Expectant mother and nurse

Non-invasive prenatal testing (NIPT)

Based at Queen Charlotte’s & Chelsea Hospital’s Centre for fetal care

About the service

Similar to the “Harmony test”™, NIPT is a technique for prenatal screening for Down’s syndrome (trisomy 21) as well as other genetic abnormalities like trisomy 13 and 18. As opposed to amniocentesis or CVS (chorionic villus sampling), the test is completely non-invasive and there is no risk to either yourself or your baby. We offer early morning and evening appointments for your convenience.

What does the test involve?

The examination is carried out by a simple blood test, any time after 10 weeks’ gestation confirmed by an ultrasound scan. The result is usually available within seven to ten days.
