Harmony test accuracy

Good morning everyone! I am 13 weeks pregnant and had the harmony gender blood test done last Friday. I will be hearing back sometime this week what the sex of the baby is.
I am very excited. Although I have heard horror stories of the test being inaccurate. Most of those stories had the mom doing the test before 10 weeks though.
Has anyone else done the harmony test (also known as Jack and Jill test) ?
Was it accurate for you?

It was accurate for me, but a specialist did tell us that it has some false positives occasionally. She wasn't referring to gender though.

I have never had one of those test done, but here is a bump:)

Harmony and Jack or Jill are two different tests. The Harmony genetic screen has a high rate of accuracy as far as the sex goes unless there are closely spaced pregnancies. If it's been less than three years it's possible to pick up fetal dna from a past pregnancy.

Jack or Jill's labs have apparently had issues with cross contamination, sometimes dna from lab workers has even ended up in the sample skewing the results.

I've had both Harmony and Panorama done and the were both accurate.

Thanks for the info

I did Panorama, which is supposed to be the most accurate on the market, (99.64 versus 99% so not a crazy difference). If there is an error in fetal sex it's usually a lab error (samples got switched). Lesser chance is a chromosomal intersex issue. There is a chance if you had a boy within the last three years to pick up his chromosome but that is unlikely.

It's been less than three years since my son was born it's only been 2.5 years :/ oh well

It's still early pretty rare, they have been working to isolate things, but I'd wait until u/s to be sure. You can have an elective in a week or two

My OB office only does 3 Ultra sounds one right around 8 weeks one at 20 and another around 36 so it looks like I'm waiting until the 20 week Anatomy scan which is fine

We're doing an extra elective one later on for 3D. I wanted to get one at 16 weeks to confirm sex, but we got too busy lol
