How far apart do 2 sexual encounters have to be to determine paternity?

Even if...: .... The encounters were the same day, you can always determine paternity with a paternity test later. Of bigger concern: multiple unprotected sexual encounters leave you at risk for a variety of sexually transmitted diseases that can hurt both you and your baby.

How is paternity of a child determined ruled out by blood type analysis?

There are some...: ...Impossible outcomes: for example, an ab father cannot have a type o child, and vice versa. If mother's type is known, more combinations become impossible: a+o or a+a cannot yield a b or ab; o+o can only yield o, etc. ...Read more

Can paternity be determine and a correct conception date is sex between 2 different men are 5/6 days apart?

Can paternity be determine and a correct conception date is sex between 2 different men are 5/6 days apart?

Difficult to do: It is difficult to get conception dates accurate within only 5-6 days. Dates are usually accurate within 2 wks with good ultrasound and menstrual history. (Women who have irregular menses are a little more difficult to get accurate dates). In regards to paternity testing, you would need to get a DNA sample of both men and compare it to the DNA of the baby. ...Read more

Is 13 days enough time span to determine paternity LMP 3/28/14 regular cycle u/s on 6/3 for 8w1d & on 6/16 for 9w5d (different place) sex 4/3 4/16-24?

Is 13 days enough time span to determine paternity LMP 3/28/14 regular cycle u/s on 6/3 for 8w1d & on 6/16 for 9w5d (different place) sex 4/3 4/16-24?

No: In order to determine paternity, you would need DNA sample for the child (not likely until the child is born) and from the person you suspect is the father. I do not know of a way to test prior to this. The roughly 2 weeks difference in sex with different partners (?) also makes it too close to call. Your US dates are not exact and have error of up to about a week at that gestation. Sorry; ...Read more

If there is a month between sexual encounters, as well as a period, is a paternity test necessary? Edd was determined by multiple 1st tri ultrasounds.

If there is a month between sexual encounters, as well as a period, is a paternity test necessary? Edd was determined by multiple 1st tri ultrasounds.

Depends: The impact of the information often drives the need for a confirmatory study. If it was just for peace of mind, it would be considered unnecessary. If it is shadowed by legal issues like parental rights/ child support/ suspicions about the outcome, etc. It can be needed. The fact that it is available and definitive is often why it is used. Most hospitals have a the number for a lab that does it. ...Read more

2 sexual encounters 2 weeks apart! 1 protected with condom, 1 unprotected! Should dating scan help determine paternity?

2 sexual encounters 2 weeks apart! 1 protected with condom, 1 unprotected! Should dating scan help determine paternity?

I would say the: Father is the one who did not use the condom. As far as ultrasound they are too close together to use it as the determinant. Ultimately genetic testing can resolve the issue after the baby is born. ...Read more

How soon can you get a paternity test done?

How soon can you get a paternity test done?

After birth: This can be done on cells obtained from the womb by amniocentesis or from the placenta by cvs. Both procedures have some risk to mom and baby and paternity issues are not considered worthy of the risk. As soon as the kid is born, material can be obtained & sent. There are several commercial labs that do this and the hospital should have a number for information. It is not covered by insurance. ...Read more

Is there a paternity test that can be performed prenatally?

Yes: There is a non-invasive paternity blood test that analyizes fetal dna circulating in the mother’s blood. The baby’s dna is then compared to the dna taken (by buccal swab) from the potential father. This test can be performed as early as 10 weeks into the pregnancy. I highly recommend labtest md for testing. They have several locations. Www. Labtestmd. Com. ...Read more

Is it possible to get a paternity test before the child is born?

With significnt risk: Dna can be obtained prior to birth by inserting a needle in the bag of waters & withdrawing fetal cells for study. There are some medical reasons for this procedure that make the risks worth taking. However, curiosity about paternity is not one of them. The procedure carries some risk of infection or injury to both mother & child & rarely causes death. ...Read more

Is there anything that can affect the results of a paternity test?

Is there anything that can affect the results of a paternity test?

Not much.: Telling which of two identical twins is the father is a challenge, of course; also, "mosaicism" - having 2 different genetic populations of cells in one body - is possible; a sperm could come from one population, and the tested cell from another. And there is also mishandling a specimen. ...Read more

What is the definition or description of: paternity testing?

See below: Paternity testing: a test, particularly of dna or genetic traits, to determine if a given man can be excluded as the biological father of a given child.

Is there a noninvasive prenatal paternity testing company that is credible?

Unlikely: The key words of your question are credible and non-invasive. There are reports of maternal blood being used for screening, yet this technology is far from being accepted in court. Samples of the fetal membranes (cvs) or amniocentesis are accepted methods, but both pose some risk to mother and baby. Most paternity issues are handled by off site labs, hospitals or patients can obtain the test kits. ...Read more

Got two men tested for paternity test on my bby. I only slept with those two about two or three weeks apart. Both test came back negative how is that?

Impossible...: If you only had sex with two men, then one of them is the father. Either there was a "testing error" (labs are reliable, if they got the correct specimen this is very unlikely), one of the two men didn't actually get tested, or you have forgotten about another possible father. Good luck. ...Read more
