What's Unique
About DNA
Specimen Type Participants Chain of Custody

Each person (except identical twins) has a unique genetic profile, irrespective of tissue origin (bone, muscle, blood, etc.). 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 tests. In the past, blood sampling used to be the common method for sample collection; 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 adhere to the swabs. Then, DNA is extracted from these cells in the lab and used to carry out the test.

Whenever a person cannot be present for direct sample collection (e.g. the person is deceased, missing or otherwise unavailable) other types of samples can be used, such as 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 (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.

Testimonials
 
"I just want to thank the continued professional and courteous service your Customer Service team provided me during the stressful waiting period for the DNA results. I contacted both your phone support and instant chat support teams at least twice and received concerned support each time. Never did I feel like they thought I might be calling too much and needed to be more patient. I truly appreciate their consideration and patience during this time."
