Prenatal paternity test with DDC.

Hey. I apologize in advance for my written English im German.
I had protected sex with an old flame. Guy 1. we used a condom. this happened on July 25th. he is quite sure that the condom did not break. he guarantees that he checked it afterwards. the day after, July 26, I was on a date with my ex. we have seen each other on / off for the past year. we had unprotected sex. so did we on July 27th. on 30 I again had sex with guy 1. my old flame. again protected sex. he once again assured to have checked the condom afterwards as he has 3 children  with his ex and does not want more children. I had my first menstrual day on July 15th. my cycle I think is 27-29 days long. i think i had ovulation around d 28/29/30 July.
according to a scan, it fits with the first day of my last period.


I had no doubt whether it was my ex boyfriends child. right up until I started reading online.

I contacted my midwife who took a blood test on me. i contacted guy 1 who i met the same day and saw that he made mouthswaps (is that the right name?). I even packed it down with the midwife and it was shipped off. it should just be added that my midwife's test kit is DDC but they use EasyDNA in the UK as an intermediary.

guy 1. my former flame is very cooperative and in no way want to have a child with me. He is the one I had protected sex with.

I was told that there was not enough DNA in my blood. i was tested in week 8 + 3. then I was tested in week 10 + 0 and it was sent off. I sent it with a reply within 3 working days after it was received.

he is excluded as the father. and very happy with the result. he relies 100% on the test and he fact that we used a condom, supports the test. He says.

I really want to trust the test. which I mostly do too. but I was willing to have an abortion if he was included.

my ex, who now, after testing positive, is Working on building a relationship
with me to be my boyfriend is, looking forward to being a dad. he doesn't know about guy 1. I read many stories about paternity tests and can see that most bad reviews about DDC are their customer service. here in these forums it is probably more doubt whether the test is correct and those who appear to have a valid history of failure do not seem to have seen their ex / husband/ boyfriend  when they took the test. which also makes me see it more as an error / Freud that occurred when collecting the sample.

The test says:  

Probability of Paternity: 0.00%

The alleged father is excluded as the biological father of the fetus.

Testing was performed to determine paternity using cell-free fetal DNA (cfDNA) isolated from the plasma of the maternal blood sample. This sample contains a mixture of maternal and fetal DNA. DNA was also isolated from nucleated cells in samples from the mother and alleged father. All DNA samples were analyzed using next-generation sequencing (NGS) technology. Paternity determination was performed using 1661 SNP (Single Nucleotide Polymorphism) informative loci out of 2,304 tested loci to generate a probability of paternity.

What does 1661 snp out of 2304 tested mean? Is it enough?

And .... do you Think a can trust the exclusion?

thanks in advance!

Maria, now week 11+5.

I have chosen to have an abortion today.. I read in several forums/websites how everyone who has had a doubt an not been able to enjoy the pregnancy and for many it has been unbearable.
I am only in week 11+ and have therefore chosen an abortion. although I have also spent many hours reading about ddc and there results. I have so far only seen how their results have been confirmed after birth. which is so amazing! but I personally cannot be in these feelings for the next many, many months.
I wish you all the best of luck with your pregnancies and births!

How other women deal with ambiguity and anxiety during their pregnancies doesn't matter, the question is how you would, since you are the person who is pregnant. It sounds from this decision like you are saying, it is unbearable for you.
yes I couldn't be in it. did not sleep at night and felt slightly depressed. it feels like the right decision
I don't want to ask too many questions that seem irritating, but I assume you did consider adoption?
it is not widely used in Germany. I would not be able to do that either. There is a huge difference between Europe and the United States on that point as well.
but it is also impossible for me - the person I am and What I believe  in. we have free abortion for week 12. Not more than that. In uk its week 24 and sweden week 18.
it was the right choice for me. which it probably is not for many others in here :)

Hi!
and thank you for your very elaborate answer.

I meant since I tested positive for pregnancy.
my ex was not the one who tested positive :)
I also don't think I can find anywhere that DDC made mistakes in their lab.

then it has probably been due to how the DNA has been handled until it arrived at them
. consciously or unconsciously. I also think that it is because of my nervousness about the situation that I doubt the reliability of the test.

Sweetheart, that is all it really is. For some reason, it is very easy for women who have nervousness related to being pregnant to let the anxiety float to and settle on the question of paternity, even when the real questions are how to pay for things and where to live and what to do for child care and whether or not to marry the dad. As you work out answers to things like that, you will find your anxiety about paternity going away.

Take care. You are one of the lucky ones. Babies don't always come at a convenient time, but they are such a joy.

   I contacted EasyDNA which is the intermediary to DDC. told that I was anxious about the result and whether I could trust the result. He wrote back several times and in the last mail (which was primarily a clear repeat of the previous mail) he wrote the following:


Thank  you for contacting easyDNA.

As mentioned this is a 100% conclusive result as no markers match and based on the samples that you have sent in, as you have witnessed the sample collection of the father i can confirm that he is not the father as there was no possibility for him to swab someone else.  
I live in a country where we are quite privileged in terms of the health system, day care and in addition I have a good high education and a good paid job. which the father of the child also has. so at that point I feel well prepared.
I was just about to have an abortion if it turned out to be my old flame...

But, According to those who have returned with answers after giving birth, it sounds like it is correct. I also assume that they can validate that it has been done correctly when the sample was taken?

those who write that the test is not accurate  sound more to not have attended egen the test was taken?
Online, some people are telling the truth, some people are telling the truth as they understand it but misunderstand something, some people are making things up for reasons of their own. It is almost impossible to tell, but the one credible report we have seen where there was a mix-up was one in which the woman did not attend when the sample was taken.

If you have written to EasyDNA several times and have been answered properly by them several times and you are still unwilling to believe your test results, there is not much more anyone can do to reassure you about this test. Why don't you consider using Ravgen and testing with the other man (the child's father) using the "discreet test" method if you cannot bring yourself to admit to him that you want a DNA test? Like the DDC, Ravgen has arrangements all around the world for collecting samples, and they are the best.

As I said already, honesty is simpler, and trusting the DDC's results is cheaper, but it is beginning to sound like you are unable to let go of your fears. So, there is the Ravgen option, with the test your ex will never know was done.
it's not about not believing in the result or the test. but my fear of an incorrect result and that I have put myself in such a situation.

It is a large company that only makes DNA tests. and prenatal paternity tests are proven to be correct in reputable magazines such as the New England Journal of Medicine through a study.

If a large and reputable company made mistakes in such tests, then I think we would also hear about it ...

it's just that fear. it controls...

Btw. in several posts in here, it seems that there is one story thats supposedly true ..

i read about a woman in here in this forum who in 2015 i think wrote that she had received an incorrect answer from ddc in her prenatal paternity test. she claimed it was her boyfriend's and that she only took the test to prove to him that it was his. he was excluded. he refused to talk to her. she talked about that she had hired a lawyer and that she would sue ddc. later  she told that the baby was born and the test said he was now included?

I fell over a conversation on whattoexpect.com where exactly the same thing is happening.

. there she just calls herself ElizabethGlass. She writes that he is crushed by the result and will not talk to her even though DDC offers a retest.
She also writes that they are not in a relationship but old friends and that it turns out that he has a fiancé in another state who required this test.
since I've read both stories from these people, I think it sounds very similar. however, with slight variations. and it doesn't sound like they were both present when the blood tests were done.

it's a story I've read that some in here point out as being the most trustworthy. but after encountering it somewhere else under a different name and with small changes, I have little doubt whether it is true or not ?! this takes place around Aug / Sep 2015
As has been shown in a lot of other situations (not all of them online, but why not go online and do it too?) people with psychological issues will claim very complicated and persuasive things. Once on MedHelp a woman wrote in, saying she was pregnant and was watching her neighbors' children for the weekend, and that their parents were taking a car trip and she had just learned that they had been killed in an accident somewhere in another state. She added lots of persuasive details and people all over were trying to help her, to locate the place where the people had supposedly gotten in the crash, and to find social services for her. She kept things going for many days before it became clear it was all a lie. Trolls exist.

Certainly if you found almost exactly the same story on another site at around the same time, but with key details changed to make the situation just a little more impossible, it is quite plausible that this was just someone trolling. I used to think that our trolls were picking on certain companies because they worked for the competition, but now I just think they do it to stir up panic among women who are already anxious about their situations.

You went to one of the top two labs in the world for this kind of test, and you are in a good situation in almost every way in terms of being able to raise a child, with a strong social-services safety net. Try not to obsess (write multiple letters to the lab, look for stories on the Internet) over this, since it is a false concern. If you cannot shake the worry, see a counselor or therapist to figure out what is behind your concern.

Good luck!

Hi, and welcome to the forum.

You ask if 1661 SNP is enough. Especially since they are a U.S. company, where people can (and will) sue for something called "wrongful birth" if a mistake is made, I would trust their assertion that testing 1661 SNP means 0.00%. They would equivocate, if it was not enough according to their scientists. The DDC has a good reputation, and it has professional reasons to get it right, and legal reasons as well.

We get the question of whether a reputable lab could be wrong on this forum pretty much only when the woman has only tested with one man. Something about hiding from the important person that a DNA test was necessary makes women worry about even the best of labs. You said "my ex, who now, after testing positive, is Working on building a relationship..." did you really mean he, himself, tested positive? Or were you merely saying that since your flame tested negative, you are assuming your ex tested positive?

Obviously the easiest way to be confident in a prenatal DNA test is to test with both men. One of them will be excluded and one will be affirmed, and each test confirms the other. If you are saying that you did test with both men and your flame came up negative and your ex tested as the father, just believe the tests and relax.

However, because you are not certain, it sounds like you only tested with the one man. If that is the case, you have two choices. You can believe the exclusion, which sounds pretty definite. Or you can test with the other guy. (And, lest you think that is perhaps redundant, believe me, some women who have written in on this site have done not two, but three tests before they can bring themselves to believe the results. It isn't because of lab errors but because they are just so anxious.)

My suggestion is that since you saw the swabs handled correctly and do not suspect any kind of fraud, and since the results from the DDC were definite, you should go along with your flame's opinion that he is not the dad. But if you are super uncomfortable, you could also do a test with your ex.

I will also note, as far as reports on this forum say, there are two labs that do top quality work in this field, Ravgen and the DDC.
If you do want to be absolutely certain without telling your ex that there is a reason to test, and if you are willing to pay the big fees that prenatal testing costs one more time, Ravgen does offer "discreet testing," using a guy's toothbrush or a swab taken from the edge of his drinking glass. Honesty is simpler, and trusting the DDC's results is cheaper. But some women feel they cannot tell the man that a DNA test is needed because of the way the relationship is. If you are in this position and really nervous, you could go the "discreet testing" route with your ex.
