrasound is available starting at 13+ weeks.
Many families choose this option because they want the excitement of seeing baby move, sharing the appointment with loved ones, and finding out together.
Because every baby has their own position during an ultrasound, sometimes the view we need is simply not available.
If we cannot confidently determine gender during a 13-week gender ultrasound, True Ultrasound offers a complimentary rescan.

Can I Keep Baby’s Gender a Surprise?
Absolutely.
You do not have to find out during your appointment.
Many parents ask us to keep the result private so they can open it later together or share it with the person planning their gender reveal party.
If you are having an ultrasound, just tell us before we begin that you would like the gender kept secret.
We can make the experience as simple and private as you would like.
Can I Do My Gender Test or Ultrasound at Home?
Yes.
True Ultrasound offers both in-home SneakPeek Early Gender Testing and in-home gender ultrasound services throughout Orange County.
This can be a beautiful option if you prefer the privacy of home, want family members present, or are planning a gender reveal or baby shower.
Which Option Should I Choose?
The best choice depends on the experience you want.
If your biggest priority is finding out as early as possible, SneakPeek beginning at 6 weeks may be the better fit.
If you would rather wait a little longer and enjoy the experience of seeing your baby while finding out, a gender ultrasound beginning at 13+ weeks may be perfect.
And some families choose both: SneakPeek early in pregnancy and an ultrasound later for another special bonding moment.
