Each person has a unique genetic
profile ( save identical twins) and the cells of a given person,
irrespective
of tissue origin
( they may come from bone, muscle, blood etc)
have
the same DNA content. Therefore any type of sample/tissue can be used to generate a genetic profile.
The most efficient way to collect a DNA sample is through buccal swabs,
as
it is non-invasive,
non
traumatic, fast and a friendly way
to obtain amounts of DNA sufficient to perform DNA tests. In the past blood
used to be the common method for sample collection, whereas it can still be
used, it does not have the just mentioned attributes of buccal swabs.
During sample collection, three buccal swabs (similar to Q-tips) are brushed
gently (yet firmly) against the patient's inner cheek; thru swabbing,
epithelial cells shed from the inner cheek, adhere to the swabs. Then, DNA is
extracted from these cells in the lab and used to carry out the test.
In the case of our
Private
Paternity Tests, buccal swabs can be collected in the privacy of one's own home by using our FREE
DNASwabTM DNA Collection Kit.
For
Legal Paternity
Test, an authorized third party must perform the sample collection to establish chain of custody as require by the
court. If a legal test is needed, a sample collection appointment will be
scheduled by our case consultant upon case setup.
Whenever a person can not be present for direct sample collection (ie: the
person is deceased, missing or unwilling) other types of samples can be used,
such us semen, hairs with roots, nails, blood stains, cigarette butts,
toothbrushes etc. These samples are considered to be forensic samples, and
while is not guaranteed (due to the nature, size and variability of these type
of samples), they often contain enough DNA to obtain a partial or full genetic
profile. Please contact us at
800-DNA-EXAM (800-362-3926) or click here to contact us before submitting a sample
which we do not make reference to, as some samples may be unacceptable.
