How 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. Please take care of yourself. ...Read more
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?
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
Can you use ultrasound to help determine paternity if sexual encounters are a month (30+) days apart?
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?
I'm trying to determine if guy a or guy b is the father of baby born 3/26/. My lmp was June 25th and have only had sex with guy b since June 15th.
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
Not likely: If you believe that you have received an incorrect test result, have a second test performed for verification. Whenever possible, get a second opinion. ...Read more
Before/after birth: Non invasive paternity testing (NIPP) is a technology based on detection of fetal cells in the mother's blood. A variety of specialty labs offer this service and cite the ability to find such results as early as 8 weeks into the pregnancy. Otherwise the baby can be tested at or soon after birth from a direct sample. ...Read more
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
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
Ask your lab: The lab you work with may have specific instructions on obtaining samples & it is best to follow their instructions. I see no reason a newborn could not provide a sample adequate for their needs. ...Read more
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
Depends: If you want it Legal - then you should contact a lawyer - if you want just medical - then there are paternity tests online ...Read more
Is the non invasive prenatal paternity bloodtest from natera reliable? I did the test. 1 man was an inclusion, 1 indeterminate. Is it accurate?
Not in your case: If the test results for you were "indeterminate" then that means you will not be able to draw any conclusions from those results. ...Read more
NIPP: Non invasive paternity testing is a technology based on detection of fetal cells in the mother's blood. A variety of specialty labs offer this service and cite the ability to find such results as early as 8 weeks into the pregnancy. Traditional testing requires fetal cells from invasive procedures like sampling amniotic fluid by needle or the placental cells. ...Read more
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. If the tested man cannot be excluded, a probability of paternity is issued. A paternity test can exclude someone from being the biological father with a 0% probability of paternity, if there are at least 3 genetic markers that are not shared. ...Read more
Blood was mixed up. But more likely to show negative.
Someone bribed the person doing the test. ...Read more
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
Paternity: Paternity testing is a genetic test while an ultrasound is a visual test and provides no genetic information. ...Read more
Several: The presumed father can provide DNA through a blood sample or cheek swab. The only non-invasive, and thus, safest, way to get a sample from the baby before birth is from a blood sample of the mother. The baby's DNA is present in varying amounts beginning as early as the 8th week of pregnancy. Google The American Pregnancy Association for more info. ...Read more
