A scan helps confirm that you are far enough along for the test to be carried out accurately (you must be at least 6 weeks pregnant). If the test is done too early, there may not be enough fetal DNA in your blood sample, which could affect the result.
The scan also helps confirm pregnancy location, viability, gestation and whether you are expecting a single or multiple pregnancy.
You’re more than welcome to have this initial scan elsewhere. If you have already had a recent scan elsewhere, you can book the Early Gender Blood Test Only appointment. We will need to see a copy of your scan report confirming your gestation before the blood test is carried out.
During pregnancy, small amounts of the baby’s DNA circulate in your bloodstream. The test analyses your blood sample for the presence or absence of the male Y chromosome. If the Y chromosome is detected, the result indicates a boy. If no Y chromosome is detected, the result indicates a girl.
This is a non-invasive test with blood taken from your arm, and it poses no risk to you or your baby.
Results are usually emailed within 2–5 working days once your sample has been received and processed by the laboratory. Results may occasionally take slightly longer during busy periods, bank holidays or postal delays.
If a Y chromosome is detected, this indicates that at least one baby is a boy. If no Y chromosome is detected, this indicates girls. The test cannot identify the individual gender of each baby in non-identical multiple pregnancies.
No. Fetal DNA from previous pregnancies clears naturally from the bloodstream after pregnancy, so a previous boy pregnancy should not affect your result.
Please drink plenty of water before your appointment, as being well hydrated can make it easier to obtain a blood sample.
We recommend wearing loose or comfortable clothing so your arm can be accessed easily. Please let us know if you are taking blood-thinning medication or if you feel nervous about blood tests so we can support you.
