DNA Gender Test vs Ultrasound Gender Scans

How do DNA gender tests work?

A DNA gender test is a blood test. From as early as 6 weeks pregnant, a lab checks a small sample of mum's blood for tiny traces of your baby's DNA. If male DNA shows up, it's a boy; if not, it's a girl. The SneakPeek test we used to offer through Gateway Genomics reported 99.9% accuracy when the sample was collected correctly.

That early answer was the big appeal — and we loved offering it. But it meant a needle, a posted sample, and a wait of several days for the lab result. And the accuracy depended on a clean sample: any mix-up in collection could skew the result.

How does ultrasound gender determination work from 14 weeks?

From 14 weeks, our sonographer looks directly at your baby on the ultrasound screen and checks the anatomy between the legs. There's no needle and no lab — you lie back, watch your baby wriggle, and get the answer during the scan. Gender scans at Baby Bump Ultrasound start from $90.

One honest catch: bub has to cooperate. Some babies cross their legs or curl up at exactly the wrong moment. That's why we have our promise — if bub hides the goods on the day, you come back for another go. Free.

Which is more accurate — a DNA gender test or an ultrasound?

Honestly? The blood test wins on paper. A lab-run DNA gender test is about 99.9% accurate from 6 weeks, when the sample is collected properly. Ultrasound gender determination at 14+ weeks is very reliable in experienced hands, but it depends on baby's position and how clearly the anatomy shows on the day.

So no, we won't pretend ultrasound beats a lab. What it gives you instead:

• An answer you can see — not a line on a report, but your actual baby on the screen.
• No blood draw, no postage, no lab queue — the answer arrives during your appointment.
• A free return visit if bub won't show us on the day.
• A moment you can share — bring your partner, the grandparents, the big kids.

Can I still get a SneakPeek test in Australia?

No — SneakPeek no longer operates in Australia, so the test isn't something we or anyone else here can order in for you. We've put our energy into what we do best instead: scanning. Everything now happens in one visit, in our Upper Coomera studio, with our sonographers — no lab in the middle, no waiting by the letterbox for a result.

It also means finding out the gender feels like an occasion, not a test result. Mums tell us that seeing the answer on screen beats any email — you can read their words on our reviews page.
