IONA, a non-invasive prenatal screening test for Down's Syndrome and other serious genetic conditions. 

Kingsbridge Private Hospital is delighted to offer a new genetic screening test for expectant mothers.

The IONA test estimates the risk of a fetus having Down's syndrome (Trisomy 21), Edwards syndrome (Trisomy 18) and Patau's syndrome (Trisomy 13).

The IONA test also offers optional fetal sex determination.

What are the advantages of the IONA test?

SAFE: non-invasive with no risk of miscarriage

FAST: the IONA test is the fastest non-invasive prenatal test available with results provided within 10 working days, from sample receipt

ACCURATE: greather than 99% for detection of trisomy conditions (fetal sex derterminatoin is greater than 97% accurate)

SIMPLE: uses a simple maternal blood sample

LOCAL: unlike other tests, the IONA test is performed in a laboratory local to you

QUALITY: unlike other tests, the IONA test is a regulated diagnostic, which is CE marked

How does it work?

During pregnancy the placenta leaks cell-free DNA which circulate in the maternal bloodstream. As a result, a maternal blood sample contains a mixture of fetal and maternal cicrulating 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 a fetal trisomy is present.

Who can have the IONA test?

  • Suitable for women who are at least 10 weeks pregnant
  • Suitable for all singleton and twin pregnancies
  • Suitable for IVF and surrogate pregnancies
  • Unsuitable for women with cancer or with a trisomy or who have undergone a blood transfusion with the last 12 months

The IONA test complements the comprehensive range of antenatal services currently available at Kingsbridge Private Hospital. For further information on our antenatal packages, scans, tests and diagnostics, please visit our pregnancy page

Patient Testimonials

"I was in your facility yesterday for a day procedure (operation on my left arm). I wanted to write and express how impressed I was with the facilities and more importantly the staff on the Ward.

Everyone was excellent, and I mean excellent, i don't normally write congratulatory e-mails so this is high praise in my view. The Senior nurse was excellent, as was the Theatre nurse and the anaesthetist. Even the assistants that helped with catering and other duties. All came together to form a great impression of the establishment." Jason Carpal Tunnel Surgery, Kingsbridge Patient
"Amazing 5-star hospital.  Have had other surgery here before on my back.
Yesterday's was a neck disc replacement operation.  I would highly recommend this hospital like a hotel manner. Thanks again guys." Mr Phillips, Kingsbridge Patient
"As hospitals go this one is pretty amazing! Had surgery with Mr Molloy at the end of October and have another one the end of this month. Mr Molloy is a gentleman who puts you at ease right away and ensured my last procedure went smoothly! From start to finish all the hospital staff go above and beyond to make your stay as comfortable and stress free as possible. The facilities are brilliant with the rooms spacious and modern to recover in. Keep up the good work!" Ms Roulston, Kingsbridge Patient
"Can’t praise Kingsbridge Private Hospital enough!! I had an operation a couple of weeks ago and I was so well looked after. My surgeon Mr Rashid was fantastic, and the nursing staff was also fabulous. I found they communicated very well to each other, so everyone knew when my meds were due, my allergies etc. They were so kind, so lovely, constantly checked to see how I was i.e. my temperature etc. The food was fabulous and the catering staff very helpful having had an operation were very happy to accommodate ... Thank you to all!" Ms Cheong, Kingsbridge Patient
"Currently just back from recovery on the ward. I have just had ACL reconstructive surgery on my left knee. What can I say? This place is brilliant. I arrived at 8.35am, taken to the ward at 8.45am (my admission time was 9am). Tended to by a lovely Nurse. Dr Roger Wilson spoke to me around 9.45am, in Theatre for 10am, recovery for 11.10am and now currently back on ward. These guys are awesome. From the consultant to anaesthetist to nurses to cater assistants. Absolutely brilliant. Thank you so much. I am so grateful to everyone at Kingsbridge for the service." Mr McNicholl, Kingsbridge Patient
