NIPT Tests (commonly referred to as the Down’s Syndrome Test or Harmony Test) are designed to provide expectant parents with the opportunity to identify the probable presence of Down’s Syndrome, Edwards’ Syndrome or Patau’s Syndrome, as well as indicating the possible sex of your baby (if requested), from just 10 weeks of pregnancy. You must still attend your 12 week scan & 20 week scan with the NHS.

Hey Baby 4D‘s Early Reassurance Scan (15 minute scan to identify the gestation of your pregnancy, the location of the pregnancy and enables you to see your baby’s heart beating) is included in this package.

You must still attend your 12 and 20 week scans with the NHS.

Preparing For Your Scan:

You can prepare for your early reassurance scan by ensuring that you are properly hydrated; we recommend that you drink plenty of water in the hour before your scan.

Please bring your pregnancy notes with you. We may not need them, but it is helpful if our qualified Sonographers need to refer to them at any stage during your early reassurance scan.

Additional images, digital downloads of your scan images and a variety of products are available at Hey Baby 4D Watford to purchase on the day.
