We do have a similar test in the uk that we can get, it is called Harmony. It detects chromosomal abnormalities and can also tell gender early on, I was 13 weeks but it can be done earlier. I had mine done through a company called Babybond (costs a lot though £500). I had it after finding out risk of DS is 1-130 after 12 week scan. There is a 2 week wait for results as your bloods are sent off to America for testing, look it up on the internet it is available!
