The IONA® test is a non-invasive prenatal test (NIPT) for pregnant women which estimates the risk of a fetus having Down’s syndrome, Edwards’ syndrome and Patau’s syndrome. The IONA® test is an advanced screening test that is carried out on a small maternal blood sample. Pregnant women can expect test results within 3-5 working days from sample receipt. The IONA test will now also test for XY chromosomes to determine the baby’s gender.
What are the advantages of the IONA® test?
Safe: non-invasive with no risk of miscarriage
Fast: the IONA® test is the fastest NIPT available with results provided within 3-5 working days, from sample receipt.
Accurate: greater than 99% for detection of trisomy conditions (assumes no rare difference between placenta and fetus).
Simple: uses a simple maternal blood sample taken from the a vein in the mothers arm
Quality: the IONA® test is a regulated diagnostic which is CE-marked and the test is analysed in a Care Quality Commission (CQC) regulated laboratory.
During pregnancy the placenta leaks fetal cell-free DNA which circulates 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 fetal trisomy 21, 18 or 13 is present.
Traditional screening offered during pregnancy is currently called the combined test. This is an ultrasound scan to measure the nuchal translucency (NT) and a blood test. This is much less accurate than NIPT and it only detects around 85% of babies with Down’s syndrome.
The IONA® test has a higher detection rate than the current combined test offered to pregnant women. This means that fewer pregnant women will undergo unnecessary invasive follow-up procedures such as amniocentesis or CVS (chorionic villus sampling) which are stressful, painful and can carry a small risk of miscarriage.
How are the IONA® results reported?
- Low Risk: means that it is very unlikely your pregnancy is affected by trisomy 21, 18 or 13.
- High risk: means that your pregnancy is at increased risk for trisomy 21, 18 or 13 and the result should be confirmed by a follow up invasive such as amniocentesis.
- No result: Very occasionally there is insufficient placental DNA in the sample to obtain a result. Women may be asked back by your healthcare provider for a further blood sample.
