Hello,
I just wanted to start a thread here to make it more widely known about these risk-free tests for Down's syndrome and other anomaly markers.
So if you get back worrying odds from your first scan with regards to Down's syndrome you have a choice on the nhs of a cvs test or an amnio, both of which carry a very small risk of miscarriage.
These blood tests, 'Harmony' tests, are another option. They can detect and then analyse foetal DNA within the mother's blood stream, and although they are not diagnostic they are 99% accurate. And because they are a simple blood test they pose no risk to the foetus.
Unfortunately they are private and therefore expensive. The harmony tests cost £400. They also offer a scan for £180 where they look for multiple markers for Down's syndrome (whereas the nhs only look for the nuchal fold measurement). If you are early enough in your pg they can redo your hormone blood test too (included in scan cost).
The Harmony test results take 10 days - 2 weeks to come back. But I had the scan yesterday and that alone was so reassuring, all the stuff they look for as markers for Down's syndrome were completely absent. They redid my bloods and they came back damn near perfect (whereas my nhs results were a bit worrying) and the lovely doctor recalculated my odds - they went from 1:397 to 1:1654. And she said it was only my age (40) preventing the odds from being in the higher thousands.
So hopefully the results from the Harmony tests will confirm that!
We couldn't really afford it and have just whacked the cost on our overdraft...and I know that my original odds weren't terrible....but the odds with our first DC were 1:4000 so hearing 1:397 for this pg was concerning.
Just wanted to put this info out there.
I had the tests done at the Fetal Medical Centre on Harley Street in London. The clinic is headed up by Dr Nicolaides, who is world renowned. I think he was the person who pioneered IVF. He developed the tests and is pushing for the nhs to offer them to everyone. The centre is non-profit, all the money goes back into research.
I don't think their website has info about the harmony tests, but if you call up they can tell you about them and book you in.
You can get the tests done at other places than the FMC too but I don't think they are that widespread yet.
Hope this helps someone out there! I was so grateful to learn that we had this option.
