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.

If you have not had a scan yet in this pregnancy, we recommend 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, as this test is accurate from at least 6 weeks and 0 days. Additionally, we will check for multiple pregnancies as they may affect your test results.

The Technology

A small fraction of fetal DNA circulates in the maternal bloodstream

A qPCR-based assay is used to detect cell-free fetal DNA from a micro-volume of maternal plasma

The Procedure
  • Please arrive 10 minutes before your appointment time. You will be welcomed at our clinic and asked to complete consent forms for the scan and for the genetic screening.
  • When ready, the sonographer will welcome you in the consultation room, confirm your details, the reason for your scan and discuss any particular concerns you may have.
  • If you opted to have a scan, the sonographer will perform a scan and will discuss with you what she / he are seeing.
  • When ready, the sonographer will then proceed, with your consent, to take a sample of your blood from your arm.
  • At the end of the appointment, you will be invited back to the reception room where you can collect your scan report.
  • You will receive your result within 5 to 7 business days of your blood draw via email directly from SneakPeek laboratory.
Results

The SneakPeek test detects either:

  1. Y-chromosome DNA: male fetus, or
