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.
