Paternity testing, blood types, and DNA

Specialties Ob/Gyn

Published

I hope someone can give me some answers about DNA testing. My daughter had a baby in August. The "father" wanted blood testing done because it is a cheaper way to go than the DNA. MOM-type 0, DAD type O, BABY type B.

I looked on the internet several times to find info because "he" said he couldn't be the father because two "o's" can't make a "b".

Being the strong-willed person I am, I insisted he have the DNA last month, regardless of his belly-aching that it was a waste of time.

Well, low and behold, the DNA test came back yesterday and he is 99.99% my grandsons father. He matched on every one.

Am I just confused about the blood typing or is it a fluke? He brought his results over to prove his type, but the DNA is the final word!!

This is interesting, I would say the the Father is probably pulling your chain with the paper stating he is type O. Especially since the DNA test confirmed he was in fact the father.

I am always leery of these guys who want paternity testing........I know this is off the subject, but your daughter needs to watch her back. Any guy (in my opinion) that wants to opt out and say he isn't the father of the baby is cause for concern!

I totally agree. The problem was that they had broken up before she knew she was pregnant and he has another "girlfriend" now.

He is being very cordial about it since the tests came back, though.

He was just hoping you'd let him off the hook when he told you he had type O. But in his defense, maybe he really thought he had O...we tested our blood types in high school science class and got some wrong results as the test kits were not high calibre.

Hope everything goes well with your daughter and that they boy helps with support. :)

Isn't DNA testing expensive? On the rare occasion that we have a father that wants it we indicate that it can run thousands of dollars and then it's also expensive to change the birth certificate if he's already signed it. We always refuse to do it (in our NICU) because we don't want to deal with the whole chain of custody thing.

Around here tsting is not readily available until the baby is about 6 months old, so i am told.

We didn't have to pay the cost of the DNA testing. It was $50 dollars for each of them. They all three were tested. He paid the $150.

Interesting that there are "high caliber" testing and getting wrong results.

Thanks for all your opinions. I have wondered for a while about whether or not there was a possibility that he was right about not being the father because of his blood type. I thought there was something fishy!

What a relief to finally know!!

Oh, by the way, he hadn't signed the birth certificate. When she picked up the birth certificate, they told her, because the DNA tests were pending, that she just needed to bring it back with her receipt and they would add the father.

They did mouth swabs on them for the testing. I am told that they can even do DNA testing while the baby in still in the womb. Amazing, isn't it?

Got an update for y'all!! Ryan now says that he thinks the person who obtained the DNA swabs mixed his up some how and that is why he came back as being positive. He is now insisting that a repeat DNA be done except he wants blood drawn this time (in more ways than one, I think!) So now they are going to go through this again!

He says that a buccal swab is not as accurate as the blood.

Anyways, rumor has it that the private testing is $450 per person. If he wants to do that, I'm afraid he will have to come up with some money!

Just wanted to fill you in on the latest.

Hope your New Year starts out great!

Tell your daughter to refuse to have the testing done. I speak from personal experience when I say that she doesn't want this "man" in her life for the next 18 years. Just let the issue go, no amount of child support is worth putting up with an unwilling father, she will probably eventually meet the man she wants to spend her life with and it will be a lot less hassle for her if she doesn't have to deal with Ryan. I have done this, been there. and am currently living through hell over it. I have been in and out of court with my dd's father 6 times in the last 7 years over custody, the court has ordered that I cannot move out of the state with my minor daughter without losing custody, so I am stuck in a area with NO jobs, she will probably also have trouble collecting child support from him if he is willing to go through all of this just to be "proven" not the father. It is too much hassle, and your grandchild will suffer, your daughter will suffer and this joker will still be untouched b/c if he cared at all he wouldn't be doing all of this, there is NO reason to force him to be a father other than support and trust me it aint worth it. JMHO. I wish someone had given me this advice.

Wow, that's some amazing mix-up--the lab must have just happened to have a swab from the "real father" on hand if the test came back positive. :rotfl: If he wants to have a repeat done, he has to fork out the $$.

It's too bad that he seems to be in denial; however, I think that insisting on paternity testing is a wise thing to do in cases like this. If my son were to father a baby before marriage, I would advise him to confirm paternity before signing the birth certificate. If, later on, it turns out that he isn't the father--it doesn't matter in the eyes of the court. He would still be on the hook for child support until the child turned 18.
