Paternity Test
DNA paternity testing determines whether a man could be the biological father of a child. We all inherit our DNA (the genetic material) from our biological parents. A DNA paternity test compares a child’s DNA pattern with that of the alleged father to check for evidence of this inheritance—the most definitive proof of a biological relationship.
The result of a DNA paternity test is either an exclusion (the alleged father is not the biological father), or an inclusion (the alleged father is considered the biological father). For a standard paternity test, DDC guarantees at least 99.99% probability of paternity for inclusions or 100% certainty of exclusion.
Unlike in-home tests, where tested parties collect
their own samples at their convenience, DDC's paternity test uses
the Chain of Custody to ensure that you receive accurate and legally defensible results. For all of our DNA testing services, we:
- Run each test twice, following the most stringent procedures
to guarantee accurate and conclusive results.
![]() Complete testing in 3 working days (5 working days for a prenatal test). ![]() Follow a strict Chain of Custody to ensure results are legally
admissible. ![]() Maintain confidentiality of each case using strict communication
protocols.![]() Schedule convenient appointments close to your home or office
through our comprehensive network of collection sites.
Tested Parties
In a standard DNA paternity test, the tested parties include a child, the alleged father, and the mother (called a trio). The cost for this DNA test is $475. We start the testing process with only a $100 non-refundable partial payment.
The mother’s participation in the paternity
test helps to exclude half of the child’s DNA, leaving the
other half for comparison with the alleged father’s DNA. However,
we can perform a paternity test without mother’s participation
(called a motherless), which involves additional analysis, without
any additional charge. Results are equally conclusive whether or
not the mother participates. Motherless tests are guaranteed to
have at least a 99.9% probability of paternity for inclusions and
100% for exclusion.
We also can test additional children or alleged fathers
if needed; there is an additional DNA testing and analysis fee of $195 for each
additional tested party.
Sample Collection
We routinely use the painless buccal (cheek) swab to collect samples.
We have the largest network of collection sites in the U.S., allowing
our customers to choose a sample collection appointment most convenient
for them. We also have extensive affiliations with laboratories
worldwide for international sample collections.
A sample collection process fee of $70 is charged for each paternity test case (child and alleged father). The mother is collected free of charge. Sample collections for additional children or alleged fathers cost $35 each. This fee, paid directly to DDC, covers the cost of coordinating the case and includes sample collection, appointment coordination, and shipping. (Note: Due to additional procedures required by the New York State Department of Health, collection fees for appointments made in New York vary.)
Chain of Custody
Process
Samples are collected using a Chain of Custody documentation process
that ensures your results will be accepted by courts and other government
agencies.
Special DNA Paternity Testing Options
We often work with customers who would like to know the paternity
relationship even before the child is born. We’re able to
test prenatal samples in such situations. Alternatively,
we can use umbilical cord blood taken at birth—this option
is less expensive than the prenatal test, which requires special
procedures performed by an OB-GYN.
We can also test unusual samples when the father is
missing or deceased based on a viability test performed on the
samples.
For customers seeking peace of mind without intending
to use the results as legal evidence, we can recommend a company that provides the best in-home DNA paternity testing in the industry.
