I had sex with my mistress last Nov. 20 and Nov. 21 but she also had regular sex with her Bf every week aside from the date we had sex. Now we had an ultra sound results that said on Jan. 03, 2014 she is 7 weeks and 2 days pregnant. Who do you think is the father of the baby? By the way her LMP is Nov. 13, 2013.

Thanks

You wait until the child is born and have DNA testing done. That is the ONLY way to find out.

DoulaLC · Jan 21, 2014, 04:17 AM

ScottGem is absolutely correct. The dates are too close to even give a more or less likely scenario, and ultrasound dating, while it can be close, is not an exact science. You'll have to wait this one out and see what testing shows you.

How about pre-natal dna? Am willing to pay is this method accurate? They said the non-invasive one which is more expensive can easily identify the father of the baby through the bllod of the mother after ten weeks of gestation.

Pre natal DNA testing is gaining some traction. But most doctors won't perform the process because of the potential dangers. Plus the mother would have to agree to it. What difference does it make if you find out now or wait until the child is born? Why go through an expensive and potentially dangerous process, just to find out 7 months in advance?

I believe he is talking about a blood test that is 'non-invasive'. It relies on blood samples from mom and possible dad. So far the most informative article I found that isn't an ad: New Earlier, Noninvasive Paternity Test Developed

kojack, let's put it this way. If she is carrying twins, you both could be 'the father'.

ScottGem · Jan 21, 2014, 06:46 AM

Someone else posted about these a while back and I asked J_9 about them. She said that doctors are still reluctant to do them because they are so expensive and unnecessary.

And you will know when child is born, is she is mistress, it really does not matter, since there is no relationship, you will just be paying child support later

This would be a viable option for you in your situation, especially if financial support is required by the mother for costs related to the pregnancy. This would be handled between you, the mother, and the facility you use (be sure that they are accredited and reputable).

Hi thanks all for the answer, I have already allocated the money I just want to know from you guys if you have heard about this non-evasive method of DNA, risk free for the baby and the mother, only blood will be drawn to us. Its not a matter of mistress or whatsoever its just the baby itself I wanted to know immed. because her BF and me won't support her because. he also knew now about our relationship and of course if its my baby I have to support it, but if not then let the BF do the support, anyway please advise if this method is true and accurate...

DoulaLC · Jan 21, 2014, 05:47 PM

Yes... if you go to a reputable facility you can be assured of quality control and accuracy. It can be quite expensive however.

J_9 · Jan 21, 2014, 05:50 PM

It will be very expensive. You also need to find out if this will be recognized by your local court system. If not you will be out of a lot of money.

kojack0621 · Jan 21, 2014, 05:53 PM

Hi Friends thanks for helping me out here is the details of the facility, can you please help if you heard of them?

Q. How early can I order testing? What happens if I order earlier than this?
A. Testing can be ordered as early as 9 weeks gestation. If testing is ordered earlier than 9 weeks there is a chance that there will not be a high enough fraction of fetal DNA in the maternal plasma – in this instance DDC will request a redraw and will not issue a report."

Q. When will I get results?
A. Within 2 weeks from the time the samples are received in the laboratory in San Carlos, CA. All kits have priority shipping stickers for the sample to be returned to the testing laboratory. Blood drawn on a Saturday should be stored at room temperature until a pickup can be scheduled by courier on Monday morning."

Q. Where is the actual analysis performed?
A. All samples are analyzed at Nateraʼs CLIA-certified laboratory in San Carlos, CA. "
Q. What is required to perform testing?
A. A blood draw from the mother and from all alleged fathers, and completed consent forms. "

Q. Can I store blood samples before sending to Natera?
A. "If necessary, blood can be stored for 2-3 days at room temperature. DO NOT REFRIGERATE OR FREEZE BLOOD, as this will cause degradation within motherʼs blood cells and will result in lower fraction of fetal DNA. "

Q. Why is DDCʼs testing available at 9 weeks when other paternity tests require at least 13 weeks gestation?
A. The challenge is that there is so much less fetal DNA in motherʼs blood at 9 weeks vs. 13 weeks, which makes it much harder to read. To solve this problem, Natera leverages their proprietary bionformatics technology (Parental SupportTM) – this technology combines advanced algorithms, information found in the maternal and paternal blood, and data from the Human Genome Project to allow an accurate analysis with much lower fraction of fetal DNA. "

Q. Is there any published literature about your testing?
A. In early October Natera published an abstract at the 2011 International Symposium on Human Identification (ISHI)
Titled “Non-invasive prenatal paternity testing using fetal cell free DNA from maternal blood.”

Q. I have heard of other companies (like DNAPlus) that use technology analyzing whole fetal cells in paternity testing– why does you use cell free fetal DNA?
A. Whole fetal cells can persist in a mothers blood stream for decades after a pregnancy. If the patient in question has ever been pregnant there is a risk that using a technology analyzing whole fetal cells will give a misdiagnosis due because of this. Nateraʼs technology uses cell free fetal DNA which is cleared from a motherʼs blood stream within hours after a pregnancy, whether the termination point was delivery or miscarriage.

Q. I have also heard of a few companies that use STR (short tandem repeat) technology – why do you use SNP (single nucelotide polymorphisms) and how does it compare?
A. STR based tests measure areas of the genome where the number of copies of genetic code vary from person to person. When used on long strains of DNA, STR can be effective. Due to the highly fragmented nature of cell free fetal DNA (most of this DNA is in short pieces), STR becomes ineffective when applied to prenatal paternity testing that uses fetal DNA in maternal blood. In contrast, Natera analyzes each sample using a microarray with >300K individual genetic markers called SNPs. By analyzing this many SNPs Natera is able to create an accurate genetic blueprint of the sample which is then used to identify or exclude paternity.

Q. Can testing can be performed on twins or multiple gestation pregnancies?
A. No, testing cannot be performed on a mother that is pregnant with twins or multiple fetuses. In the case of fraternal or identical twins, or multiple gestation pregnancies, accuracy of the test results will be affected. In addition, in the case of twins by different fathers (heteropaternal superfecundation [HS]), accuracy rates of paternity testing are unknown at this time. The frequency of HS in pregnancies is suspected to be <.01%.*

DoulaLC · Jan 21, 2014, 06:09 PM

Yes... DDC is one of the more well known facilities. As J_9 said, you would want one that can be recognized by the court system. They would be able to help you through the process.

kojack0621 · Jan 21, 2014, 06:16 PM

OK thank you very much for the info...

J_9 · Jan 21, 2014, 06:22 PM

Check with your local family court to see if DDC is recognized in your area for this type of testing. It is possible that your local jurisdiction may require more accurate testing after the baby is born. If that is the case in your area, this would be a waste of money.

ScottGem · Jan 21, 2014, 06:24 PM

It is accurate, but I don't think its as safe as made out. Also, the mother has to agree to it. I doubt if a court will order it. Also you have to find a doctor who will do it.

kojack0621 · Jan 26, 2014, 04:52 PM

I'm still having a problem, the girl insists that am the father of the child and she said no need to do the DNA tesing as she knows better, can it be true? That she knew better the father of the baby even though of the below scenario?
I had sex with my mistress last Nov. 20 and Nov. 21 but she also had regular sex with her Bf every week aside from the date we had sex. Now we had an ultra sound results that said on Jan. 03, 2014 she is 7 weeks and 2 days pregnant. Who do you think is the father of the baby? By the way her LMP is Nov. 13, 2013.

No, that is not true. Get a court ordered DNA test after the baby is born to protect your interests.

ScottGem · Jan 26, 2014, 05:16 PM

As was said originally, The dates are too close to tell. So whatever the mother thinks, there is no way for her to be 100% sure.

But like I also said, she has to be a willing participant for pre birth DNA testing. If she refuses, there is nothing you can do but wait until the child is born and then go to court to request a DNA test.
