Gender Scans

baby03Gender Scans (sometimes called sexing scans) have been performed hundreds of thousands of times and remain the most popular in the UK. Our highly accurate* professional opinion is based on a dedicated protocol using 2D ultrasound to show parents the sex of their baby. Your choice of a free rescan is included if your baby’s position is not favourable on the day for the primary purpose of this scan.

All scans are performed by a qualified Sonographer with obstetric ultrasound scanning experience.

*Please note ultrasound alone can never provide a 100% guarantee of the sex of your baby.

Before Your Scan

When you book your appointment we will confirm some details, like how far along your pregnancy you are. Depending on your gestation and scan type it may be necessary to attend with a full bladder. Please aim to arrive 5 minutes prior to your scheduled appointment so that we can get your paperwork out of the way, and maximise the time you can spend with your baby.

What Your Visit Involves

Once you are in the scanning room you will be able to see exactly what our sonographer is viewing as we have installed a large wall mounted screen for you and your family to watch your baby in real time. Once we have obtained images of your baby you will then be able to choose which images you would like to take home with you.

Extra Prints

Speak to us on the day before your scan starts if you would like additional prints.


Scan Terms & Conditions

Please read our Scan Terms & Conditions below, you will be asked to sign to say you agree with them when you arrive for your scan.

1. I confirm that I am/will be receiving antenatal care and that I will discuss any of my scan finding with my medical team.
2. All scans are dependent on the baby’s position and maternal habitus. High BMI ratios significantly reduce the likelihood of achieving satisfactory images. If your baby is in a sub-optimal position to obtain the required views, a repeat scan may be offered at the sonographer’s discretion.
3. Preview Baby Limited’s range of scans are to encourage parental bonding and enhance the pregnancy experience, with research suggesting that there are both psychological and other health benefits to be gained from prenatal scans. All of the scans performed at Preview Baby will assess basic fetal wellbeing, however it should be noted that performing an in depth anatomy check is not the sole purpose of most scans we offer.
4. As per national standards, not all abnormalities can be detected and excluded through ultrasound scanning. A list of expected detection rates of abnormalities can be found at Preview Baby will not be held responsible if an abnormality goes undetected. If an abnormality is identified/suspected during the scan, the findings will be detailed in the scan report, where a scan report is provided. It is your responsibility to ensure this information has been passed on to your maternity unit/relevant healthcare professional.
5. Please indicate to the sonographer if you wish to know the sex of your baby. Please be aware that it is not always possible to determine the sex of your baby if it is in an unsuitable position. Ultrasound cannot 100% guarantee the sex of your baby and the information given about the gender of your baby is based on a professional opinion.
6. If you do not wish to know the sex of your baby, please let the sonographer know and every effort will be taken to try and conceal the sex of the baby from you. It should however be noted that during detailed ultrasound scanning it may be possible for you to discover the sex of your baby. Preview Baby Limited does not accept liability if you discover the gender of your baby during a scan that is not specifically intended to reveal the gender.
7. All scans are performed by fully qualified and accredited health professionals using equipment in accordance with manufacturer guidelines. Ultrasound is widely recognised as a useful tool when used prudently by qualified professionals. There is no evidence to date that diagnostic ultrasound has produced harm to patients since its first use in the mid 1950’s.
8. Any children you bring must be supervised at all times and remain your sole responsibility.
