The results of your IONA® test should be discussed in detail with your healthcare professional.

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 with an accuracy of 99%. However, in about 4% of cases, a “Technically Inconclusive” result may be reported if there is insufficient data to support the sex determination analysis.  An inconclusive 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.
