IONA is a non-invasive prenatal test, that can be carried out as early as 10 weeks into a pregnancy on a small maternal blood sample.

Maternal blood sample contains a mixture of fetal and maternal circulating DNA. IONA 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 21, 18 or 13 is present.

This test measures the number of chromosome copies in the woman’s blood which can be related to conditions such as: Down’s Syndrome (T21); Edward’s Syndrome (T18) ; Patau’s Syndrome (T13).

If fetal sex determination is requested, the accuracy is greater than 99%.
