Sample Reports
When
does the testing procedure begin?
 |
The laboratory begins each test once all samples
for a case have been received. The samples may reach the
lab by one of the options below depending on the location of
the tested parties.
-
If you do not require the split kit option
(the kit is shipped to more than one location) all samples must be returned to
the laboratory in the same shipping mailer.
-
If you order multiple location
shipping, each party may return his or her samples to the
laboratory separately using the provided return mailers. The laboratory
is notified of the number of incoming
samples from different locations and will begin testing
once all samples are
received. Please return the samples within three
weeks of collection.
|
How
soon can I expect the results?
|
We offer the fastest DNA paternity
testing anywhere. We
offer STAT testing options that guarantee results on either the
following business day (from the day the lab receives the
samples) or within three business days.
Our
routine turn-around times are as low as 5 days and as long as
2 weeks depending upon the kit purchased. The chart on this order
page lists the normal response time from the lab.
These
turn-around times are based on testing with cheek swab samples
only. With any
biological testing, however, exceptions can occur. There are a few reasons why your test might not be completed
in the typical time.
-
Sample Failure –
There is always a risk, although slight, of a sample not
containing enough DNA for the test.
This is due to either a collection error, or the client’s
mouth conditions (dry mouth, excessive tobacco usage,
etc.).
-
Single exclusion – We
routinely compare eleven (11) to sixteen (16) different DNA systems
between the alleged father and child.
When just one of the DNA systems we examine reveals
a mismatch between the alleged father and child,
this is called a "single exclusion".
Paternity or non-paternity cannot be concluded without further testing. Further testing will reveal either:
 |
More exclusionary DNA systems,
excluding the alleged father, or |
| More matching DNA systems,
indicating that the single exclusion is a mutational
event. A
mutational event is a naturally occurring event and
does not mean that
either the father or
child has any medical problem.
|
Double exclusion – A test
can often be classified as an exclusion if there are at
least two exclusionary DNA systems between the alleged
father and child. However,
if the two exclusionary systems reveal data that are only
one number apart, there is a remote possibility that a
double-mutational event occurred.
This is extremely rare, but since it can
occur, we must perform additional testing to provide conclusive
results.
With further testing, the same two options as for a
single exclusion (described in #2, above) are possible.
Low
Paternity Index – If all the DNA systems we
examine match between the alleged father and child,
usually the result indicates a 99.9% probability of
paternity. Sometimes,
however, the genes shared between the alleged father and
child are so common that the probability of paternity
doesn’t reach 99%.
Further testing will likely reveal additional
matches and will increase the probability to a minimum of
99%. Another
cause of low paternity index is if no race is submitted on
either the alleged father or mother, or if the race is not
of the standard race tables. The standard race
tables are Asian, Black, Caucasian, or Hispanic.
Related Alleged Fathers
– All testing assumes that the alleged fathers are
unrelated. Clients
must notify us in advance if it is possible that the fathers are
related (i.e. brothers, father and son, etc).
In such cases, additional testing will likely be
required.
|
How
do I interpret the results?
|
Once you receive your results, the following
explanation can be helpful in explaining the meaning of the
data. The paternity results are summarized in the
report's "Interpretation" section.
The results are explained in one of two ways:
-
The alleged father is excluded
as being the biological father of the child.
-
The alleged father cannot be
excluded as being the biological father of the child,
and the probability of paternity is > 99.0%
|
|
The "numbers" section of the
report reveals the DNA patterns of the individuals tested.
People have two genetic markers, or numbers, for each
DNA system analyzed. One
genetic marker was inherited from the mother, and the other
genetic marker was inherited from the father.
The order in which the genetic markers appear is
insignificant. If
the combined paternity index is a non-zero number, there is a
“match” between the alleged father and child.
If the combined paternity index is a zero, it is a
“non-match” between the alleged father and child.
A zero means that the alleged father is excluded as
being the biological father of the child.
A non-zero number means that the probability of
paternity is over 99%,

How
do I receive my result?
There are several options for receiving
your results, which are listed on the authorization form you
complete at the time of sample collection.
Results may be mailed via first class USPS mail
unless other arrangements are made at time of purchase.
The results may also be faxed or emailed allowing you to learn the
outcome immediately upon test completion.
How
do I change my notification request once the kit is sent to the
lab?
It is important to submit the correct
information at the time your samples are collected.
In order to protect your confidentiality, you may only
change your contact information (i.e. mailing address, email
address, phone or fax number, etc.) in writing and with proof of
your identity. The kit
order number and serial number are required to modify your
authorization form. Please expect a one day delay in
receiving your
results if a change is necessary.
What
if I have additional questions?
If you have any questions about your test,
please call 888-875-7574 or send an email to info@dnatestingcentre.com.
