|Every individual has a unique
genetic profile (with the exception of identical twins) and the nuclear cells

the same DNA content. Therefore, virtually any type of biological sample/tissue can be used to generate a genetic
The most efficient way to collect a DNA sample is through buccal swabs,
they are a non-invasive,
non-traumatic, and fast
means of obtaining amounts of DNA sufficient to perform DNA tests. In the past,
blood was the common sample collected, whereas it can still be used, it does
not have the aforementioned 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; through swabbing,
epithelial cells shed from the inner cheek and adhere to the swabs. Then, DNA
is extracted from these cells in the lab and used to carry out the test.

tests, an authorized third party must perform the sample collection to establish a chain of custody, as required by
the court. If a legal test is needed, a sample collection appointment will be
scheduled by a case consultant, upon case setup.
When a person may not be present for direct sample collection (i.e., 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 it is not
guaranteed that data will be obtained (due to the nature, size and variability
of these type of samples), often, enough viable DNA is present to obtain a
partial or full genetic profile. Please contact us at
