What Can Go Wrong With The Prenatal Paternity Test
The test consist of a simple blood draw from each person and is considered safe and non-invasive. In most cases the tested persons will receive their results after the first try. On some rare occasions, there might not be enough DNA the first time. This is in no way an indication that there is something wrong with the baby. The amount of fetal DNA in the mothers blood is known to vary during the day. If there is insufficient DNA the first time, additional recollections are provided free of charge. Please note that at the 9th week of pregnancy, only 10% of mothers require recollection. The percentage of mothers needing a recollection goes down as the pregnancy progresses. Therefore rest assured that recollection is only rarely needed.
How Is Cvs Performed
CVS may be offered to women with an increased risk of chromosomal abnormalities or who have a family history of a genetic defect that is testable from the placental tissue. CVS is usually performed between the 10th and 13th week of pregnancy. Although exact methods may vary, the procedure involves the following steps:
Your doctor will insert a small tube through your vagina and into your cervix.
Using ultrasound technology, your doctor will guide the catheter into place near the placenta.
Your doctor will remove some tissue using a syringe on the other end of the catheter.
Your doctor may also choose to perform a transabdominal CVS, which involves inserting a needle through your abdomen and into your uterus to sample the placental cells. You may feel some cramping during and after either type of CVS procedure. The tissue samples are sent to a genetic lab for growth and analysis. Results are usually available in about 10 days to two weeks, depending on the lab.
Paternity Testing At The Time Of Birth
If you are in a hurry to know the paternity of your child, you can also consider testing the child at the time of delivery using umbilical cord blood, which will pose no risk to the child. Paternity testers will be able to provide results 3 to 5 working days after the samples are collected. If you would like to test the child at the time of delivery, please contact the paternity testers in advance to arrange for testing and to have an umbilical cord blood collection kit forwarded to your physician before the due date or to you for you to take to the hospital when giving birth.
Results are usually available within 3 to 7 days.

Other Types Of Dna Tests That Can Be Done During Pregnancy
If you are pregnant then genetic testing can be a useful tool, not only for determining paternity, but also to discover if your baby is at risk of carrying genetic diseases. For a long time, pregnancy testing such as amniocentesis and Chorionic Villus Sampling were used but those tests are quite invasive and carry a risk of potential miscarriage or harm to the baby.
DNA tests that can be used to alert the parents-to-be of genetic abnormalities are generally done with blood tests and an ultrasound between 10 and 13 weeks. With another genetic marker scan and DNA test available to parents between 15 and 20 weeks.
These tests are referred to as NIPT or non-invasive prenatal tests or NIPD .
NIPT can be used to test for altered genes, the gender of the baby and can detect Down Syndrome and other conditions. This is a non-invasive test because it uses a drop of blood from the mother and uses free cells that can be found in her bloodstream. It doesnt rely on the cells found in the amniotic fluid like amniocentesis or CVS.
Now that DNA testing is more accessible to consumers through a wide variety of companies mothers-to-be have the option to learn a lot of important information about their baby before the child is born.
When Can You Get A Dna Test During Pregnancy
By | Submitted On May 30, 2008
The DNA of the child has many clues as to what information the child will be born with. These clues can be uncovered and the information extracted by performing a DNA test during pregnancy. Advancement of technology has enabled to get a child’s DNA tested even before the child is born.
A DNA test is done during pregnancy to test the DNA of the unborn child. Amongst the many reasons as to why a DNA test of the unborn child may be required is testing the paternity of the child. Other reasons include testing for abnormalities and inherited genetic diseases.
A DNA test of the unborn child can be done during pregnancy during the period between 10 to 24 weeks after conception. The method of sample collection is different for different ages of the developing baby.
If your pregnancy is between 10 to 13 weeks after conception, the method used to collect the sample for DNA Testing is chorionic villus sampling. In this procedure your doctor will insert a thin needle or a fine tube guided by ultrasound, into the womb through the vagina and cervix to obtain a sample of chorionic villi. The sample obtained will then be tested and analyzed.
If you are more then 24 weeks pregnant, the risk of damaging your unborn baby while collecting the sample for testing is significant. So, doctors advise to stay till your baby is born to get the test done. After the birth of your baby, several methods can be used to take a sample from the baby.

What If Cvs Is Not Possible
Women with twins or other higher-order multiples usually need sampling from each placenta. However, because of the complexity of the procedure and the positioning of the placentas, CVS is not always feasible or successful with multiples.
Women who are not candidates for CVS or who did not get accurate results from the procedure may require a follow-up amniocentesis. An active vaginal infection, such as herpes or gonorrhea, will prohibit the procedure. In other cases, the doctor may take a sample that does not have enough tissue to grow in the lab, generating incomplete or inconclusive results.
Paternity Testing: What Are My Options
Paternity tests can be performed during or after a pregnancy. Postnatal tests, or those done after a baby is born, can be completed through an umbilical cord collection after delivery. They can also be performed by a cheek swab or blood sample taken at a lab after the baby has left the hospital.
Waiting to establish paternity until delivery, while ensuring accurate results, may be difficult for you and the alleged father. There are several paternity tests that can be conducted during pregnancy.

Second Trimester Prenatal Screening Tests
Second trimester prenatal screening may include several blood tests called multiple markers. These markers provide information about your potential risk of having a baby with certain genetic conditions or birth defects. Screening is usually done by taking a sample of your blood between 15 and 20 weeks of pregnancy . The multiple markers include:
AFP screening. Also called maternal serum AFP, this blood test measures the level of AFP in your blood during pregnancy. AFP is a protein normally produced by the fetal liver that is present in the fluid surrounding the fetus . It crosses the placenta and enters your blood. Abnormal levels of AFP may indicate:
A miscalculated due date, as the levels vary throughout pregnancy
Defects in the abdominal wall of the fetus
Down syndrome or other chromosomal abnormalities
Open neural tube defects, such as spina bifida
Estriol. This is a hormone produced by the placenta. It can be measured in maternal blood or urine to be used to determine fetal health.
Inhibin. This is a hormone produced by the placenta.
Human chorionic gonadotropin. This is also a hormone produced by the placenta.
Abnormal test results of AFP and other markers may mean that additional testing is needed. An ultrasound is used to confirm the milestones of your pregnancy and to check the fetal spine and other body parts for defects. An amniocentesis may be needed for an accurate diagnosis.

How Much Does It Cost
The cost of a paternity test varies according to the nature of the test and the time of its occurrence. Normally the price ranges from $400 to $500 per test. Even a pre-birth paternity test aided with the highest and most advanced technological interventions should not exceed the cost of $550 per test.
In case it is a court ordered paternity test then the price is a bit lower. Courts normally assign a contract DNA paternity test facility and the parents along with the child need to go specifically to that facility in order to conduct the test.
In some cases if the first paternity test fails to provide conclusive results a further test can be ordered by the court. The price of such tests can be a bit expensive. If the fetus is still in the womb of the mother the OB-GYN can order an invasive paternity test like in the form of amniocentesis and chorionic villus sampling. The costs of such tests are usually much higher than the regular cheek swab tests. But it is safe to say that most of the cheek swab or regular sample collection DNA paternity tests provide fairly accurate results.
Unless it is not absolutely necessary then it is not wise to go for the invasive DNA paternity tests. They post much risk to your child.
The non-invasive test is safe and also prompt when compared to the other pre-birth DNA tests. 8 weeks is the soonest a father can know whether the child is his or not.
What Goes On During A Paternity Test
A paternity test can only proceed after taking legal consent from all the involved parties. There is a load of paperwork that needs to be conducted. After the papers are signed and the payment is being made, the paternity test proceeds.
The nature of the sample collection depends mostly on the type of paternity test ordered. Barring the non-invasive and invasive tests mentioned above other simpler tests can be conducted once the baby is born.
One of the easiest and the least expensive method is taking cheek swabs from the child, the father, and the mother. The swabs are kept in three separate sterile bags ready for DNA extraction. The actual paternity test needs around 3 days to conclude.
However, if it is a court ordered paternity test then in that case the results can only be provided to the court and the concerned parties can only get the results after lots of legal paper-works.

How Does A Prenatal Paternity Test Work
A prenatal DNA test requires samples from the pregnant mother and possible father. First, a blood sample will be drawn from the mother, while a cheek swab will be collected from the potential father. Because fetal DNA floats freely in the mothers blood, the lab will then be able to build a DNA profile for the unborn child using the collected sample. This profile is compared to the fathers DNA profile, and probability of paternity will then be established.
The Position Of The Canadian Children’s Rights Council
Don’t be too quick to judge the sexual conduct of these men and women. The men and the woman may not have made representations that they were in a monogamous relationship. The position of the Canadian Children’s Rights Council is that children’s identity rights should be provided expeditiously at or before birth as soon as technologically feasible by non-invasive means. See our section on why we advocate for mandatory paternity testing as soon as available after birth or even before birth when non-invasive prenatal DNA paternity testing is widely available. We advocate for such testing to be paid for by government health insurance plans for everyone.

Who Knows Father Best
Feminist organizations including the National Organization of Women has objected to legislation that requires the courts to vacate paternity judgments against men who arent, in fact, the father.
Think about that. NOW wants some man, any man, to make child support payments. The woman who doesnt even know who the father is, should not be held responsible for her actions, is a sweet, loving, blameless mother who seeks only to care for her child and if naming some schmuck as father who never saw her before in his life helps her provide for the innocent babe, well then, that’s fine.
Innocence is no excuse. Pay up. Read More ..
When To Get Nipt
NIPT can be done at various stages in the pregnancy, as shown in the Prenatal Screening Pathway.
- Some pregnant individuals will have NIPT as the first prenatal genetic screen in their pregnancy, and it can be done as early as 9 or 10 weeks gestation depending on the lab. A nuchal translucency ultrasound in the first trimester can still be performed to provide additional information about the health of the baby.
- Other pregnant individuals will start with a traditional screening test and then may decide to have NIPT if the traditional screening reports a positive result, or if there are concerns on one of the ultrasounds.

Are There Any Other Paternity Tests
DNA Worldwide also provide a prenatal CVS/Amnio DNA paternity test, however in some cases this test cannot begin until the mother is 16 weeks pregnant, this is when amniocentesis can be carried out by our approved clinic. The reason for this is because the position of the placenta is not in its normal natural position and cannot be accessed safely.
The clinic that collects CVS/Amnio samples for paternity testing is the leading clinic in the country and is based in London. Before the appointment we ask that the mothers blood type to be provided to the specialists at the clinic. Other items such as two passport photos and a photo ID must be provided by each person attending the appointment at the clinic.
If both prenatal paternity tests aren’t an option, the next step is to wait until the child is born and order a mouth swab paternity test. This paternity test needs mouth swabs to be taken from the participants and sent to our laboratory. A sample can be taken from the child within an hour of their birth. Results can be expected within 3-5 business days and you can expect a conclusive result.
Which Ultrasound Imaging Techniques Are Available
There are several types of ultrasound imaging techniques. As the most common type, the 2-D ultrasound provides a flat picture of one aspect of the baby.
If more information is needed, a 3-D ultrasound exam can be done. This technique, which provides a 3-D picture, requires a special machine and special training. The 3-D image allows the health care provider to see the width, height and depth of the images, which can be helpful during the diagnosis. The 3-D images can also be captured and saved for later review.
The latest technology is 4-D ultrasound, which allows the health care provider to visualize the unborn baby moving in real time. With 4-D imaging, a three-dimensional image is continuously updated, providing a live action view. These images often have a golden color, which helps show shadows and highlights.
Ultrasound images may be captured in still photographs or on video to document findings.

Where Can I Get A Paternity Test While Pregnant
Expectant mothers can discuss the question of paternity with their Ob/Gyn during their prenatal appointments. The Ob/Gyn can then discuss all of the options for paternity testing during pregnancy with the mom-to-be and can organize when and which type of prenatal test the mother wishes to have done.
Amniocentesis and Chronic Villus Sampling tests will need to be performed by a physician. It is important to note that these tests when performed for paternity purposes are rarely covered by health insurance and are often expensive.
In certain situations, these tests may not be performed without a court order and there are important legal paperwork and consent forms that will need to be signed.
Invasive prenatal paternity testing can only be performed by a qualified health professional, unlike the noninvasive method of DNA testing which can be done from home.
Moms-to-be wanting a NIPP test can use companies like DNA Diagnostics Center to collect the DNA samples and perform the test for paternity.
DNA Diagnostics Center schedules the sample collection at a local facility, the samples are then sent for analysis, and results can be expected back within 7 working days or less.
Alphabiolabs is another company that performs NIPP tests, promising DNA results will be received within 7 working days.
For parents seeking extra peace of mind about the analysis of their DNA samples, a list of labs that are accredited by the AABB can be found on the AABB website.
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.
For prenatal sex tests, we recommend International Biosciences. Other testing providers can be found here.
