The IONA® Software automatically processes sequenced DNA fragments and maternal age (prior risk), into a self-contained or printable report. IONA® test results are exportable in common formats to enable local, off-line further analysis and monitoring, if desired. Reports can be customised to meet hospital or clinic requirements and can be translated into local languages.

IONA® test results are reported as:

Low Risk: it is very unlikely the pregnancy is affected by trisomy 21, 18 or 13

High Risk: the pregnancy is at increased risk for trisomy 21, 18 or 13 and the result should be confirmed by a follow-up invasive procedure, such as an amniocentesis or CVS.

No Result: very occasionally there is insufficient placental DNA in the sample to obtain a result. Women may be asked back by the healthcare provider for a further blood sample.

Fetal sex determination

The IONA® test offers optional testing to determine the baby’s sex. A “sex determination failure” result may be reported if there is insufficient data to support the sex determination analysis. A failed result does not reflect on the quality of any other result generated by the IONA® test.  Please note that the sex determining technique is not a screening test for rare sex chromosome conditions and is not currently available for multiple births except for identical (monochorionic) twin pregnancies. We therefore recommend that fetal sex determination is confirmed by ultrasound.

Fetal sex determination is only available for singleton and monochorionic twin pregnancies. It is only offered in regions where fetal sex determination is permitted.
