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 or the selected SCAs or AAs
- High Risk:the pregnancy is at increased risk for trisomy 21, 18 or 13 or the selected SCAs or AAs and the result should be confirmed by a follow-up invasive procedure, such as an amniocentesis or CVS. There are several organisations available that provide support to parents through the antenatal testing process. Click here for details of additional support.
- 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 and IONA® Care offer 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 IONA®.
Please note that the sex determining technique is not a screening test for rare sex chromosome conditions (these can be screened for using IONA® Care) and is not currently available for multiple births except for identical (monochorionic) twin pregnancies.
Fetal sex determination is only available for singleton and monochorionic twin pregnancies. It is only offered in regions where fetal sex determination is permitted. We recommend that the fetal sex is confirmed by ultrasound.
