Opinion Needed- Gender Test

edited January 2015 in July 2015 Moms
My doctor had me take a gender blood test about 2 weeks ago. Today I found out the sex of my baby. I am wary if this test is accurate or not. I don't want to tell anyone before I know for sure, we are planning on telling everyone in 2 weeks. I am debating getting an ultrasound done at 16 weeks (2 weeks from now) to confirm the test. Is this crazy? This is my first child and I was not aware of these blood tests and have never met anyone who had this done or knew about it. Any advice would be great. Thank you in advance!

Re: Opinion Needed- Gender Test

  • Thanks. My worry is they look for a Y chromosome in my blood. But I worry that in that sample taken, there might not be a Y chromosome but could still be floating around my blood stream...

  • Cell-free DNA testing is really accurate.  Likely more accurate than early anatomy scans.  There's always a chance that the lab screwed up with anything, but I'd go ahead and trust it! It'll make for a fun story if you have to tell everybody that baby Jill became baby Bill later on ;)

  • That's the info I received from the nurse. How does it work?
  • If it's the kind of test like I had (Panorama-but they have different kinds), then they not only do the genetic screening but you find out the sex.  Those results are like 99% accurate.  When I had my u/s a few weeks later, the tech confirmed what the blood test already said.

    I was new to it too-I'm a FTM and I'm over 35, so I got it because of that.  I would go ahead and find out the results, it's legit :) 

  • Thanks. I guess I'm just worried because it's so early on. Im only 14 weeks.

  • As everyone else has said, those tests are very accurate, so it's safe to say congrats on your baby girl!

    I was told by my genetic counselor that they are extremely reliable, like 99%. One example of a possible error she gave is if I had had IVF and there were still remnants of an embryo that didn't implant.  That embryo's DNA might show up and give a false result.  I might not be explainning that perfectly, but you get the idea.
