Nifty/harmony - which to choose?

[Slavetominidictator]

Am 8 weeks pregnant and keen to have these non invasive tests done. Would anyone recommend one over another?
And is the Fetal Medicine Centre the best place to get them done? I'm in the south east but only half an hour from London.

I have googled but can't seem to find anything that tells me where or the pros and cons of each.

We had the Nifty done at around 11 weeks at This is my Leeds with Mr Gerald Mason and were very happy. Results, which were low risk for all three trisomies, (numbers in the millions) came back in around a week and were very competitively priced.
Think this link to their clinic explains the differences between Harmony and Nifty. www.thisismy.co.uk/nipt-non-invasive-prenatal-testing/
