Diagnosis

Non-invasive prenatal test (NIPT)

Tests to understand where your symptoms come from before deciding anything.

Frequently asked questions

Screening for the main chromosomal conditions in the baby from a blood sample taken from the mother.

From week 10 of pregnancy, the mother's blood carries fragments of DNA from the placenta. Analysing them estimates the risk of trisomies 21, 18 and 13, among others.

It is a highly reliable screening test, but not a diagnostic one: if the result is abnormal, it is confirmed with an invasive test before any decision is made. I explain everything calmly, before and after.

Frequently asked questions

If the result is abnormal, does that mean my baby definitely has that condition?

No. It is a highly reliable screening test, but not a diagnostic one: what it gives is an estimate of risk. If the result is abnormal, it is confirmed with an invasive test before any decision is made, and I explain calmly what each step means.

Why is it called non-invasive?

Because it is done with a blood sample from the mother, without touching the uterus. From week 10 of pregnancy the mother's blood carries fragments of DNA from the placenta, and it is that DNA that is analysed.

Does it detect any condition the baby might have?

No. It estimates the risk of the main chromosomal conditions — trisomies 21, 18 and 13, among others — not of any illness. It is a specific screening test, not a complete genetic study.

Other diagnostic tests

Whether a test or treatment is right for you is decided together, in consultation, after assessing your case. This page is for information only and does not replace a medical assessment.
