It has to be. I also had a friend whose baby brother was meant to be a baby sister. Although as I said, highly unlikely. We were told female. So the fact that your dr doesn't offer it isn't due to the gender aspect but that the test has a lot of false positives for genetic diseases which cause the women angst and she will have to go through an amnio which has risk of its own. From the early stages of pregnancy to when your teenagers are finally ready to leave the nest (even if they don't want to) we're here to help you through this crazy thing called parenting. If it shows XX girl if it shows XY boy so it's incredibly difficult for that to be wrong. If there is even 1 they say boy.. if none then girl. I know you are not. We're obviously concerned if the baby is showing genetically to be female but has male genitalia. You are not alone in it saying boy but it was a girl. I will keep you all updated. If I'm not mistaken the Harmony tests also gender related genetic issues - sorry if I'm wrong here, but that's what I thought from reading my results - so I would not worry about this if everything was normal with your test. Maybe they are higher risk for one of those syndromes but weren't told because they got someone elses results or their wasn't enough fetal DNA to properly screen. The chance that this is a sex chromosome issue/syndrome is a lot less likely than just the lab screwed up. Maybe you're not familiar with the test, but what it does it look for fetal DNA in the mother's blood, which is present as early as 10 weeks. SarahJacks. The DNA test (verifi, like harmony), at 14 weeks said boy so you can imagine our surprise at 32wks when Dr said its a girl. The lab could have messed up or had a contaminant. That doesn't look like any of the girl potty shots I've gotten with my two girls. Very weird. someone in this thread mentioned turner syndrome.. there's klinefelter syndrome (XXY - infertile male phenotype) , XYY (male phenotype), multiple x (bigger female phenotype and gets bigger with additional X chromosomes) and there's androgen insensitive XY where a male karyotype fetus (meaning its chromosome configuration) ends up with a female phenotype (develops as a woman) because the SRY protein, made by a gene specific to the Y chromosome, turns female fetuses into males by inducing testosterone, which is an androgen, which is what the fetus's somatic cells are insensitive to. I have read that the harmony test has been wrong for gender a few times. That happened to a friend of mine as well.

Hi, I had an Iona test at 14 weeks the sonographer told me it was a boy and then sent my bloods off, results came back low risk and also that the baby was not a boy but a GIRL! However, I almost wonder if it is some sort of test error/fluke. Harmony test gave wrong gender!?! so when in a typical XY fetus it's ovaries become testes, labia becomes a scrotum, fallopian tubes become seminal vesicles and the urethra re-routes through the clit tissue and so forth, androgen-insensitive XY fetus's reproductive tracts stay female (their usually lacking a uterus and infertile tho). Nothing is 100% accurate. Just out of curiosity, do you already have a son? I don't know how to help you, but we were told we were having a girl (based on 20 week ultrasound, not the blood test), but at birth we were surprised by a boy! The fetus has DNA at 10 weeks, it doesn't need anything else. This afternoon at our 20 weeks scan ( 20 weeks 2 days ) we were told boy. It's all gonna turn out ok. I love genetics. In that sense it is actually testing the fetus' genetic matter.It's relatively new for it to be used as broadly as it is now. This action cannot be undone. Science is so advanced these days isn't it. Feel free to contact your doctor and ask any questions you have. So there is a small chance that the test could show male when the baby is a female. said, it is either a wrong u/s or a contaminated harmony sample for some reason (vanishing twin, previous unnoticed miscarriage). It's a small number, but maybe enough to cause false results in some number of women? The point of the harmony test is not just to test for sex. I think their test is called tell me pink or blue or something similar and google is suggesting a few inaccurate results but they all seem to be when they've said girl and it was actually a boy.

You are not alone in it saying boy but it was a girl. Typically the mother was told boy and it turns out to be a girl. Zygotes are females at the outset, anyhow. : Hi there. So the vanishing twin who is a male is the weak link in that test! Was told boy numerous times but came out as a girl. However, I almost wonder if it is some sort of test error/fluke. This week she's 20 weeks, and the ultrasound definitely shows male. I have also read it can come up boy and be a girl in a vanishing twin case. Harmony test says it's a boy ultrasound says it's a girl. Laugh it off. Well, their test is saying boy so I'm all over the place today. I also think 10 weeks is one of the earliest times it can be taken, so probably a bit more likely to have missed the Y than had it been taken a few weeks later. There’s nothing wrong with the (now 16 year old) child, just a fluke. Sort by: Oldest Newest 118 Posts. Wait what? We are waiting to hear back from her OB/GYN on what exactly they think happened, because they were unsure. In addition to this, I also heard that if this is your second child, and the first was a male born fairly recently, some of the Y chromosomes from the first child might still be present in the mother’s blood. I hope your results get resolved soon! Here is an example: https://www.babycenter.com.au/thread/3189598/harmony-test-gave-wrong-gender.
