IONA Prenatal Test
IONA, is a non-invasive prenatal screening test for Down’s Syndrome and other serious genetic conditions. The test estimates the risk of a fetus having Down’s syndrome (Trisomy 21), Edwards syndrome (Trisomy 18) and Patau’s syndrome (Trisomy 13).
The IONA test also offers optional fetal sex determination.
FAQs
How does it work?
During pregnancy the placenta leaks cell-free DNA which circulate in the maternal bloodstream. As a result, a maternal blood sample contains a mixture of fetal and maternal circulating DNA. The IONA test directly measures the amount of this cell-free DNA and can detect small changes in the DNA ratio between the maternal and cell-free DNA when a fetal trisomy is present.
Who can have the IONA test?
– Suitable for women who are at least 10 weeks pregnant
– Suitable for all singleton and twin pregnancies
– Suitable for IVF and surrogate pregnancies
– Unsuitable for women with cancer or with a trisomy or who have undergone a blood transfusion with the last 12 months
