  • Screening for trisomy 21 (Downs syndrome), trisomy 18 (Edwards syndrome) and trisomy 13 (Patau syndrome)
  • Very accurate in early prediction of the baby sex (optional - by request)
  • We have carefully selected Harmony Test from all other NIPT London providers
  • Can be done from 10 weeks of pregnancy
  • Performed together with the ultrasound scan at the same appointment
  • Not able to check baby's physical health and to exclude structural anomalies
  • Harmony Test results time in London is about 3-5 working days
  • In 3% of cases there are no-call results

What can be checked at Viability Scan?

  • Position of the pregnancy sac in the womb
  • Viability of the baby by presence of the fetal heart beat
  • Number of fetuses and type of twins or triplets in the case of multiple pregnancy
  • Gestational age and estimated date of delivery (EDD) by measurement of crown rump length (CRL) of the baby

Please note that any scan at 10 weeks is unable to check baby's anatomy (physical health) properly. It is because small size of the baby and incompleteness of its embryological development.

From 12 weeks we will be able to perform Early Baby Test to check fetal physical and genetic health.

How do we perform Viability Scan?

Viability scan is MUST condition and we perform it before blood sample to confirm normality of the pregnancy.

Our advanced ultrasound technology allows performance of viability scan transabdominally.

We do NOT need full urinary bladder for the scan. Please feel free to empty your bladder before the scan.
