Frequently Asked Questions
about DNA paternity tesing
Home
Why is accreditation important?
DNA relationship testing is not regulated by a government agency. Accreditation
is the only safeguard a private individual has to know that a paternity testing laboratory is
performing sound and accepted scientific methodology. (New York Residents:
Accreditation is required by your state agency for all testing in New York).
Paternity Testing Corporation is accredited by the American Association of Blood
Banks, FQS/ ISO 17025 and the New York State Department of Health. Paternity
Testing Corporation also participates in proficiency multiple times per year
with the College of American Pathologists, Forensic Quality Services and the New
York Department of Health. Click here for more information on Accreditations
Why does mom need to be DNA tested (since we already know she is the mother)?
Children receive half of their DNA from their mother and half of their DNA from their father.
By comparing the mother's DNA and child's DNA we can tell which parts of the child's
DNA came from the mother, because they match exactly. This lets us know that the
remaining part of the child's DNA came from the biological father---so we know
what to compare to the tested man. But without mom, we cannot eliminate part of
the child's DNA. So even if the tested man is matching part of the child's DNA,
we don't know if he is matching parts that came from the biological father, or
from the mother. Without the mother, there is a greater chance that even if the
DNA
tested man is matching the child's DNA the matches could be random and the man
might not really be the child's biological father.
In order to ensure the accuracy of a motherless DNA paternity test, it is often necessary to
perform additional and/or more discrimination DNA testing. Paternity Testing
Corporation provides the same high guarantee on a motherless DNA paternity test as a
paternity test that
includes the mother. In order to obtain this high degree of reliability
additional DNA testing may be necessary and the paternity test may take longer.
Can a DNA paternity test be performed before the baby is born?
Yes. The mother's doctor can perform amniocentesis, to extract amniotic fluid
during pregnancy (usually after 12 weeks). The fluid is then sent to Paternity
Testing Corporation to provide the child's DNA for paternity testing.
There can be significant cost to perform the amniocentesis. More importantly,
the amniocentesis presents medical risks to the mother and the child. You should
discuss those risks with your doctor. Because of those risks, most doctors
prefer not to perform an amniocentesis unless there are medical reasons
requiring the procedure. If the mother is going to have amniocentesis for
medical reasons, then a paternity test can also easily be performed.
Another method that can be used is Chorionic Villus Sampling (CVS). This method
of testing has increased risk (including birth defects), but can be performed a
few weeks earlier than an amniocentesis. If CVS is going to be performed for
medical reasons then it can also be used for paternity testing.
Beware of claims that a prenatal paternity test can be performed by simply
taking the mother's blood for the child's DNA specimen. This is a fraudulent
claim and at this time the testing does not produce accurate or reliable
DNA paternity results.
We live in different cities. Do we all have to be tested at the same place?
There is no need for everyone to be in the same city in order to be tested. We
can have the specimens collected anywhere in the country (and most places in the
world). For example, if the mother and child live in Atlanta they would go to
DNA paternity laboratory there to have their specimens collected and if the alleged father
lives in San Francisco then he would go to a DNA paternity laboratory in San Francisco to have
his specimen collected. All 3 specimens will be shipped to our DNA paternity
testing laboratory
overnight and the paternity test will begin once we receive all specimens.
We are not giving our specimens at the same time. How do I know the right person
was DNA tested?
In addition to checking photo identification an instant photograph is taken of
everyone paternity tested. A right thumbprint is also taken on the DNA tested adults.
Occasionally an "imposter" will come in for a DNA paternity test. Most often when this occurs
the alleged father sends a friend in to have his DNA specimen taken. When this
happens the mother can look at the photograph and tell us that the man DNA tested
was not the alleged father.
Often the alleged fathers worry that even though they can identify the mother,
they may have never seen the baby or it may have been several years since they
saw the child. They want to know how we can be sure we are testing the right
child. In the case of an infant, it would not be possible for the mother to
bring in someone else's baby because the test will show that it is not her
child. In unusual cases it may be necessary to take extra precautions to ensure
that the right child is tested. It may be necessary to have the child's DNA specimen
taken in front of an attorney or doctor or other credible person who can verify
the identity of the child.
Why does the DNA paternity test take so much longer than on TV?
There are two types of television shows that portray DNA testing and neither
gives a very clear picture of what really happens.
The first type is talk shows, shows like Jerry Spinger and Montel Williams (both
of which Paternity Testing Corporation has performed DNa paternity testing for). In these
shows, it often appears that participants are DNA tested and the results seem
instantaneously available. In actually, these shows are often filmed several
days after the DNA testing specimens were collected and the results are
available prior to the filming of the show.
The second type is television drama, shows like CSI and Law and Order. These
shows often portray the collection and results of DNA evidence that is not
suitable for DNA testing as well as results in minutes from the time of
submission to the laboratory. In reality, normal STR DNA testing can be
completed in days under average circumstances and you need to ask about DNA sample
types before you submit anything to a DNA paternity testing laboratory (Example: Cut hair is not a
good sample).
Most people needing DNA testing do not have a DNA paternity testing laboratory close enough to them to
have their samples collected at the site where the DNA paternity testing will actually take place.
Therefore, the samples must be shipped by overnight courier to a DNA paternity
testing laboratory who
will begin DNA testing after they receive the samples. Sometimes this is the day
after collection or can be even later if you are collected on a Friday or late
in the day. Once the samples are received at the DNA paternity testing laboratory, DNA testing begins
and results are usually available in approximately 3 working days.
Should we have a legal or a non-legal test?
What Makes a DNA Paternity Test Admissible in Court?
To be admissible in court a DNA paternity test must meet two requirements. First,
the test must be performed by a DNA paternity testing laboratory that is accredited by the American
Association of Blood Banks (AABB).
Second, the DNA specimens used in the DNA ppaternity test must have been collected, shipped and
stored in a manner that establishes a good chain of custody for the specimens.
This allows the DNA paternity testing laboratory to prove that the individuals whose names appear on
the paternity test are truly the individuals who provided the DNA samples that
were DNA paternity tested.
The chain of custody begins with the DNA specimen collector attaching a picture of
the collected individuals to the form used to collect the DNA specimens (often
referred to as a Specimen Collection Form or Chain of Custody Form). The
DNA collector also checks a photo ID such as a driver’s license, and takes a
thumbprint of the DNA tested individuals. Additional procedures may also be
followed. The specimens must then be shipped to the paternity laboratory and
stored at the laboratory in a manner that ensures the security of the specimens.
What Makes a Paternity Test Acceptable for Other Official Purposes?
Even if you do not want to use your DNA paternity test in court, you may need it for
other official purposes. For example, you may need it in order to obtain Social
Security benefits for the child, or to have the child placed on the father’s
health insurance, or to change or add the father’s name on the child’s birth
certificate. For various agencies to accept your DNA paternity test results, the
DNA paternity test will usually need to meet the same requirements as if you were going to
have the DNA paternity test admitted in court.
Why Obtain an Official Paternity Test rather than a home paternity test?
Even if you do not intend to use your DNA paternity test in court, circumstances may
change and you may want to use it in court at a later time. Also, you may
eventually need an official paternity report for such things as health insurance
or Social Security benefits. Whenever possible, it is much better to have the
specimens collected in a way that allows the test to be used as an official
document if necessary. In that way you avoid having to pay for another DNA paternity
test whenever the need for an official DNA paternity test arises.
Is the DNA paternity test confidential? Who can get the results?
The DNA paternity test is completely confidential. The mother of the child and all adults
DNA paternity tested are entitled to receive the results of the DNA paternity test, as well as copies of the
pictures of everyone who was DNA paternity tested. The only other people who can get results
of the DNA paternity test are those designated by the DNA tested adults or a legal guardian of a
DNA tested minor child. For example, the mother and alleged father may want DNA
paternity results
sent to their attorneys.
No one else can get any information about the DNA test. They can not even find out
whether an individual was DNA paternity tested, unless we have permission from a
DNA tested
individual to give out that information. However, if Paternity Testing
Corporation receives a subpoena or court order to produce documents, we are
obligated to comply.
The mother and alleged father are not able to receive personal information about
each other. For example, Paternity Testing Corporation will not give the mother
information such as the alleged father's social security number or address.
Can the DNA paternity test give the wrong result?
Yes, the DNA test can give the wrong result. Paternity Testing Corporation takes
many extra precautions to prevent this from happening. As far as we know, we
have never given out a wrong result.
If the child and the DNA tested man do not match at three or more tested DNA
locations, then the tested man can not be the biological father of the child. If
all of the parties samples were not collected at the same time, requesting to
see the photographs of the other parties may be prudent to ensure the correct
people were DNA paternity tested.
On the other hand, when the alleged father and child have matching DNA, the
alleged father is not the only one who could be the biological father of the
child. The test only determines how likely or "probable" it is. The higher the
probability of paternity or paternity index, the more certain it is that the DNA
tested man is in fact the child's biological father.

Why does a higher probability of paternity matter?
AABB accredited laboratories are only required to DNA paternity test to a 99% probability of
paternity. A DNA paternity test at a 99% probability of paternity has identified a
DNA genetic
pattern that, on average, 1 out of every 100 men would have. Thus many people
have this same pattern and would show the same result on the DNA paternity test. At this
level of reliability a DNA paternity test would give the wrong result (a "false
positive") for 1 out of every 100 non-fathers who are DNA tested.
Paternity Testing Corporation guarantees a minimum probability of paternity of
99.99% on every DNA paternity test (motherless and mutations included). At a 99.99%
probability of paternity, on average the identified DNA genetic pattern will fit no
more than 1 in every 10,000 men. Most of our DNA paternity tests are even more discriminating
than that. Click for more information on Avoiding Erroneous Results or How to
choose a Paternity Laboratory.
Do I need to DNA paternity test both alleged fathers if they are brothers?
Yes. If there is more than one possible father of the child and the possible
fathers are closely related to each other, then it is very important to DNA test
them both. This would be true, for example, if two potential fathers are related
to each other as brothers or as father and son. The DNA paternity test of a single
alleged father only identifies a probability of paternity for that alleged
father compared to other unrelated men. If two possible fathers are closely
related, then their DNA genetic makeup can be very similar, and they could easily
both receive a positive DNA paternity test result (alleged father's that are identical twins
will either both match the child or both be excluded). Except for identical
twins, the laboratory will continue testing until one of the alleged fathers is
excluded (at no extra charge). If only one of the related alleged fathers is
available, the client can pay the laboratory to perform additional DNA paternity testing in
order to establish a likelihood that the DNA tested man is the biological father as
opposed to the unavailable relative. But it is best to DNA test all related parties
who could be the father of the child.
Is taking a DNA paternity test a good idea?
There are a wide variety of reasons to have DNA paternity testing done. Many DNA tests
are performed on newborns. Sometimes there is more than one candidate for
fatherhood. Sometimes the mother knows who the father is, but the father wants
to be sure. In other cases the parties may know who the father is, but need to
have official proof. This can happen if the parties were not married at or near
the time of the child's birth. Official proof may be required for many reasons
including health insurance, Social Security benefits, child support, child
custody, visitation, adoption, immigration or inheritance.
A DNA paternity test is not always a good idea. You should consider all of the
possible consequences before deciding to take the DNA paternity test.
For example, it sometimes happens in the heat of an argument that a mother will
tell a presumed father for the first time that he is not really the child's
father. Some men pursue a DNA paternity test to find out. But if the man loves the
child, has a good relationship with the child, and intends to continue to love
and support the child even if proved not to be the biological father, then a
DNA paternity test is probably a bad idea.
Some men rationalize that they just need to know. They say it will not affect
their relationship with the child, and they won't ever tell the mother they took
the test, no matter how the test comes out. Most often this is simply
unrealistic.
If the DNA paternity test indicates that the man is not the child's biological father, then it
may subconsciously and unintentionally change his attitude and behavior toward
the child. The DNA paternity test results sometimes also slip out unintentionally in a heated
argument with the mother, or the mother may find the laboratory report, or may
hear about it from someone the man has told. This may even cause the mother to
prevent a continuing relationship between the man and the child.
It is also possible that the child may somehow find out about the test. Learning
that the man is not the child's biological father may have a serious impact on
the child's self-image, and the child's assumptions about how the man feels
toward the child. This can occur even if the man assures the child that his
feelings toward the child are unchanged. There are many other possible adverse
consequences of the paternity test in this situation. They depend, in part, on
the individual facts of each case.
Please carefully consider all of the possible consequences before deciding to
take a DNA paternity test. There are many possible reasons to take a DNA paternity test.
But if you are a man who has assumed that you are the child's father, and you
and the child have a good loving relationship that you want to continue, and if
the only reason to take the paternity test is "because you have to know," then please
carefully weigh the possible consequences before setting up a DNA paternity test.
Please think of the child's needs, and make the choice that best protects and
promotes the incredibly important relationship you have with your child.
