Gender blood test said girl but ultrasound today said boy

[ruby14]

Hello,

I've been TTC a girl with the help of atomic and a personalized sway plan. I fell pregnant in December and had a gender blood test at 16 weeks that confirmed girl. Today in my 20 week scan the sonographer found boy parts. Feeling completely gob smacked and don't know what to believe now. I'm pretty sure I saw boy parts too :(

I has a specific gender blood test in the UK by gtldna. I've read other tests like harmony can be inaccurate for gender but that's because they are not predominantly for gender. Not sure why that matters, if u/s showed boy...but mind is going crazy.

I would believe bloodwork over an ultrasound. Do you have the photos?

[foxymrsg]

Sorry to hear you're going through this turmoil. I don't know enough about the blood tests to offer advice I'm afraid but wanted to send you hugs X

[Erin514]

Have you had a chance to talk to your doctor about this? He/she would hopefully know more about the accuracy of each method and be able to tell you which one to trust. Wow. I can only imagine your confusion!

[essnce629]

Atomic says to believe blood tests over ultrasound as the ultrasound tech is only human and can make mistakes. I totally agree but I too would be a wreck if first told girl, then boy. FX the blood test is right.

Blood test 100%. Now, I dont know about what type of test you did. I sure know Harmony has 100% accurancy

Harmony has a better accuracy than those tests. I personally know of a woman that got a girl from that blood test but has had numerous scans since with different techs and has been unmistakable boy. Good luck and I hope you get the outcome you want!

Thank you for your support. As I'm in the UK we don't see GP about pregnancy or to confirm scans or tests. I can only go on what the sonographer has said and the company who run the gender test. I didn't get a photo of the u/s relevant parts, we just saw it on the screen.

This is my second child and at our DS scan it said boy and we convinced ourselves the scan was wrong and did loads of research about it. Well he was a boy and now we have him would never dream of him being anything different. I can't go through the same ordeal of trying to convince myself the scan was wrong. I just can't believe after the sway and getting the blood test as a girl that the scan shows a boy.

Blood tests are supposed to be 95% accurate but if someone in the lab has made a mistake - either not checked for the Y chromosome properly or mixed up my results with someone else, whatever, then how I can rely on them?

I hadn't wanted to be in the position of disappointment and when I got my blood test results I was really prepared for it to be a boy. But as the results was girl I let myself be completely free to want my girl and now I've been through the emotion of knowing I have a girl, for it all to be taken away.

Thank you again for your thoughts - I feel like I just need to let out some emotion!

[Erin514]

What a terrible situation to be in. Most of us here can relate to hoping/praying pink and getting blue (or vice versa), but to be given apparent confirmation of your desired gender and then have it thrown into question... ugh. That's really rough. I'm so sorry.

[familymatters]

The blood tests are supposed to 99% accurate, especially if they are done well after 10 weeks. I'd be contacting the gender blood test company and demanding a re-test

They're not actually 100%.

The unfortunate slim margin of error lies with the blood test picking up the mom's XX. When there are errors, it's usually the accidental belief it's a girl because of this.

It's SO rare though. OP, have you gotten another blood test done?

I've contacted them to ask if they will re-test so I'll see what they say. I was also thinking of having a 4d scan - do you know how accurate they are?

[familymatters]

A 4d scan can't hurt, I would say it was fairly accurate.... But then again I would have thought the blood test was very accurate lol

I'm so so sorry Hun. I hope you can get a rescan or another blood test. You must be so distraught right now and I can't even imagine. I hope the scan was just a funny angle or something and baby is all girl.

[Mamato3?]

I really don't know what I would do in your position.... I trust blood tests more than ultrasounds, but there have been wrong results before with them, very rarely though compared to ultrasounds.
The truth is that only after birth we can be 100% sure about gender. I hope the u/s tech was wrong.

[Mulberry Smurf]

With the blood test being one of the home test kit types I would be a little more wary of trusting that result, especially as 5% is quite a large margin of error. I think another scan and even a harmony or panorama test would help to clear it all up. Good luck, sorry you're in this position xx

[ever hopeful]

I'm so sorry you are going through this. I hate to say but I don't think the results of the blood test you did are brilliant - even with Harmony which is way superior I still don't think it's 100% guarnateed, although 99.9..... I had a friend who used a cheap gender test (under £200 in the UK when I was pg with my DD and had an opposite - the other way round though, obviuosly don't know if it's the same one). If I was you and so you don't drive yourself nuts worrying I'd book another u/s at somewhere very good eg. Faetal Mecial Centre in Harley Street The Fetal Medicine Centre (http://www.fetalmedicine.com/)
- and explain what has happened and that you really need to know the gender. Good luck and I really hope it's wrong and you get your girl. x

[Beau82]

Oh gosh, I'm so sorry you're going through this. How absolutely heart-breaking to be pulled back and forth like that! I would definitely book another scan if you can. I don't think 4D are very accurate for gender but usually they also have 2D capabilities so I'm sure they would check that as well.
I know sonographers can be wrong but usually it's that they say girl when it's actually a boy but I have read that a cord can cause confusion and also swollen labia. I so hope the blood test was right.

[atomic sagebrush]

Blood tests done in the lab are VERY RARELY incorrect. Ultrasounds are incorrect all the time. Do you ahve some pics we can see???

Edited to add - the at home tests can be incorrect more than the lab test.

[atomic sagebrush]

With the blood test being one of the home test kit types I would be a little more wary of trusting that result, especially as 5% is quite a large margin of error. I think another scan and even a harmony or panorama test would help to clear it all up. Good luck, sorry you're in this position xx

Is the blood test a lab test (Nipty or Nifty test like Harmony) or did you do it yourself at home??? Those are less reliable.

[ruby14]

I took the sample myself at home and sent it off to the lab. I have read they are less reliable because of contamination but that would only be the case if I was told boy and it was a girl. The only room for error in my case (that I can think of) is that the sample wasn't checked thoroughly enough to find the Y chromosome, or my results were mixed up with another persons. At 16 weeks there should be plenty of fetal DNA in my blood so again, less likely to be an issue with the sample due to that reason.

I called them and even the lady confirmed that its unlikely to be wrong if they say girl. More likely the scan is wrong but I have a very clear image in my head of the scan and can't see how that can be wrong. The sonographer was adamant that the shape was that of a boy and there were no "3 lines" that girls have. Plus I just don't want to put myself through the turmoil. I have booked a private gender scan tomorrow to see what they find.

Thank you again for your comments. I don't feel so alone in this with all your replies.

[Boom]

Surely it's less likely to give an incorrect 'boy' result than girl as something not found does not mean it's not present. So sorry you are going through this uncertainty

[ruby14]

Confirmed boy on the private scan today. Number of shots that clearly show the relevant parts.

[Babygirlquest]

I'm sorry you didn't hear girl :-( I hope you can get your money back for the inaccurate test as it really gave you false hope. I hope you are ok. Hugs.

[Mulberry Smurf]

Sorry you didn't hear girl at the scan today and that you've been through all of this. Hope that you can get some reason why the result was incorrect from the blood test. Xx

[Traci25]

So sorry, hang in there. You'll be in love the moment you meet him!

[nuthinbutpink]

What test was it?

[subban]

Same thing happened to me when pregnant with DS3. I did the Tell me pink or blue test and was told it was a girl. After my 13 weeks sono where I saw a clear boy nub I contacted the company and they were adamant the test was right... DS 3 is now almost 4 and he is ALL boy. It made my GD so worst to be told Girl by this test. I'm really sorry you have to go through this... Big hugs

[atomic sagebrush]

Oh no Ruby I'm so sorry. I agree most likely is that they mixed your results up with someone else. :(

Please let me know if I can help in any way.

[essnce629]

Oh no Ruby, I'm so sorry! I can't imagine what a roller coaster of emotions you've been through. Take the time to grieve in whatever way you need to as I'm sure it feels like a loss of sorts.

[maidentomother]

Unfortunately those home blood tests are completely unreliable, they don't actually perfotm a test. You might as well pay for a coin toss. These scams make me so angry and have caused so much drama and upset.
