The j&j test is definitely a scam. The Barcelona clinic could be the real deal. How much blood did they draw from you?

[Claire33]

The J&J test has two versions, the one taken in a lab which is legit and the one taken at home (drops on a paper) which is a scam. Have you taken that one? The Barcelona test seems legit, but I cannot be 100% sure until I get an ultrasound at week 20.

Some of the ones with the blood on paper are legit. They're less reliable and can get cross contaminated from DNA in the environment and so aren't the best tests for that purpose.

Yes, it is early, I was 7 weeks 5 days. The clinic does the test from 8 weeks, but research shows results already from 5-6 weeks. It is not 100%, there is a margin of error of 1-5 %. Here is the link to the clinic (Barcelona) and some sites with research about the technique. It guess it's about as reliable as an U/S in week 16. That is why I'm not counting my horses at the moment. In the US there is something called the new Jack and Jill test, I wonder if that is a similar test to this one? You have to have your blood drawn at a lab, not one of those blood on paper at home things.

Thanks for sharing those! I had thought before that the blood tests may be reliable a bit sooner than they've been doing them. FXFXFX!

There is no way there is enough fetal DNA in a 7w dried blood sample on paper.

Ok, I will clarify. The IN LAB blood tests I have wondered if they may be reliable earlier. The on paper lab results are less reliable no matter how you slice it but they were shown in some studies to be at least somewhat helpful, unlike the urine and saliva ones which are not at all reliable.

I am so excited for you!!! FINGERS CROSSED!!

[maidentomother]

Yep, I agree the lab ones can be done earlier. The less the woman weighs and the more blood they take, the earlier testing will yield results.

The harmony test can be done as early as 5 weeks. But, only for gender. Chromosome testing isn't done until 10 weeks (I work at my OB/GYN)
