How Do Paternity Tests Work
“For a paternity test, what is usually used is called Short Tandem Repeat, or STR tests,” says Arnab Chowdry, biophysicist and VP of Genetic Technology for 23andMe.
Chowdry explains that STRs are long regions in the human genome composed of short segments, typically two to four letters long, that just repeat over and over. Because these regions mutate from time to time, they vary widely in length from person to person.
In a way, they can act as a “genetic fingerprint,” because every person is going to have the same STR segments, but the combination of STR lengths a person inherits will be unique. More importantly, because 50% of a childs DNA comes from their father, roughly 50% of these STRs should be shared between them.
Next these segments are measured by using a process called Polymerase Chain Reaction, or PCR . This is a process that geneticists use to “amplify” specific regions of DNA. In the case of paternity tests, certain STR regions are copied over and over again.
Think about how rocks of various weights might behave on the bed of a fast-flowing stream. The smaller and lighter rocks will be pushed farther and faster than the bigger and heavier ones. The same goes for longer and shorter STRs. Once the STRs are separated, the patterns from the child can be matched to patterns seen in their potential parents.
Can You Determine The Father Of An Unborn Child
A DNA paternity test is nearly 100% accurate at determining whether a man is another persons biological father. DNA tests can use cheek swabs or blood tests. You must have the test done in a medical setting if you need results for legal reasons. Prenatal paternity tests can determine fatherhood during pregnancy.

The Ins And Outs Of The New Paternity Test During Pregnancy
12 Aug 2017
Paternity testing during pregnancy has finally taken a step ahead. Only a few years back it was only possible to do through invasive procedures done by the gynaecologist. The two main invasive procedures were called CVS and amniocentesis. Fetal DNA cells would be collected by entering the womb with instrumentation or by using a syringe on the tummy. In fact the fetal DNA samples that would normally be collected are called the amniotic fluid or the Chorionic Villi. There was no other way fetal DNA of the unborn child could be collected in order to carry out a paternity test.
These procedures continue to be uncomfortable and could possibly even lead to bleeding or a miscarriage even though they havent been improved over the years. With the giant leap science has now taken in this field one should definitely consider new the non-invasive procedures.

Dna Paternity & Gender Testing While Pregnant
Discovering the paternity and gender of a baby before birth is a common wish among women. Paternity questions can add stressbut there is a safe solution. Our technologically advanced Non-Invasive Prenatal Paternity Testing makes it possible to get accurate answers early in a pregnancy without risk to the baby because we only use blood collected from the mother. Cells from the developing fetus float freely in the bloodstream of the pregnant mother. These fetal cells can be found as early as the 7th week of pregnancy. We develop a DNA profile of the fetal cells and compare the profile to the DNA profile of the presumed father as well as identify baby gender if requested.
We proudly offer the most accurate and scientifically substantiated way to establish paternity and gender before the baby is born. The process is state-of-the-art, combining the latest in DNA SNP technology and patented methods of preserving and analyzing the babys DNA found naturally in the mothers bloodstream.
Can A Test Determine Paternity During Pregnancy
There are three different ways to test paternity before a baby is born. The tests are as accurate as those performed after a childs birth. The three methods include:
- Noninvasive prenatal paternity test : This test analyzes fetal DNA found in a pregnant womans blood during the first trimester. A lab specialist compares the fetal DNA information to DNA from the potential fathers cheek cell sample.
- Chorionic villus sampling : A healthcare provider takes a small sample of tissue from the placenta. This procedure takes place through the mothers cervix or abdomen. A lab compares DNA from the sample to the mothers and potential fathers DNA. CVS typically takes place between 10 to 13 weeks after a womans last menstrual period. The procedure carries a slight risk of miscarriage or pregnancy loss.
- Amniocentesis: During amniocentesis, a healthcare provider draws out a small amount of amniotic fluid. The test uses a needle inserted into the mothers abdomen. A lab compares the fluid sample to DNA from the mother and potential father. Amniocentesis takes place between the 15th and 20th weeks of pregnancy. The test slightly increases the risk of miscarriage.

Paternity Testing Before Birth
If you have any questions about who the baby’s father is then the most reliable paternity test method is testing for DNA which can be done as prenatal paternity testing either during pregnancy or after delivery of the baby.
DNA stands for “deoxyribonucleic acid” which is a material present in nearly all living organisms as the main constituent of chromosomes, carriers of genetic information that are found in the nucleus of most living cells.
In the past, DNA-based paternity tests were only available after delivery from tissue or blood collected from the baby and the alleged father. Or invasive tests had to be done during pregnancy potentially risking the baby’s life. It is now possible to do paternity testing during pregnancy and prior to birth with a simple non-invasive blood test from the mother and a DNA test from the father. This makes it possible to do fetal DNA testing from the mother’s blood as early as 8-9 weeks in pregnancy without risk to the baby because only blood is collected from the mother without the need for an invasive test.
Since cells from the fetus float freely in the bloodstream of the pregnant mother as early as 8 weeks of the pregnancy, paternity testing companies can develop a DNA profile of the fetal cells and compare the profile to the DNA profile of the presumed father. A conclusive paternity test report can be delivered in as little as 3 business days after both DNA samples have been received, but the supposed father has to be tested too..
How Long Do The Non
The test results will usually take 14 days to be received by Ultrasound Care and for you to be informed. On occasion, there is not enough cell-free DNA from the pregnancy in the sample so blood recollection may be required in this case the results will take another 14 days to be received but you will not have to pay for the second test.

Learn More About Paternity Test
A paternity DNA test determines the biological father of a child. We all inherit our DNA from our biological parents, half from our mother and a half from our father. A paternity test compares a childs DNA pattern with that of an alleged father to determine if there is a match. When performed correctly in an experienced laboratory, its the most definitive proof of a biological relationship.
Paternity testing is the most accurate method to know today to confirm or dispel doubts about a biological relationship between two or more persons. There are many reasons why a paternity test may be required these may include medical legal or even personal reasons.

Get Your Dna Collected
Show up to your scheduled DNA collection time at our main laboratory location in El Paso, TX. Make sure to bring a federally recognized government ID, such as a drivers license, passport, or military ID. If having a legal test completed you may also be required to have a picture taken by the collector . The collector will help you fill out the paperwork, make a copy of your ID , sign the consent forms, and certify that the collection has taken place according to all AABB and legal standards.
The potential father must provide a DNA sample at the same time as the mother, as the blood sample must be processed ASAP.
If you are having a Legal test performed, the potential father must be present with an ID while giving a his own DNA sample.

Choosing The Right Dna Testing Lab Is A Must
Due to the fact that even the cheapest NIPP test out there can cost so much more than the usual paternity as well as ancestry testing, it can be very tempting to grab the NIPP test with an incredibly low price.
However, its of utmost importance to look at not only the cost but also the credibility of the lab offering the test.
Since the popularity of online DNA tests, countless of testing laboratories have come into being. It can be very tempting to open up a laboratory these days especially because it is estimated that at the start of 2019 over 26 million people have undergone at-home DNA testing and that only accounts for those who wish to learn about their ancestors!
Certainly, not all DNA laboratory testing facilities are cut from the same cloth sealing the deal with an unreliable company is money flushed down the drain.
According to the American Pregnancy Association, its a good idea to go for DNA labs that are accredited by the American Association of Blood Banks .
As a general rule of thumb, the most reliable facilities out there are those that have been operating for years now and endorsed by reputable health-related agencies or organizations.
How long will it take before I get my hands on NIPP test results? Usually, it takes about 8 to 14 days before the results become available. If an online DNA laboratory is the one doing the testing, shipping then becomes a factor.
Are Dna Paternity Tests Safe
Noninvasive prenatal paternity tests are considered by experts to be highly accurate and completely safe for both the pregnant parent and baby.
Amniocentesis and chorionic villus sampling are invasive paternity tests that carry more risks. Unless theyre needed to diagnose a severe genetic disorder, they are not usually recommended by health care providers.
Potential risks of chorionic villus sampling include:
- Miscarriage: There is an estimated 0.22 percent chance of miscarriage with CVS.
- Infection: In rare cases, CVS can trigger an infection in the uterus.
- Rh sensitization: CVS can make some of your babys blood enter your bloodstream, which can damage the babys red blood cells. If you have Rh-negative blood and dont have antibodies to Rh-positive blood, youll be injected with Rh immune globulin to stop your body from producing Rh antibodies that can harm the baby.
Additionally, if you have any of the following conditions, your health care provider may recommend avoiding CVS:
- An active infection in the cervix or vagina
- Bleeding or spotting from the vagina in the past two weeks
- An inaccessible placenta due to a tilted uterus
- Benign growths in the cervix or lower uterus
After CVS, if you experience fluid leaking from your vagina, heavy vaginal bleeding, a fever, or contractions in your uterus, contact a health care provider right away.
Potential risks of amniocentesis can involve:

Prenatal Sex Testing / Baby Gender Testing
Unlike prenatal paternity tests, fetal sex tests can be conducted as early as seven weeks into pregnancy, measured from the Last Menstrual Period. These tests look for cell-free fetal DNA belonging to the fetus, which can be detected in the mothers blood. These tests are 95-98% accurate from 7-20 weeks, with their accuracy rising to 97-99% after 20 weeks. Usually, these tests are only offered after 10 weeks, possibly to improve the accuracy.
Often, you will not have your first ultrasound until 14 weeks into pregnancy, and so it is sometimes possible to determine your babys sex before your first ultrasound using a DNA test. These tests are not a replacement for an ultrasound test, which is important for monitoring your unborn babys health and development, and predicting your due date.
Like non-invasive prenatal paternity tests, a prenatal sex DNA test requires a blood draw taken by a trained medical professional. The blood sample taken will not be as large as for a paternity test, since less fetal DNA is needed to determine sex. Still, beware of companies that offer baby gender tests that require you to only prick your finger onto card, or draw the blood yourself. These will not yield accurate results.
